II. STOMATOSTEMMA, N. E. Br. 
Calyx 5-partite. Corolla-tube broadly campanulate ; lobes over- 
lapping in bud. Corona of 5 fleshy clavate lobes inserted in the 
sinuses between the corolla-lobes. Stamens inserted near the base 
of the corolla-tube ; filaments free; anthers united at their base to 
the dilated part of the style, connivent in a cone, triangular, with 
the connective produced into a fleshy apiculus, glabrous. Pollen 
granular. Pollen-carriers with the margins inrolled so as to nearly 
form an oblique-mouthed tube, broadly ovate when flattened out, 
grooved down the back. Style shortly conical at the apex, shorter 
than the anthers. Follicles and seeds not seen. 
A climbing or bushy shrub, with milky juice; leaves opposite; flowers of 
moderate size, in few-flowered cymes, axillary (often from both axils) and 
terminal, sometimes forming an elongated terminal narrow panicle, sometimes 
somewhat corymbose. 
Distris. Species 1, also in Tropical Africa. 
I have separated this plant from Cryptolepis chiefly on account of the 
position of the corona-lobes, which are much more distant from the stamens 
than they are in Cryptolepis and occupy the same position that the sinus- 
pockets do in that genus, so that they probably represent the same organs, whilst 
the corona-lobes which arise from the middle of the corolla-tube in Cryptolepis 
are not represented in Stomatostemma, ‘The corolla also differs from that of 
Cryptolepis in being more inflated and more obtuse when in bud, and has a 
much broader tube and broader lobes than in any species of that genus. The 
name is formed from oroua (a mouth) and orexua (a crown), in allusion to the 
position of the corona at the mouth of the corolla-tube.

pedicels 13—2 lin. long, with two minute bracts at about the middle ; 
sepals 1-1} lin. long, oyate or ovate-oblong, obtuse ; buds ellipsoid ;

dusted with purple-brown along the middle of the lobes and entirely
