Landolphia. | APOCYNACEZ (Stapf). 493 
Hairy or glabrous shrubs, often of a large size, usually climbing by flagelli- 
form, 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 § Ancylobothrys) subulate to filiform. Flowers small to middle- 
sized, rarely 2 in. long in bud, pedicelled or sessile in few- or many-flowered 
corymbs at the ends of the branches (sometimes overtopped by barren shoots and 
then occasionally pseudo-axillary), or gathered in more or less elongate panicles at 
the ends of their distant branches which are (like the rhachis) sensitive, »nd act 
as hooks or tendrils. 
DistRiB. Species about 50, the others in tropieal Africa and the Mascarene 
Islands, In South Africa only the sections Ancylobothrys and Eulandolphia. 
§ 1. ANcyLoBotHRys. Flowers sessile in dense clusters on the ends of the 
branches of terminal, mostly elongate, more or less sensitive panicles ; calyx up 
to 1} lin. long, hairy all over. Corolla-tube 3-12 lin. long, slender, cylindric, 
slightly widened and staminiferous just above the calyx ; lobes 3-11 lin. long, 
ciliate along the outer edge. Ovary hairy; style not or very slightly exceeding 
the calyx. Fruit globose or obovoid, with a leathery rind, having no sclerenchy- 
matic layer ; endosperm smooth. 
Leaves elliptie or elliptic-oblong, 2}-44 in. by 1-2in... (1) petersiana. 
Leaves more or less oblong, $-24 in. by 4-1 in.: 
Leaves 13-24 in. by 3-1 in.; lateral nerves sub- 
oblique, 8-10 on each side; corolla in the mature 
bud up to 18 lin. long Be ba Si ; 
Leaves #-1} in. by 4-3 in.; lateral nerves spread- 
ing mere or less at right angles, 12-14 on each 
side ; corolla in the mature bud 11-12 lin. long... (3) capensis. 
§ 2. EULANDOLPHIA. Flowers many or few in dense terminal corymbs, 
rarely in elongated panicles. Calyx up to 2 lin. long, hairy or almost glabrous ; 
sepals usually very broad. Corolla-tube 14-3 lin. long, inflated and stamini- 
ferous between the middle and the mouth, rarely at the middle; lobes 14-3 lin. 
long, not ciliate. Ovary hairy or glabrous; style very short, not or scarcely 
exceeding the calyx. Fruit globose to pear-shaped, with a hard rind, having a — 
concentric sclerenchymatous layer.

1. L. petersiana (Dyer in Kew Report, 1880, 42); a scandent 
shrub with sensitive inflorescences acting as tendrils ; young branches 
minutely rusty-pubescent to tomentose, soon glabrescent, reddish or 
finally greyish-brown with numerous small lenticels ; leaves elliptic 
or elliptic-oblong, subacute or more commonly obtuse at both ends, 
3i~—41 in. long, 11-2 in. broad, coriaceous, loosely pubescent on both 
sides when quite young, soon glabrous, usually blackish and some- 
what glossy above when dry, pallid beneath; midrib channelled 
above, raised below; secondary nerves oblique, distinctly curved, 
6-8 (rarely 10) on each side, finely channelled above, distinctly 
raised below ; tertiary nerves more or less irregular and like the fine 
network of veins usually distinct, brown, scarcely raised ; marginal 
arches obscure ; petiole about 3 lin. long; panicle short or elongate, 
peduncled, bearing clusters of many sessile flowers at the ends of 
short spreading or recurved branches; branches or rhachis often 
acting as tendrils, finely rusty-pubescent or glabrescent all over; 
peduncle 1-4 in, long, slender; rhachis 1-1} in. long, lowest
