AND TROPICAL AFRICA. 169 



The genus Pentaspadon falls naturally into a group of Anacardiece, characterized by a 

 1-cellecl, 1-ovuled ovary, and laterally or basally attached ovule, and mil rank in it with 

 Rhus, Pistacia, and Sorindeia. It differs from Ifcmgifera, Anacardiuni, and Glutei in 

 the compound leaves and laterally attached ovule. The small calyx, comparatively large 

 imbricating petals, short stamens with alternate spathulate or capitate staminodia, the 

 staminodia, and depressed ovary with short, very broad, recurved stigma, well characterize 

 the genus.

This remarkable plant belongs to the tribe Anacardiece of Terebinthacese, and to the 

 section with a unilocular ovary and the ovule solitary and suspended. Its immediate allies 

 I consider to be, Odina, which has eight stamens and a very different fruit ; Tapiria, which 

 has ten stamens and a 4-lobed disk ; 'Solenocariyus, which has valvate petals and ten 

 stamens ; Smodimgium, in which the stamens are five and the drupe winged ; and Schiniis, 

 which has also ten stamens : aU these, however, I beheve, form one group with Hcema- 

 tostapliis, differing from the other unilocular monospermou.s Anacardiece with ovules 

 suspended from near the apex of the cell, in tlieu' compound leaves, and calyx not accres- 

 cent or adnate after flowering. It differs from all in the trimerous irregular flowers and 

 in habit. 



Mr. Barter describes this plant as a small tree, with deciduous tortuous branches, and 

 deep- crimson fruit like bunches of grapes (whence the generic name). The drupes are 

 eatable, acid but not unpleasant.
