 patent ; leaves dryly coriaceous, hard, glossy above ; drupe green, 

 crowned with the bifid style or its remains ; the style-branches 

 bipartite, stigmatose on the inner side ; cotyledons large, incumbent.

Island of St. Thomas. — A handsome tree, with strict trunk and 

 white wood. In mountain forests between the town and Monte Caffe, 

 at an elevation from 1800 to 2000 ft. ; fr. Dec. 1860. Negro name 

 " Coaco branco."' No. 6304. 



This is apparently the same species as a plant collected by G. Don 

 in St. Thomas's Island, and mentioned by Planchon and Henriques, 

 U.cc. ; the leaves in Welwitsch's specimen are, however, rather smaller, 

 about 3 in. long by an inch broad ; the fruit is about ^ in. broad, 1^ in. 

 long, J in. thick. Don's plant has been considered by Henriques, I.e., 

 as the same species as Wight's Indian plant, and therefore Welwitsch's 

 specimen should probably be referred to the same, as given above. 

 Hook. f. in Fl. Brit. Ind. v. p. 483 (Dec. 1888) suspected that 

 C. philippensis is not distinct from C. Wightii.
