extensive associations. / It is the Rooi grass of South Africa and like its Aus- 
tralian representative YT/iemerfa australis: Stapi (Anthistiria australis, R. Br„), 
a most valuable fodder grass (see Transvaal Agric. Journ. iii. 287, and Medley 
Wood, Natal Plants, ii. t. 133).

Culms erect or more often geniculate-ascending with stilt roots from 
the lower nodes, slender to stout (almost 3 lin. in diam.), terete, 
glabrous, often glaucous-pruinose below the nodes, 5-7-noded and 
simple below the panicle or here and there with additional flowering 
branches from the lower nodes, sometimes trailing among shrubs 
and other plants and then frequently many feet long. Leaf-sheaths 
compressed and keeled (the lowest) or terete, tight and much shorter 
than the internodes (the upper of the culms), glabrous, smooth ; 
ligules membranous, glabrous, rounded, about 1 lin. long ; blades 
somewhat flaccid, folded in bud, soon flat, linear from a slightly 
rounded base, shortly acute, particularly the lower, or more or less 
tapering to a slender point, the basal short, the intermediate up to 
1 ft. long by 2-3 lin., green or slightly glaucous, glabrous on both 
sides or sparingly fimbriate with long fine tubercle-based hairs
