obtuse, sparingly eiliolate, awn 8-5-12-7 mm. long. Anthers 0-5 mm. long, deep 

 red or purple. Grain sublinear, tapering upwards, Pedicelled spikelet reduced 

 to a minute glume,, often passing indistinctly into the pedicel and produced into 

 a bristle-like awn, about 4 - 2 mm. long. 



Locality : S. M. Country : Badami (Talbot 2930 !). 



Distribution : Widely distributed throughout the tiopics,

After the restoration of HackePs subgenera to the rank of genera, the general 

 characters of Andropogon itself must be modified in many ways : 



Mostly perennial grasses of various habit. Spikelets 2-nate, the sessile and 

 pedicelled differing from one another in sex and more or less heteromorphous, all 

 pairs similar, or if the lowest sessile spikelet male or imperfect then resemb- 

 ling the others. Spikes (spiciform racemes) many-jointed, fragile, paired (very 

 rarely solitary) or corymbose (digitate or subdigitate) on terminal peduncles, 

 embraced below by a spathe-like leaf (spatheole), frequently 2 or more pairs 

 with their spathes subtended by a common spathe and so on to more compo- 

 site branching, the whole forming a false panicle ; the sessile spikelets falling 

 with the contiguous joint and the accompanying pedicel ; joints and pedicels 

 filiform or thickened upwards and then the tips frequently more or less cupular 

 orauricled. Sessile spikelets dors ally or laterally compressed, nearly always 

 awned ; callus short, mostly quite obtuse, shortly bearded. Involucral glumes 

 equal or subequal, subcoriaceous to membranous, lower flat or concave or 

 channeled on the back, with at least from the middle upwards sharply inflexed 

 margins, 2-keeled ; upper more or less boat-shaped, keeled upwards, 3-1-nerved, 

 sometimes aristulate. Floral glumes ciliate or eiliolate, rarely glabrous, lower 

 hyaline, 2-nerved, upper 2-fid or 2-dentate, hyaline or firmer and some- 

 times substipitiform below the insertion of the awn. Pale a hyaline nerveless 

 scale or 0. Lodicules 2, minute, glabrous. Stamens 3. Stigmas laterally 

 exserted ; styles terminal. Grain narrowly lanceolate to oblong in outline, 

 subterete to planoconvex ; embryo about half the length of the grain. Pedicel- 

 led spikelets often very different from the sessile in shape and less so in size, 

 always more or less compressed dorsally, never concave or channelled on the 

 back, sometimes reduced and then of ten small or quite suppressed. Involucral 

 glumes herbaceous-chartaceous to membranous, the lower muticous or very 

 rarely aristulate. Floral glumes, if present, hyaline, ciliate, muticous. 



Species about 100, mostly in the tropics of both hemispheres.

37. Cymbopogon, Spreng.; Stapf in Prain Fl. Trop. Afr. ix, 265. 



Perennial, densely tufted and usually aromatic grasses. Leaves often very 

 coarse. Panicles frequently much compound and contracted, spatbeate. 

 Spikelets 2-nate, those of each pair differing in sex and more or less in shape — 

 except those of lowest pair of the lower or of both racemes which are homoga- 

 mous (male or neuter) — one sessile, the other pedicelled on the articulate fragile 

 rhachis of many-jointed paired racemes, terminating the culms and their 

 branches ; raceme-pairs supported by a spatheole, collected into often decom- 

 pound or supra-decompound spatheate panicle ; the fertile spikelets falling with 

 the contiguous joint and the accompanying pedicel ; joints and pedicels filiform
