Strempeliopsis. 



A genus established in 1876 by Messrs. Bentham and Hooker, its characters being 

 little known : only one species is noticed, 



1. Strempeliopsis cubensis, Benth. & Hook. Gen. iL 702 : Rauwolfia strempelioides, Griseb. Cat. PI. 

 Cub. 170 : in herb. Hook, {non vidi) . 



All that is said regarding this is, that it is an erect, branching, glabrous shrub, with 

 2 minute stipules at the axUs, opposite penninerved leaves, terminal cymes with 

 niunerous small flowers; sepals 5, ovate, biauriculate at the base, eglandulous; corolla

 ovules many in each carpel, biserial ; follicles 2, erect or diverging, linear, subterete

PlTJMERIA. 



This handsome genus requires Httle notice, as its species have beeniully described, and 

 many of -them well illustrated. They are all of Peruvian, Mexican, or Brazilian origin, 30 of 

 them being enumerated by DeCandoUe, and 15 others by Miiller. They are mostly lofty 

 trees or tall erect shrubs, much branched, the trunks affording a solid wood, the branch-
