This differs from i. Btichananii in the slightly smaller leaves, the somewhat 

 looser corymbs and larger flowers with proportionately longer corolla-lobes. These 

 are much whiter wdicn dry than in L. Btichananii and more or less twisted instead 

 of straight as in the latter. 



f). L* leonensis, Stwpf. 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 off'. Leaves obovate-oblong, abruptly 

 and acutely acuminate, minutely cordate at the base, G-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 C 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 IJ in. 

 loi^ ; bracts minute, rounded, ciliate; pedicels glabrous, up to IJ lin. 

 long, rather slender. Calyx 1 J 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, gi^adually 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 a 

 waxy substance.
