30 LXXXIV. APOCYNACE# (STAPF). [ Vahadenia. 
from all the species of this genus in the large, persistent, ultimately retlexed or 
spreading sepals, the very numerous intracalycular glands, the stout, fleshy corolla 
and the woody pericarp. I have not seen any seeds, and state their number from 
De Wildeman’s description. 
1. V. Laurentii, Stapf. A perfectly glabrous, semiscandent 
shrub ; young branches shining, very rough from numerous pale brown 
lepticels. Leaves obovate-elliptic or obovate, very shortly acuminate 
or obtuse, rounded or subcordate at the base, 3-6 in. long, 14-2} in. 
broad, coriaceous with thickened margins, glossy on both sides, reddish- 
brown below when dry; midrib finely channelled above, prominent 
below ; secondary nerves about 8 on each side, oblique, conspicuously 
prominent below, finely channelled above, connected by bold sub- 
marginal arches, reticulation distinct below. Panicle glabrous; 
branches very rough; bracts broad, apiculate, up to 1 lin. long, 
ciliolate. Calyx quite glabrous, eciliolate ; sepals 4—5 lin. long, 3—3$ lin. 
broad, subcoriaceous, reddish-brown, spreading or reflexed in fruit. 
Corolla brownish-red when dry, glabrous ; tube 7-8 lin. long; lobes 10 
lin. long, 2 lin. broad, ciliate, fleshy, longitudinally suleate on the back 
in bud. Anthers 1} lin. long. Fruit 14-1? in. diam. (mature ?)—

Calyx }-1} lin. long (or 23-3 lin. in § Mesandrecia); sepals 5, 
free or connate below, usually more or less ovate, hairy or glabrous, 
eglandular. Corolla salver-shaped ; tube moreor less cylindric, 15-12 lin. 
long, slender or rather stout, widened and staminiferous near the base 
or mouth or between them without correlation to the length of the 
corolla, but usually just above the calyx (higher up by 4-2 calyx-lengths 
in $$ Vahea and Mesandrecia); mouth naked, sometimes much constricted 
by a callous ring; lobes 5, narrow or broad, overlapping to the left. 
Stamens included; anthers ovate to lanceolate, minutely 2-lobed at and 
dehiscing to the base. Disc 0. Ovary entire, hairy or glabrous, 1-celled ; 
placentas 2, parietal ; style filiform or subcolumnar, usually short to very 
short, or longer and very slender (in $$ Vahea and Mesandrecia) ; 
stigma at a level with the base of the anthers, conical from a slightly 
thickened base, 2-lobed ; ovules numerous, pluriseriate. Fruit a globose 
or pear-shaped berry, sometimes of large size. Seeds few or many, 
embedded in a juicy pulp, ovoid or oblong, smooth ; endosperm horny ; 
cotyledons foliaceous, very thin; radicle short.—Hairy or glabrous 
shrubs, often of large size, usually climbing by flagelliform hook- 
branched terminal or pseudo-axillary tendrils (modified inflorescences), 
or by sensitive inflorescences, rarely dwarf shrubs or undershrubs with 
partly herbaceous branches. Leaves opposite, of varying size ; secondary 
nerves usually distant, rarely very close; axillary stipules 0; axillary 
glands minute, obscure, or (in $ Ancylobotrys) subulate to filiform. 
Flowers small to middle-sized, rarely 2 in. long in bud, pedicelled or
