PLATE 496. 



ANDBOPOGON TRAXSVAALEXSIS, Stapf. (Fl. Cap., Vol. VII., p. 363). 



Xat. Order Grratnioete. 



PERENNIAL, tufted. CULMS erect, subgeniculate, simple, slender, over :> feet 

 long, terete, glabrous, 5-noded below the panicle ; sheaths tight, glabrous, the loircr 

 firm, short, persistent, keeled above, fugaciously and adpressedly hairy, the ///t}tet' 

 much shorter than the internodes ; ligules membranous, rounded, up to 1 line long ; 

 blades narrow, linear, tapering to a long setaceous point, up to 1 foot, by 1 line. 

 flat or convolute above, rigid, glabrous, scabrid in the upper part. 



PANICLE consisting of about 12 erect 2-3-nate simple, long filiform branches 

 from long narrow spathiform sheaths bearing filiform or setaceous blades ; spathes 

 finely linear, acute, 2 to 2J inches long, glabrous, reddish ; common peduncles filiform. 

 exserted near the tip of the spathe, the exserted part flexnous. -_ to 1 inch long. 

 pubescent and bearded with long tubercle-based hairs, dark purple. Racemes con- 

 tiguous, (5 to 8 lines long, one sessile, the other on a fugaciously hairy purple 

 peduncle, joints filiform, obliquely truncate, 1 line long, dark purple, densely ciliate 

 with rigid white hairs ; pedicel very similar, usually produced into a fine subulate 

 membranous appendage, facing the upper glume. 



SPIKELETS, sessile ones 2 to 4 in each raceme, perfect with the exception of the 

 lowest, which is male like the pedicelled : perfect spikelets linear-oblong, 2 lines long. 

 purple, hairy, callus acute, bearded, up to J line long. 



GLUMES, lower subchartaceous, truncate, dorsally flattened, sometimes shallowly 

 pitted, intracarinal nerves 5, prominent above almost throughout or evanescent below. 

 hairs scattered all over or mainly near upper margins ; upper obtuse, 3-nerved, hairy 

 above ; loicer valve almost equalling the glumes, linear, obtuse, sub-2-nerved, scantily 

 ciliate ; upper shortly 2-lobed, ciliate, 3-nerved near the base, awn about 1 inch long, 

 slender, pubescent and kneed below the middle ; pale ; male spikelets narrowly 

 lanceolate, up to 3-3 lines long, muticous, hairy or lowest glabrous, 7-9-nerved, 

 keels scantily and rigidly ciliate above ; upper acute, hairy or glabrous, long ciliate : 

 valves almost equalling the glumes, ciliate, lower 3, upper 1 -nerved. 



Intermediate between A. Dregeanus and A. filipcndulus.
