. EUPHORBIACE^. m 



Adenophwdru^ from tropical America, are species of Bernardia with 

 from 3-6 stamens inserted upon a non -glandular receptacle, and hav- 

 ing anthers surmounted with a large gland. Acidoton^ a shi-ub from 

 Jamaica, has almost the same characters as Bernardia ; but the in- 

 sertion of the style is central, and the conical receptacle of the male 

 iiowers thickens into a glandular tissue between and outside the 

 stamens. Cleidion, belonging to the warm regions of the Old 

 World, except two American species, has also valvate sepals in the 

 male flowers, the female ones being imbricated. The stamens are 

 very exactly grouped in vertical series which are alternate and 

 strictly imbricated ; the style has two or three large bifiu'cate 

 branches. Endospermum^ formed of trees from China, Malaysia, and 

 Borneo, has a gamosepalous dentate calyx, imbricated when uji- 

 right, and a variable number of stamens (from 6-10) disposed in 

 two verticils, with peltate anthers 3-4-valved. The bilocular ovary 

 is succeeded by an indehiscent monospermous fruit. ErismantJius^ 

 a shrub from Pcuang, has apetalous fl[owers, an imbricated calyx, 

 oblique in the male flowers, from eight to fifteen stamens, introrse 

 anthers, and a three-celled ovary. In Dilfa myrkoidea^ from Cuba, 

 imperfectly known and doubtfully placed beside the preceding genus, 

 the calyx of the female flowers disappears and the subtb-upaceous 

 fruit is borne upon a pedicel, with some entire or palmipartite bracts. 



Adrhina cannot be separated from the preceding types. It is 

 Australian and consists of frutescent plants with opposite or alter- 

 nate leaves, a valvate calyx in the male flowers, an imbricated one 

 in the female without corolla and without disk, central stamens inde- 

 finite in number, and a three-shelled capsular frviit. Ncohoutonia 

 qfricana, placed beside it, has the same floral organization, with a 

 disk well developed in both sexes. In Treivia, consisting of Asiatic 

 trees with opposite leaves, the 3-4-merous apetalous flowers without 

 disk arc also very similar. The suberous indehiscent fruit has three 

 or four cells, each containing an exarillate seed. Lasiocroton niacro- 

 phijllm^ a Jamaican genus, imperfectly known, is reported to have 

 nciarly the same flowers as the preceding, with an hypogynous disk 

 in the female flower only, and a capsular fruit. Pijcnocoma^ formed 

 of trees and shrubs from tropical, continental, and insular Africa, 

 are nearly related to Trcwia, EeJiinm^ 'M\i\. Adriana. They have large 

 alternate elongated leaves, flowers in long racemes of one or two
