62 NEW SOMALI-LAND PLANTS. 
The genus Lasiostelma contains seven species—viz. L. Sandersoni 
Oliv. (Brachystelmavia natalensis Schlecht.), L. Gerrardi (B, Gerrardi 
Schlecht.), L. longifolium (B. longifolia Schlech t) L. macropetalum 
(B. snagereeasten Schlecht.), L. ramosissinum (B. ramosissimum 
Schlecht.), L. somalense, and L, subaphyllum ' (Brach ystelma sub- 
aphylium K. Sch.). 
As to its s affinity, our plant resembles most in habit L. sub- 
aphyllum, also from Somali-land; but it is very different in the 
shape of the petalt and the structure of the corona. The colour 
of the flowers in the specimen s hand i oie brown with dark

This has much the look of very diminutive forms of P. speciosus, 
but it is entirely different from that plant, e.g. in its saccate 
corollas with much narrower and, indeed, altogether diversely 
shaped tube, and dissimilar limb. Ju dging from the description, 
P. angustifolius Engl. has some points of resemblance to the new 
spocies, from which, however, among other points, its very slender 
corolla serves at once as a distinguishing feature. The well 
developed sac of P. saccatus is a noteworthy character.
