262 NATURAL HISTORY OF PLANTS. 



that the Portuguese introduced them from thence into their American 

 colonies ; for that species is found in Asia with all the appearance 

 rather of a naturalized plant.' Now-a-days, more than ever, does R. 

 Brown's opinion,' as to the American origin of the A/iotias cultivated 

 for their fruits, seem to prevail. 



Cananga belongs to both the east and the west of America, 

 from the south of ^lexico to the south of Brazil ; it is very abundant 

 in Guiana, the Antilles, and Peru. The sections of Uiiona, Tri(/i/ncia 

 and Unonastniniy also belong to this region. 



Besides Uvaria, Unona, and Anona, four other genera are common 

 to both hemispheres : — Xi/Iopia, Bocagea, Anaxagorea, and Phaanthus. 

 Xglopifi is distributed over the largest geographical area ; it has 

 representatives in tropical Africa, Madagascar, India and the Indian 

 Archipelago, Polynesia, the Antilles, Guiana, and as far as the south 

 of Brazil, The genus Bocagca consists of several Brazilian species 

 and all the AJphonseaa of tropical Asia ; a single species inhabits the 

 Comoro Isles. Phaanihus is disseminated over a wide area, one 

 species coming from Brazil, two from tropical Africa, and as many 

 from the Indian Archipelago. Anaxagorea is about equally divided 

 between the tropical regions of Asia and America. 



All the other A/iouaccce belong to the Old World. Ei/pomalia is 

 essentially Australian. We only find Monodora and Heralohus proper 

 in Madagascar and tropical Africa ; Enantia and Cleistorhlamgx are 

 exclusively African. The following genera have as yet only been 

 observed in tropical Asia or the neighbouring parts of Oceania : — 

 Sagcrcea, Sphcerot/ialamm, Cgalhocalg.v, Disepalum, Atrutregia, Mttre- 

 pliora, Owp/iaa ; while in both tropical Asia and tropical Africa we 

 lind Popuu-ia, M'diusa, O.rgiiiitrn, Arta/jotrgs, besides two genera that 

 are, as we have seen, represented in America, U/ioiia and Uran'a. 



Tiie two last-named genera extend over the largest area from 

 north to south, both approaching the extreme limits of the zone 

 80° broad that the Ano/iacece occupy. Both commence in the 

 North of India and fniish in Australia with the last representatives 

 of the order. The genus Uoaria goes as lar north as China and, b}- 

 Aniiiiitia, as the United States ; and as iar south as the boun- 

 dary line of tlie A/ioikiccw at the southernmost point ol' Australia.
