panicles, with 12-15 almost glabrous branches from the lowest node and chest- 
nut-brown fruits (subvar. verticillata, Schum. he. 46). Probably a form of

Grain dull white. 
Mozambique Distr. German East Africa : Masailand ; Meatu, Baumann ; 
Speke Gulf ; Katoto, Baumann ; Urundi ; Elmatau, Baumann. 
Very likely a form of 8. caudatum. A specimen from Ondonga ( Schinz !),

Caffrorum (which see). 
7. A. S., var. calcareus, Busse & Pilger in Engl. Jahrb. xxxii. 188. 
Panicle very dense, lanceolate in outline, about 8 in. long ; rhachis 
stout ; branches short, erect. Sessile spikelets crowded. Glumes 
roundish, minutely toothed at the tip, orange or brown, glabrous, 
or pubescent on the sides. Grain exceeding the tightly appressed 
glumes, chalk- white, 2 lin. by If lin. 
Mozambique Distr. German East Africa : Ugogo ; Hindi, Busse, 276, 276a. 
Vernacular name “ Icigegu.” Probably a form of 8. caudatum.

187. Panicle pyramidal, lax, about 1 ft. long ; branches slender, 
erect, nodding, the lower 4-6 in. long. Sessile spikelets globose- 
ovoid, more or less black when mature, glossy. Glumes rather

Busse, 1881. 
Busse’ s specimen is described as having a more contracted panicle with 
stiffer branches and shorter glumes.
