146 LXXXIV. APOCYNACEE (STAPF). [ Conopharyngia. 
white, fragrant; tube very fleshy, wide, oblong-ellipsoid, constricted 
below the mouth, 1 in. long or slightly longer, 4—5 lin. wide, densely 
tomentose within except along the middle lines of the filamental ridges 
and short lines between the bases of the stamens; lobes oblong, 8-18 
lin. long, margins wavy. Stamens inserted at the middle of the corolla- 
tube; anthers 6 lin. long, almost reaching the mouth. Style 5 lin. 
long.—Tabernemontana pachysiphon, Stapf in Kew Bulletin, 1894, 22.

Leaves sent by Miss Gurney from “West Africa” under the name Kpokpoka 
belong very probably to this species. They were referred by Morris (in Journ. Soc. 
Arts, xlvi. 778), to C. crassa, which is stated there to yield part of the rubber of 
Sierra Leone and the Gold Coast. Neither C. crassa nor C. pachysiphon have been, 
so far, observed in these colonies, and experiments made in Ceylon to obtain rubber 
from a cultivated specimen of “ Tabernemontana crassa” have been unsuccessful 
(see Vilbouchevitch in Warb. Plant. 4 Caoutch, 208, in note). 
I referred (in De Wild. & Durand, Contrib. Fl. Congo in Ann. Mus. Congo, Bot. 
sér. 1, i. fase. i. 40) a plant collected by Dewévre on the Upper Congo near Kasongo 
to this species. Having revised this group since, I have no doubt now that 
Dewévre’s plant does not belong here, but am unable to assign it to its proper place 
in the absence of the specimen.
