Mozamb. Dist. German East Africa: Donde, gregarious, Busse ! 
I prefer to treat this form as a variety of LZ. Kirkii, which it :esembles in 
foliage and flowers. The peculiar habit, which is very uniform over a large area as 
Dr. Busse tells me and as his excellent photographs show, may very well be due to 
the conditions of the habitat—a dry region covered with bush and open Leguminosae 
woods—just as Z. Heudelotii assumes a similar facies under similar conditions on 
the dry laterite plateaux of French Guinea and Sierra Leone. 
25. L. parvifolia, X. Schwm. in Engl. Jahrb. xv. 409, ¢. xii. C. 
A much-branched climbing shrub with tendrils (modified inflorescences) 
from the branch-forks; young branches more or less rusty-villous, at 
length usually glabrescent, reddish-brown dotted with whitish lenticels. 
Leaves small, oblong to lanceolate, subacuminate to subobtuse (rarely 
subacute) at the base, #1? in. long, 6-7 lin. broad, coriaceous, rusty- 
villous in bud, soon glabrescent except the midrib and margins, glossy 
above ; midrib very slender and flat above, much stouter and prominent 
below ; secondary nerves subhorizontal, about 10-12 on each side, very 
faint on both sides, and like the extremely delicate network of the 
veins not or scarcely raised on either side; petiole more or less villous, 
1 lin. long. Corymbs small, dense, subsessile or shortly peduncled ; 
peduncles and lower bracts rusty-villous ; upper bracts scarious and 
almost glabrous ; pedicels very short, puberulous. Calyx about 14 lin. 
long ; sepals broad-ovate-oblong, obtuse or subtruncate, keeled, brown, 
subscarious, glossy, fulvo-ciliate along the margins and the keel, other- 
wise almost glabrous. Corolla pale yellow or white; tube cylindric 
below the middle, then inflated and rather suddenly constricted close to 
the mouth, 2—23 lin. long, very minutely and densely rusty-tomentose 
in the upper %; pubescent within except at the base; lobes linear- 
oblong, subacute, as long as the tube, minutely fulvo-velvety without, 
mouth very narrow, very minutely pubescent. Stamens in the upper } 
of the tube ; anthers linear-ovate, acute, reaching almost to the mouth. 
Ovary ovoid, glabrous at the base, top densely rusty-villous ; style and 
stigma 1 lin. long, the latter cylindric from a thickened base, bifid. 
Fruit like a small orange, 1-2 in. in diam., greenish-purple outside, 
rind smooth, thick, with a layer of sclerenchymatous nodules ; seeds up 
to 7 lin. long.—Dewévre, Caoutch. Afr. Monogr. Landolph. 52 ;
