This is undoubtedly a species of Pleiocarpa, evidently very close to P. bicar- 
pellata.

A curious state of this species was collected by Whyte in Liberia, within 20 
miles of Karka Town. It has an appearance rather different from that of the other 
specimens of R, Cumminsii, owing to the more. abundant development of inflores- 
cences and the reduction of the foliage. The fruits are mostly solitary mericarps 
and convex on both sides, although much more so on one side tian on the other. 
The young flowers of the specimen agree, as far as they go, exactly with those of 
R. Cumminsii. 
13a. Rauwolfia liberiensis, Siap/. <A perfectly glabrous shrub ; 
young branches terete or the youngest slightly angular. Leaves in 
whorls of usually 4, lanceolate or oblanceolate, acutely acuminate, long 
attenuate at the base, 3-6 in. long, {-14 in. broad, thinly membranous ; 
secondary nerves 9-12 on each side, much spreading, curved ; veins 
quite obscure; petioles 3-6 lin. long. Flowers pedicelled in 5-7- 
flowered umbellitorm cymes; cymes gathered in a 5-rayed umbel ; 
peduncle slender, up to 1} in. long; rays 5-10 lin. long, more or less 
unequal ; pedicels very slender, up to 2 lin. long. Calyx } lin. long; 
segments ovate, acute. Corolla-tube 2~24 lin. long, villous near the 
mouth, pubescent below the stamens within ; lobes su brotundate, obtuse, 
scarcely 4 lin. long. Carpels free surrounded by a truncate disc to the 
middle. Style glabrous, Fruit unknown. 
Upper Guinea. Liberia; Sinou Basin, Whyte! 
Very similar to 2. mombasiana, but less robust, with shorter petiole:, fewer 
secondary nerves, less compound inflorescences and slightly smaller flowers.
