The works of the Greeks, Romans, and Arabs make no allusion to this species, which was evidently introduced into the old world after the discovery of America. Rheede[1553] in the seventeenth century was persuaded of this; but Rumphius[1554] disputed it later, because he said the pine-apple was cultivated in his time in every part of India, and was found wild in Celebes and elsewhere. He notices, however, the absence of an Asiatic name. That given by Rheede for Malabar is evidently taken from a comparison with the jack-fruit, and is in no sense original. It is doubtless a mistake on the part of Piddington to attribute a Sanskrit name to the pine-apple, as the name _anarush_ seems to be a corruption of _ananas_. Roxburgh knew of none, and Wilson’s dictionary does not mention the word _anarush_. Royle[1555] says that the pine-apple was introduced into Bengal in 1594. Kircher[1556] says that the Chinese cultivated it in the seventeenth century, but it was believed to have been brought to them from Peru. Clusius[1557] in 1599 had seen leaves of the pine-apple brought from the coast of Guinea. This may be explained by an introduction there subsequent to the discovery of America. Robert Brown speaks of the pine-apple among the plants cultivated in Congo; but he considers the species to be an American one. Although the cultivated pine-apple bears few seeds or none at all, it occasionally becomes naturalized in hot countries. Examples are quoted in Mauritius, the Seychelles, and Rodriguez Island,[1558] in India,[1559] in the Malay Archipelago, and in some parts of America, where it was probably not indigenous—the West Indies, for instance. It has been found wild in the warm regions of Mexico (if we may trust the phrase used by Hernandez), in the province of Veraguas[1560] near Panama, in the upper Orinoco valley,[1561] in Guiana[1562] and the province of Bahia.[1563] CHAPTER V. PLANTS CULTIVATED FOR THEIR SEEDS. _Article I._—Seeds used for Food. +Cacao+—_Theobroma Cacao_, Linnæus. The genus _Theobroma_, of the order _Byttneriaceæ_, allied to the _Malvaceæ_, consists of fifteen to eighteen species, all belonging to tropical America, principally in the hotter parts of Brazil, Guiana, and Central America.
