PLATE 168. 



Setakia lindenbergiana, Stapf. (Fl. Cap. Vo\ VII., p. 422). 



Nat. Order Graraineee. 



Perennial. — Culms erect, simple or branched near the base, slender, 2 to 3 

 feet long, glabrous or pubescent and sometimes with long soft hairs near the 

 panicle, 5 or more noded with the lower internodes short and enclosed when simple. 

 Branches few-noded. Sheaths tight, keeled above, striate, glabrous or hairy to 

 hirsute, lower firm, persistent, often strongly compressed ; ligule a ciliate rim. 

 Blades linear or linear-lanceolate from a long attenuate base, tapering to a fine 

 point, 3 to 12 inches, by 1|^ to 6 lines, closely plicately folded when young, at 

 length opening out (folds 8 to 12), usually glabrous, scaberulous above. 



Panicle linear to oblong, usually almost spike-like, often interrupted or 

 lobed, dense or lax, 2 to (> inches long ; axis angular, pubescent ; branches alternate 

 or irregularly approximate, 2 to 12 lines long, filiform, wavy, puberulous, simple 

 or divided from near the base ; bristles solitary, fine, scaberulous, wavy, 1 to 5 

 lines long, terminating the branches and branchlets, or sometimes in fascicles at 

 the base of the branches or solitary at the base of the lower spikelets ; pedicels 

 very short, tips discoid. 



Spikelets ovate-oblong, acute, 1 to 1^ line long, glabrous, light green or 

 tinged with purple. 



Glumes membranous, broadly ovate, obtuse ; loiver 5 to sub-7-nerved, rather 

 less than half as long as the spikelet ; upper 7-nerved, equalling about f the length 

 of the spikelet. Florets, lower- male, equalling the spikelet ; valve membranous, 

 broadly elliptic, obtuse, 7-nerved ; pale subequal to the valve, with narrowly 

 winged keels. Perfect floret elliptic-oblong, acute, equalling the lower floret ; 

 valve subcoriaceous, 5-nerved, pallid or purplish, particularly upwards, 'finely and 

 closely transversely wrinkled. Anthers J line long. ■ 



Habitat : Natal. Inanda, 1800 feet alt , Wood 1419 ; in shady woods by the 

 Umgeni River, Krauss 130. 



Also in Cape Colony, Orange Eiver Qo\onj. and in Tropical East Africa.
