Mozaxnb. Dist. German East Africa : Donde, gregarious, JBusse ! 



I prefer to treat this form as a variety of L. Kirkii, which it leseiiibles 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 Leguminosse 

 woods— just as L. Heudelotii assumes a similar facies under similar conditions on 

 the dry laterite plateaux" of French Guinea and Sierra Leone.

 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.

 subacute) at the base, |-1| in. long, 6-7 Hn. 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 ped uncled ; 

 peduncles and lower bracts rusty-villous ; upper bracts scarious and 

 almost glabrous ; pedicels very short, puberulous. Calyx about 1^ lin. 

 long; sepals broad- ovate-oblocg, 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, 2-2J 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 nouth. 

 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,
