The var. major and the typical form of D. uniglumis represent apparently 
climatic or edaphic modifications. Adamson’s specimen is intermediate, 
combining the lower stature and shorter leaves of the type with the long panicle 
and the more conious indumentum of var. major. X/). diagonalis, Stapf ( Panicum 
diagonale, vars. genuinum and robustius, Hack, in Durand & Schinz, Consp. FI. 
Afr. v. 746, 747) is confined to South Africa and characterized by considerably 
larger spikelets (1 1 lin.). 
44. D. minutiflor Annual, about 1J-2 ft. high. Culms 
in scanty fascicles or solitary, erect or ascending from a short some- 
times rooting base, very slender, simple or more often sparingly 
branched below, 4-6-noded, glabrous, terete. Leaf-sheaths rather 
loose, glabrous or the lowest more or less shortly hirsute, striate 
and the lower slightly keeled upwards ; ligules very short, scarious, 
truncate, glabrous, brown ; blades linear from an equally broad 
base, tapering to a slender fine point, 6-12 in. by 2-3 lin., flat, 
flaccid, glabrous, green, very slightly rough, at least on the upper 
side and along the margins, midrib very slender, primary lateral 
nerves very fine, about 3 on each side. Bacemes usually over 10
