nate, one of each pair usually sessile or subsessile and more or less 
rounded at the base, the other shortly petioled and acute or subacute at 
the base, those of each pair equal, or one of them much smaller, the 
larger leaves 4—6 in. long, 14-2 in. long ; secondary nerves 8-10; veins 
inconspicuous. Inflorescences subcorymbose, few-flowered, minutely 
bracteate, much shorter than the leaves, on very slender peduncles up 
to 1 in. long; pedicels up to 3 lin. long. Calyx deeply 5-partite, 
} lin. long; segments rotundate, sparingly and minutely ciliolate, the 
inner with 1 or 2 minute glands inside the base. Corolla yellowish, 
with red spots in the centre; tube cylindric from an ovoid base, 2 lin. 
long ; lobes broad, obovate, shorter than the tube. Stamens inserted 
at the middle; anthers over 1 lin. long, reaching to the mouth.—

at the base, 34-6 in. long, 3-1} in. broad, membranous; secondary 
nerves 6-8 on each side. Inflorescences geminate, terminal, shortly

This is, no doubt, a species of Tabernanthe, as K. Schumann himself has pointed 
out (Engl. & Prantl, Pflanzenfam. iv. ii. 146), and may be identical with one, of 
the species described above. 
18. PTEROTABERNA, Stapf. 
Calyx small, subherbaceous ; sepals 5, ovate, with several small, 
flat glands inside the base. Corolla small, salver-shaped ; tube cylindric, 
slightly widened in the upper third, thin, naked at the mouth ; Jobes 
overlapping to the left, inflexed in bud, oblique. Stamens in the widened 
part of the corolla-tube, erect; filaments very short, distinct, scarcely 
decurrent ; anthers linear-oblong, acute, minutely and acutely 2-lobed 
at the base; anther-cells polliniferous and dehiscent to the base of the 
apiculate lobes. Disc 0. Ovary apocarpous ; carpels 2, slightly coherent, 
lanceolate-ovoid ; style filiform ; stigma capitate, placed about the middle 
of the corolla-tube and distant from the anthers, not apiculate, slightly 
viscous ; ovules about 20 in each cell, approximately 4-seriate. Mericarps 
im pairs, or solitary by abortion, subbaccate, ovoid, rather flat on the face, 
with 3 narrow wings (2 lateral, 1 dorsal) ; pericarp thin, subcrustaceous ;
