ANONACE^. 261 



nearly allied to AnonacecB is, in our opinion, Monimiacem, including 

 therein the Cah/canfhe(S. Eifjjoiuatla is a type wliicli very closely links 

 together the alternate-leaved Monimiacece, and the Anonacccs with 

 a more or less concave floral receptacle.' Of MonopetaltB, Ebenacece 

 have been always noted as presenting- close analogies with AnonacecB f 

 but this conjunction seems to us hardly warranted by an exact 

 analysis of their structure ; it is based on superficial characters only. 



The Anonacea are almost exclusively inhabitants of hot climates. 

 They extend over the whole world for about 40° on eacli side of the 

 equator; but in Africa they hardly pass 20° X. Europe is the only 

 quarter of the world in which none are indigenous ; the few species 

 cultivated in the open air being those from North America. The 

 sections Forcelia and Asimina of Uvaria belong to the United States, 

 Mexico, and the western regions of South America as far as Peru. 

 The south-east of this American zone, as far as the south of Brazil, 

 is the country of Aberemoa, RoUinia, Cpubopetali/m, Oxandra, and 

 most species of Anona ; indeed it is not long since only one 

 A?iona was known to be truly indigenous in the Old World.-' Now, 

 it is true, we know of several;^ but their number is, on the whole, 

 very limited, compared to that of the species from tropical America. 



De Martius has written some remarkable pages^ on the history of 

 the Anonas cultivated in South America. He asserts that Anona Clieri- 

 molia, muricata, obtiisijlora^ reticulata,d^\i(\. sq/iamo-sa have been imported 

 into Brazil, first cultivated near dwellings, and so gradually modi- 

 fied. Moreover, this author proves by historical and philological 

 reasoning that none of these plants is native in the East Indies, but 

 that all have equally been introduced into the Old World after the 

 discovery of America, and that the Antilles are their true cradle. 

 Thus A. DE Sain T-HiL AIRE is mistaken in saying that the Anonas with 

 edible fruits,^ especially A. squamosa, come from the East Indies, and
