PLANTS CULTIVATED FOR THEIR FRUITS. 169 



Saint-Hilaire,^ the Portuguese transported A, squamosa 

 from their Indian to their American possessions, etc." 



Having made in 1832 a review of the family of the 

 Anonacese,^ I noticed how Mr. Brown's botanical argument 

 was ever growing stronger; for in spite of the considerable 

 increase in the number of described Anonacese, no Anona, 

 nor even any species of Anonacese with united ovaries, 

 had been found to be a native of Asia. I admitted^ 

 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.^ 



Facts of different kinds have since confirmed this 

 view. 



" Avona squamosa has been found wild in Asia, 

 apparently as a naturalized plant ; in Africa, and espe- 

 cially in America, with all the conditions of an indigenous 

 plant. In fact, according to Dr. Boyle,^ the species has 

 been naturalized in several parts of India ; but he only 

 saw it apparently growing wild on the side of the moun- 

 tain 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. lago, of the 

 Cape Verde group, forming woods on the hills which over- 

 look the valley of St. Domingo.^ Since A. sqiiaraosa 

 is only known as a cultivated plant on the neighbouring 

 continent ; "^ as it is not even indicated in Guinea by 

 Thonning,^ nor in Congo,^ nor in Senegambia,^^ nor in
