Liberia <*- 



Pleiocarpa spec. : a shrub with slender branches, oblong to lanceolate 

 long-acuminate leaves about 3 in. by i^ in. on short petioles, 

 and globose or globose-ellipsoid berries from the old wood, 

 the berries being shortly stalked, f — -i in. long, yellow and 

 mottled with brown and enclosing i — 4 seeds ; Batombatown, 

 U7ij'U (drawing). — This is one of the plants which according 

 to Whyte arc used in collecting rubber. 



•Polyadoa (?) simii, Sta/>f{x\ov. spec): a glabrous shrub with slender 

 branches ; leaves elliptic, shortly acuminate, sub-obtuse at the 

 base, 4 — 5 in. by 2 — 2j in., coriaceous, pale green, with 7 — 8 

 slender oblique side-nerves and faint loose veins and a petiole 

 \ in. long ; flowers in terminal and axillary subsessile small 

 dense clusters, shortly pedicelled ; sepals coriaceous with 

 membranous tips, coated with resin within, rounded, very 

 small ; corolla over J in. long, tube somewhat longer than the 

 narrow lobes ; anthers just above the middle of the tube ; 

 ovary 2-carpellary glabrous with 4 ovules in two rows in each 

 carpel ; fruit, according to a drawing by Sim, consisting of 2 

 divaricate oblong yellow follicles produced into long slender 

 beaks, 2 J by f in.; Sino District, Sim, 16! — Sim states that 

 it yields good rubber. It has quite the habitus of a Polyadoa, 

 but differs in the small number of ovules from the other species 

 of that genus. As, moreover, the fruit of Polyadoa is unknown, 

 the generic position of the plant is somewhat doubtful. No 

 species of Polyadoa and their immediate allies {^Pleiocarpa and 

 Hunteria) are known to yield rubber. 



Raawolfia cumminsii, Stapf: a glabrous shrub with slender quad-

•E. liberiensis, Stapf (Plate 254J : a glabrous shrub with terete 

 branches, membranous leaves in whorls of 4, small flowers
