In spite of the entirely wild appearance of the hop in Europe in districts far from cultivation, it has been sometimes asked if it is not of Asiatic origin.784 I do not think this can be proved, nor even that it is likely. The fact that the Greeks and Latins have not spoken of the use of the hop in making beer is easily explained, as they were almost entirely unacquainted with this drink. If the Greeks have not mentioned the plant, it is simply perhaps because it is rare in their country. From the Italian name lupulo it seems likely that Pliny speaks of it with other vegetables under the name lupus salictarius.785 That the custom of brewing with hops only became general in the Middle Ages proves nothing, except that other plants were formerly employed, as is still the case in some districts. The Kelts, the Germans, other peoples of the north and even of the south who had the vine, made beer786 either of barley or of other fermented grain, adding in certain cases different vegetable substances – the bark of the oak or of the tamarisk, for instance, or the fruits of Myrica gale.787 It is very possible that they did not soon discover the advantages of the hop, and that even after these were recognized, they employed wild hops before beginning to cultivate them. The first mention of hop-gardens occurs in an act of donation made by Pepin, father of Charlemagne, in 768.788 In the fourteenth century it was an important object of culture in Germany, but it began in England only under Henry VIII.789
The common names of the hop only furnish negative indications as to its origin. There is no Sanskrit name,790 and this agrees with the absence of the species in the region of the Himalayas, and shows that the early Aryan peoples had not noticed and employed it. I have quoted before791 some of the European names, showing their diversity, although some few of them may be derived from a common stock. Hehn, the philologist, has treated of their etymology, and shown how obscure it is, but he has not mentioned the names totally distinct from humle, hopf or hop, and chmeli of the Scandinavian, Gothic, and Slav races; for example, Apini in Lette, Apwynis in Lithuanian, tap in Esthonian, blust in Illyrian,792 which have evidently other roots. This variety tends to confirm the theory that the species existed in Europe before the arrival of the Aryan nations. Several different peoples must have distinguished, known, and used this plant successively, which confirms its extension in Europe and in Asia before it was used in brewing.
Carthamine—Carthamus tinctorius, Linnæus.
The composite annual which produces the dye called carthamine is one of the most ancient cultivated species. Its flowers are used for dyeing in red or yellow, and the seeds yield oil.
The grave-cloths which wrap the ancient Egyptian mummies are dyed with carthamine,793 and quite recently fragments of the plant have been found in the tombs discovered at Deir el Bahari.794 Its cultivation must also be ancient in India, since there are two Sanskrit names for it, cusumbha and kamalottara, of which the first has several derivatives in the modern languages of the peninsula.795 The Chinese only received carthamine in the second century B.C., when Chang-kien brought it back from Bactriana.796 The Greeks and Latins were probably not acquainted with it, for it is very doubtful whether this is the plant which they knew as cnikos or cnicus.797 At a later period the Arabs contributed largely to diffuse the cultivation of carthamine, which they named qorton, kurtum, whence carthamine, or usfur, or ihridh, or morabu,798 a diversity indicating an ancient existence in several countries of Western Asia or of Africa. The progress of chemistry threatens to do away with the cultivation of this plant as of many others, but it still subsists in the south of Europe, in the East, and throughout the valley of the Nile.799
No botanist has found the carthamine in a really wild state. Authors doubtfully assign to it an origin in India or Africa, in Abyssinia in particular, but they have never seen it except in a cultivated state, or with every appearance of having escaped from cultivation.800
Mr. Clarke,801 formerly director of the Botanical Gardens in Calcutta, who has lately studied the Compositæ of India, includes the species only as a cultivated one. The summary of our modern knowledge of the plants of the Nile region, including Abyssinia, by Schweinfurth and Ascherson,802 only indicates it as a cultivated species, nor does the list of the plants observed by Rohlfs on his recent journey mention a wild carthamine.803
As the species has not been found wild either in India or in Africa, and as it has been cultivated for thousands of years in both countries, the idea occurred to me of seeking its origin in the intermediate region; a method which had been successful in other cases.
Unfortunately, the interior of Arabia is almost unknown. Forskal, who has visited the coasts of Yemen has learnt nothing about the carthamine; nor is it mentioned among the plants of Botta and of Bové. But an Arab, Abu Anifa, quoted by Ebn Baithar, a thirteenth-century writer, expressed himself as follows:804– “Usfur, this plant furnishes a substance used as a dye; there are two kinds, one cultivated and one wild, which both grow in Arabia, of which the seeds are called elkurthum.” Abu Anifa was very likely right.
Saffron—Crocus sativus, Linnæus.
The saffron was cultivated in very early times in the west of Asia. The Romans praised the saffron of Cilicia, which they preferred to that grown in Italy.805 Asia Minor, Persia, and Kashmir have been for a long time the countries which export the most. India gets it from Kashmir806 at the present day. Roxburgh and Wallich do not mention it in their works. The two Sanskrit names mentioned by Piddington807 probably applied to the substance saffron brought from the West, for the name kasmirajamma appears to indicate its origin in Kashmir. The other name is kunkuma. The Hebrew word karkom is commonly translated saffron, but it more probably applies to carthamine, to judge from the name of the latter in Arabic.808 Besides, the saffron is not cultivated in Egypt or in Arabia. The Greek name is krokos.809 Saffron, which recurs in all modern European languages, comes from the Arabic sahafaran,810 zafran.811 The Spaniards, nearer to the Arabs, call it azafran. The Arabic name itself comes from assfar, yellow.
Trustworthy authors say that C. sativus is wild in Greece812 and in the Abruzzi mountains in Italy.813 Maw, who is preparing a monograph of the genus Crocus, based on a long series of observations in gardens and in herbaria, connects with C. sativus six forms which are found wild in mountainous districts from Italy to Kurdistan. None of these, he says,814 are identical with the cultivated variety; but certain forms described under other names (C. Orisnii, C. Cartwrightianus, C. Thomasii), hardly differ from it. These are from Italy and Greece.
The cultivation of saffron, of which the conditions are given in the Cours d’Agriculture by Gasparin, and in the Bulletin de la Société d’Acclimatation for 1870, is becoming more and more rare in Europe and Asia.815 It has sometimes had the effect of naturalizing the species for a few years at least in localities where it appears to be wild.
CHAPTER IV.
PLANTS CULTIVATED FOR THEIR FRUITS.816
Sweet Sop, Sugar Apple 817—Anona squamosa, Linnæus. (In British India, Custard Apple; but this is the name of Anona muricata in America.)
The original home of this and other cultivated Anonaceæ has been the subject of doubts, which make it an interesting problem. I attempted to resolve them in 1855. The opinion at which I then arrived has been confirmed by the subsequent observations of travellers, and as it is useful to show how far probabilities based upon sound methods lead to true assertions, I will transcribe what I then said,818 mentioning afterwards the more recent discoveries.
“Robert Brown proved in 1818 that all the species of the genus Anona, excepting Anona senegalensis, belong to America, and none to Asia. Aug. de Saint-Hilaire says that, according to Vellozo, A. squamosa was introduced into Brazil, that it is known there under the name of pinha, from its resemblance to a fir-cone, and of ata, evidently borrowed from the names attoa and atis, which are those of the same plant in Asia, and which belong to Eastern languages. Therefore, adds de Saint-Hilaire,819 the Portuguese transported A. squamosa from their Indian to their American possessions, etc.”
Having made in 1832 a review of the family of the Anonaceæ,820 I noticed how Mr. Brown’s botanical argument was ever growing stronger; for in spite of the considerable increase in the number of described Anonaceæ, no Anona, nor even any species of Anonaceæ with united ovaries, had been found to be a native of Asia. I admitted821 the probability that the species came from the West Indies or from the neighbouring part of the American continent; but I inadvertently attributed this opinion to Mr. Brown, who had merely indicated an American origin in general.822
Facts of different kinds have since confirmed this view.
“Anona squamosa has been found wild in Asia, apparently as a naturalized plant; in Africa, and especially in America, with all the conditions of an indigenous plant. In fact, according to Dr. Royle,823 the species has been naturalized in several parts of India; but he only saw it apparently growing wild on the side of the mountain near the fort of Adjeegurh in Bundlecund, among teak trees. When so remarkable a tree, in a country so thoroughly explored by botanists, has only been discovered in a single locality beyond the limits of cultivation, it is most probable that it is not indigenous in the country. Sir Joseph Hooker found it in the isle of St. Iago, of the Cape Verde group, forming woods on the hills which overlook the valley of St. Domingo.824 Since A. squamosa is only known as a cultivated plant on the neighbouring continent;825 as it is not even indicated in Guinea by Thonning,826 nor in Congo,827 nor in Senegambia,828 nor in Abyssinia and Egypt, which proves a recent introduction into Africa; lastly, as the Cape Verde Isles have lost a great part of their primitive forests, I believe that this is a case of naturalization from seed escaped from gardens. Authors are agreed in considering the species wild in Jamaica. Formerly the assertions of Sloane829 and Brown830 might have been disregarded, but they are confirmed by Macfadyen.831 Martius found the species wild in the virgin forests of Para.832 He even says, ‘Sylvescentem in nemoribus paraensibus inveni,’ whence it may be inferred that these trees alone formed a forest. Splitgerber833 found it in the forests of Surinam, but he says, ‘An spontanea?’ The number of localities in this part of America is significant. I need not remind my readers that no tree growing elsewhere than on the coast has been found truly indigenous at once in tropical Asia, Africa, and America.834 The result of my researches renders such a fact almost impossible, and if a tree were robust enough to extend over such an area, it would be extremely common in all tropical countries.
“Moreover, historical and philological facts tend also to confirm the theory of an American origin. The details given by Rumphius835 show that Anona squamosa was a plant newly cultivated in most of the islands of the Malay Archipelago. Forster does not mention the cultivation of any Anonacea in the small islands of the Pacific.836 Rheede837 says that A. squamosa is an exotic in Malabar, but was brought to India, first by the Chinese and the Arabs, afterwards by the Portuguese. It is certainly cultivated in China and in Cochin-China,838 and in the Philippine Isles,839 but we do not know from what epoch. It is doubtful whether the Arabs cultivate it.840 It was cultivated in India in Roxburgh’s day;841 he had not seen the wild plant, and only mentions one common name in a modern language, the Bengali ata, which is already in Rheede. Later the name gunda-gatra842 was believed to be Sanskrit, but Dr. Royle843 having consulted Wilson, the famous author of the Sanskrit dictionary, touching the antiquity of this name, he replied that it was taken from the Sabda Chanrika, a comparatively modern compilation. The names of ata, ati, are found in Rheede and Rumphius.844 This is doubtless the foundation of Saint-Hilaire’s argument; but a nearly similar name is given to Anona squamosa in Mexico. This name is ate, ahate di Panucho, found in Hernandez845 with two similar and rather poor figures which may be attributed either to A. squamosa, as Dunal846 thinks, or to A. cherimolia, according to Martius.847 Oviedo uses the name anon.848 It is very possible that the name ata was introduced into Brazil from Mexico and the neighbouring countries. It may also, I confess, have come from the Portuguese colonies in the East Indies. Martius says, however, that the species was imported from the West India Islands.849 I do not know whether he had any proof of this, or whether he speaks on the authority of Oviedo’s work, which he quotes and which I cannot consult. Oviedo’s article, translated by Marcgraf,850 describes A. squamosa without speaking of its origin.
“The sum total of the facts is altogether in favour of an American origin. The locality where the species usually appears wild is in the forests of Para. Its cultivation is ancient in America, since Oviedo is one of the first authors (1535) who has written about this country. No doubt its cultivation is of ancient date in Asia likewise, and this renders the problem curious. It is not proved, however, that it was anterior to the discovery of America, and it seems to me that a tree of which the fruit is so agreeable would have been more widely diffused in the old world if it had always existed there. Moreover, it would be difficult to explain its cultivation in America in the beginning of the sixteenth century, on the hypothesis of an origin in the old world.”
Since I wrote the above, I find the following facts published by different authors: —
1. The argument drawn from the fact that there is no Asiatic species of the genus Anona is stronger than ever. A. Asiatica, Linnæus, was based upon errors (see my note in the Géogr. Bot., p. 862). A. obtusifolia (Tussac, Fl. des Antilles, i. p. 191, pl. 28), cultivated formerly in St. Domingo as of Asiatic origin, is also perhaps founded upon a mistake. I suspect that the drawing represents the flower of one species (A. muricata) and the fruit of another (A. squamosa). No Anona has been discovered in Asia, but four or five are now known in Africa instead of only one or two,851 and a larger number than formerly in America.
2. The authors of recent Asiatic floras do not hesitate to consider the Anonæ, particularly A. squamosa, which is here and there found apparently wild, as naturalized in the neighbourhood of cultivated ground and of European settlements.852
3. In the new African floras already quoted, A. squamosa and the others of which I shall speak presently are always mentioned as cultivated species.
4. McNab, the horticulturist, found A. squamosa in the dry plains of Jamaica,853 which confirms the assertions of previous authors. Eggers says854 that the species is common in the thickets of Santa Cruz and Virgin Islands. I do not find that it has been discovered wild in Cuba.
5. On the American continent it is given as cultivated.855 However, M. André sent me a specimen from a stony district in the Magdalena valley, which appears to belong to this species and to be wild. The fruit is wanting, which renders the matter doubtful. From the note on the ticket, it is a delicious fruit like that of A. squamosa. Warming856 mentions the species as cultivated at Lagoa Santa in Brazil. It appears, therefore, to be cultivated or naturalized from cultivation in Para, Guiana, and New Granada.
In fine, it can hardly be doubted, in my opinion, that its original country is America, and in especial the West India Islands.
Sour Sop—Anona muricata, Linnæus.
This fruit-tree,857 introduced into all the colonies in tropical countries is wild in the West Indies; at least, its existence has been proved in the islands of Cuba, St. Domingo, Jamaica, and several of the smaller islands.858 It is sometimes naturalized on the continent of South America near dwellings.859 André brought specimens from the district of Cauca in New Granada, but he does not say they were wild, and I see that Triana (Prodr. Fl. Granat.) only mentions it as cultivated.
Custard Apple in the West Indies, Bullock’s Heart in the East Indies —Anona reticulata, Linnæus.
This Anona, figured in Descourtilz, Flore Médicale des Antilles, ii. pl. 82, and in the Botanical Magazine, pl. 2912, is wild in Cuba, Jamaica, St. Vincent, Guadeloupe, Santa Cruz, and Barbados,860 and also in the island of Tobago in the Bay of Panama,861 and in the province of Antioquia in New Granada.862 If it is wild in the last-named localities as well as in the West Indies, its area probably extends into several states of Central America and of New Granada.
Although the bullock’s heart is not much esteemed as a fruit, the species has been introduced into most tropical colonies. Rheede and Rumphius found it in plantations in Southern Asia. According to Welwitsch, it has naturalized itself from cultivation in Angola, in Western Africa,863 and this has also taken place in British India.864
Chirimoya—Anona Cherimolia, Lamarck.
The chirimoya is not so generally cultivated in the colonies as the preceding species, although the fruit is excellent. This is probably the reason that there is no illustration of the fruit better than that of Feuillée (Obs., iii. pl. 17), while the flower is well represented in pl. 2011 of the Botanical Magazine, under the name of A. tripetala.
In 1855, I wrote as follows, touching the origin of the species:865 “The chirimoya is mentioned by Lamarck and Dunal as growing in Peru; but Feuillée, who was the first to speak of it,866 says that it is cultivated. Macfadyen867 says it abounds in the Port Royal Mountains, Jamaica; but he adds that it came originally from Peru, and must have been introduced long ago, whence it appears that the species is cultivated in the higher plantations, rather than wild. Sloane does not mention it. Humboldt and Bonpland saw it cultivated in Venezuela and New Granada; Martius in Brazil,868 where the seeds had been introduced from Peru. The species is cultivated in the Cape Verde Islands, and on the coast of Guinea,869 but it does not appear to have been introduced into Asia. Its American origin is evident. I might even go further, and assert that it is a native of Peru, rather than of New Granada or Mexico. It will probably be found wild in one of these countries. Meyen has not brought it from Peru.”870
My doubts are now lessened, thanks to a kind communication from M. Ed. André. I may mention first, that I have seen specimens from Mexico gathered by Botteri and Bourgeau, and that authors often speak of finding the species in this region, in the West Indies, in Central America, and New Granada. It is true, they do not say that it is wild. On the contrary, they remark that it is cultivated, or that it has escaped from gardens and become naturalized.871 Grisebach asserts that it is wild from Peru to Mexico, but he gives no proof. André gathered, in a valley in the south-west of Ecuador, specimens which certainly belong to the species as far as it can be asserted without seeing the fruit. He says nothing as to its wild nature, but the care with which he points out in other cases plants cultivated or perhaps escaped from cultivation, leads me to think that he regards these specimens as wild. Claude Gay says that the species has been cultivated in Chili from time immemorial.872 However, Molina, who mentions several fruit trees in the ancient plantations of the country, does not speak of it.873
In conclusion, I consider it most probable that the species is indigenous in Ecuador, and perhaps in the neighbouring part of Peru.
Oranges and Lemons—Citrus, Linnæus.
The different varieties of citrons, lemons, oranges, shaddocks, etc., cultivated in gardens have been the subject of remarkable works by several horticulturists, among which Gallesio and Risso874 hold the first rank. The difficulty of observing and classifying so many varieties was very great. Fair results have been obtained, but it must be owned that the method was wrong from the beginning, since the plants from which the observations were taken were all cultivated, that is to say, more or less artificial, and perhaps in some cases hybrids. Botanists are now more fortunate. Thanks to the discoveries of travellers in British India, they are able to distinguish the wild and therefore the true and natural species. According to Sir Joseph Hooker,875 who was himself a collector in India, the work of Brandis876 is the best on the Citrus of this region, and he follows it in his flora. I shall do likewise in default of a monograph of the genus, remarking also that the multitude of garden varieties which have been described and figured for centuries, ought to be identified as far as possible with the wild species.877
The same species, and perhaps others also, probably grow wild in Cochin-China and in China; but this has not been proved in the country itself, nor by means of specimens examined by botanists. Perhaps the important works of Pierre, now in course of publication, will give information on this head for Cochin-China. With regard to China, I will quote the following passage from Dr. Bretschneider,878 which is interesting from the special knowledge of the writer: – “Oranges, of which there are a great variety in China, are counted by the Chinese among their wild fruits. It cannot be doubted that most of them are indigenous, and have been cultivated from very early times. The proof of this is that each species or variety bears a distinct name, besides being in most cases represented by a particular character, and is mentioned in the Shu-king, Rh-ya, and other ancient works.”
Men and birds disperse the seeds of Aurantiaceæ, whence results the extension of its area, and its naturalization in all the warm regions of the two worlds. It was observed879 in America from the first century after the conquest, and now groves of orange trees have sprung up even in the south of the United States.
Shaddock—Citrus decumana, Willdenow.
I take this species first, because its botanical character is more marked than that of the others. It is a larger tree, and this species alone has down on the young shoots and the under sides of the leaves. The fruit is spherical, or nearly spherical, larger than an orange, sometimes even as large as a man’s head. The juice is slightly acid, the rind remarkably thick. Good illustrations of the fruit may be seen in Duhamel, Traité des Arbres, edit. 2, vii. pl. 42, and in Tussac, Flore des Antilles, iii. pls. 17, 18. The number of varieties in the Malay Archipelago indicates an ancient cultivation. Its original country is not yet accurately known, because the trees which appear indigenous may be the result of naturalization, following frequent cultivation. Roxburgh says that the species was brought to Calcutta from Java,880 and Rumphius881 believed it to be a native of Southern China. Neither he nor modern botanists saw it wild in the Malay Archipelago.882 In China the species has a simple name, yu; but its written character883 appears too complicated for a truly indigenous plant. According to Loureiro, the tree is common in China and Cochin-China, but this does not imply that it is wild.884 It is in the islands to the east of the Malay Archipelago that the clearest indications of a wild existence are found. Forster885 formerly said of this species, “very common in the Friendly Isles.” Seemann886 is yet more positive about the Fiji Isles. “Extremely common,” he says, “and covering the banks of the rivers.”
