30 Lxxxiv. APOCYNACE^ (stapf). [Vcihadenia. 



from all the species of this genus in the large, persistent, ultimately reflexed 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 

 I)e Wildeman's description. 



1. V. Laurentiiy Stapf. A perfectly glabrous, semiscandent 

 shrub ; young branches shining, very rough from numerous pale brown 

 lenticels. Leaves obovate-elliptic or obovate, very shortly acuminate 

 or obtuse, rounded or subcordate at the base, 3-6 in. long, 1 J-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, S-'d^ 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 sulcate on the back 

 in bud. ^ Anthers Ij lin. long. Fruit Ij-lf in. diam. (mature?) —

Calyx f-lj lin. long (or 2J-3 lin. in § Mesaiidrcecia) ; sepals 5, 

 •free or connate below, usually more or less ovate, hairy or glabrous, 

 eglandular. Corolla salver-shaped ; tube moreor less cylindric, H-12 lin. 

 lent', 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 ^-2 calyx-lengths 

 in §§ Vahea a,nd Mesandrcecia); 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 Mesandroecia) ; 

 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, rai^ely very close ; axillary stipules ; axillary 

 glands minute, obscure, or (in § Ancylobotrys) subulate to filiform. 

 Flowers small to middle-sized, rarely 2 in. long in bud, pedicelled or
