8. thierryanus, K. Schum, & Gilg in Engl. Jahrb, xxxii. 158, seems to represent 
a particularly hispid state of S. hispidus. There is nothing else in the description 
to distinguish it from this species except the somewhat shorter corolla-tails, a rather 
variable character, It was collected by Thierry in the interior of Togo, where it is 
used by the Moba Tribe for preparing an arrow poison, 
9. S. bullenianus, Mast. in Gard. Chron. 1870, 1471, fig. 257, 
exel. fruit. A climbing shrub, 10-40 ft. high; branches slender, 
sparingly hispid with yellowish spreading hairs, soon glabrescent,

oblong, suddenly constricted into a narrow linear acumen 6—9 lin. long, 
rounded or (rarely) acute at the base, 4-6 in. long, 14-2 in. broad, 
membranous, very scantily hirsute or almost glabrous above, hirsute or 
hispid all over, but especially along the nerves below ; secondary nerves 
‘-11 on each side, raised and very distinct below : veins inconspicuous ; 
petiole hispid, 2—4 lin. long. Cymes terminal, peduncled, few-flowered, 
very lax, scantily hispid ; peduncle slender, 6-12 lin. long; bracts fili-

_ The fruit figured by Masters belongs to a species of Pleioceras ; the same is 
‘vidently the case with the fruits and seeds described as those of S. bullenianus by 
Christy, New Comm. Plants and Drugs, No. 9 (1886), 62.

(12919) between Mafura and Mundame, Cameroons, does not, judging from the 
(escription, differ from S. bullenianus except in the density of the indumentum.
