when dry. Corolla dirty whitish when dry, quite glabrous; tube sub- 
cylindric, slightly widened at or just below the middle, 4—4} lin. long ;

Stamens inserted just below the middle of the corolla-tube; anthers 
ovate-lanceolate, subacute, 1 lin. long. Ovary depressed-ovoid, 10— 
sulcate, glabrous; style and stigma about 1 lin. long; stigma shortly

This differs from Z. Buchananii in the slightly smaller leaves, the somewhat 
looser corymbs and larger flowers with proportionately longer corolla-lobes. These 
are much whiter when dry than in Z, Buchananii and more or less twisted instead 
of straight as in the latter. 
5. L. leonensis, Stapf. A scandent shrub with sensitive inflor- 
escences acting as tendrils; young branches rather stout, densely 
covered with a delicate fulvous tomentum, intermixed with short stiff 
spreading hairs which soon rub oft. Leaves obovate-oblong, abruptly 
and acutely acuminate, minutely cordate at the base, 6-7 in. long, 
about 3 in. broad, thinly coriaceous, densely fulvo-tomentose in bud, 
nearly glabrous when adult, dark brown above, reddish-brown below 
when dry; midrib and secondary nerves channelled above, prominent 
below ; secondary nerves about 6 on each side, rather oblique, almost. 
straight, connected by more or less conspicuous arches rather close to 
the margin ; transverse veins distinct, rather distant ; network of veins 
very delicate, faintly raised on both sides; petiole stout, 3 lin. long. 
Corymbs dense, many-flowered, at the ends of the remote divaricate or 
recurved short rather slender branches of long narrow peduncled 
panicles, lower parts of the panicle finely fulvo-tomentose, upper more 
or less minutely hirsute to glabrous; peduncle about 3 in. long, mode- 
rately stout ; rhachis up to 9 in. long; lower branches up to 14 in. 
long ; bracts minute, rounded, ciliate; pedicels glabrous, up to 14 lin. 
long, rather slender. Calyx 1} lin. long ; sepals ovate or oblong, obtuse, 
rigidly ciliolate, otherwise glabrous or almost so. Corolla glabrous 
without or with a few scattered hairs in the upper part; tube sub- 
cylindric, gradually and slightly widened from the base to a little above 
the lower third of its length, then much attenuated, over 10 lin. long; 
lobes ovate-oblong, obtuse, 4 lin. long. Stamens inserted about 3 lin. 
above the base; anthers oblong, acute, over 1 lin. long. Ovary shortly 
ovoid, glabrous, abruptly contracted into the style; style and stigma 
3} lin. long; the latter cylindric from a thicker base which exudes @ 
waxy substance.

6. L. senegalensis, Koischy & Peyr. Pl. Tinn. 31. A dense 
shrub up to 24 ft. high, or more commonly a strong climber, glabrous 
except the inflorescences; tendrils long, branched ; young branches pale 
or almost black when dry, dotted with minute lenticels. Leaves oblong,
