resemblance to that plant. The figure in \question is a fairly good one for that 
period and is undoubtedly a representation of Leptadenia heterophylla, Decne. 
The plant described by Schultes as Secamone Alpini is characterisecl in such an un- 
mistakable manner that is is quite evident the description was mawe entirely from 
the Seuth African, without reference to the Egyptian plant of Alpin o, 
5. S. platystigma, K. Schum. in Engl. Jahrb. xvii. 148. A 
glabrous climber. Leaves 14—24in. long, 1-114 in. broad, shortly petio- 
late, varying from lanceolate to elliptic-oblong, acuminate, rounded or 
broadly cuneate at the base. Cymes usually numerous, «axillary and 
terminal on lateral shoots, many-flowered, 3-1} in. in diam., more or 
less clothed with minute incurved rust-coloured hairs ; brancnes widely 
spreading ; peduncles 3-1} in. long ; bracts % lin. long, ovate, obtuse, 
minutely ciliate; pedicels 1-1} lin. long, glabrous. Sepals 3-1 lin. 
long, broadly ovate, obtuse, minutely ciliate. Corolla rotate-cam panu- 
late ; lobes 14 lin. long, twice as long as the tube, oblong, obtuse, 
glabrous or with a somewhat velvety surface within, but not pubescent. 
Coronal-lobes reaching nearly to the tips of the anthers, falcate, in- 
curved. Anthers more or less bearded or laciniate at the apex. Style 
protruded much beyond the anthers; apical part stout, ovoid-clavate, 
two-lobed or rarely entire-——K. Schum. in Engl. & Prantl, Pflanzenfam.

The plate of Torocarpus africanus, Oliv., is inaccurate as to the open flowers on 
the plant, and also as to the analyses, for the type specimen is only in very young 
bud, with the corolla not even exserted from the calyx. So far as the specimen 
goes, it agrees with Secamone platystigma, K. Schum., but further material is 
required to make the identification certain,

climbing. Leaves spreading, coriaceous, glabrous ; petiole 2-3 lin. long;

bracts 4 lin. long, ovate, acute or obtuse; pedicels }—1 lin. long, usu ally 
with 1-3 bracteoles. Sepals elliptic-ovate, obtuse. Corolla 1-14 lin. in

greenish. Coronal-lobes minute, compressed, deltoid-subulate, incurved
