B. Staiidtii, Pax in Engl. Jalnb. xxiii. 532, and in Engl. Ptianzenr. Euphorb.- 

 Cluytiea', 49, has hermaphrodite flowers, and is therefore not Euphorbiaceous. It 

 seems to belong to Anacardiacece, of which order it mny represent a new genus.

on botli surfaces when mature; stamens 15-16 . . 2. R. Rautanenii.
