Widely distributed through tropical Asia, also in N.E. Australia and Mada- 
gascar. The unpitted form which corresponds to HackeFs variety hcenkeanus 
of Andropogon intermedins (A. Haenkei, J.S. Presl in C.B. Presl, Reliq. Heenk. i.

in continental Africa^ \ 
2. A. radicans^SS^. Perennial ; rhizome very short, innova- 
tions extra- and intra- vaginal ; cataphylls glabrous. Culms slender, 
terete, 3-6-noded, erect or ascending or prostrate and then send- 
ing up bunches of short leafy shoots and culms, sometimes also 
rooting at the nodes, if erect usually simple or sparingly branched, 
more or less channelled on the side facing the branches. Leaf- 
sheaths of the innovation-shoots more or less compressed and keeled, 
short, all others terete, glabrous, smooth, bearded at the nodes or 
some of the nodes (particularly the upper) beardless ; ligules very 
short, truncate, ciliolate ; blades linear, gradually attenuated to a 
fine point, slightly or not at all contracted at the base, of innova- 
tions short, of culms up to 3 in. by 1 J — 2 lin., glaucescent, glabrous 
or sparingly hairy with minutely tubercle-based hairs, margins 
smooth except towards the tips, midrib slender, lateral nerves fine, 
2-3 on each side. Panicle subdigitate, up to 3 in. long ; primary 
axis filiform, J-l in. long, glabrous ; branches opposite or solitary, 
naked for 2-3 lin., simple, glabrous, smooth. Bacemes few to 9, 
slightly arching, up to almost 2 in. long, greyish- villous ; joints and 
pedicels very similar, 1 lin. long, ciliate, cilia gradually longer up- 
wards, the uppermost of the pedicels almost 1 lin. long. Sessile 
spikelet pale, linear-oblong, up to 2 lin. long, including the small 
shortly bearded callus. Glumes equal ; lower minutely truncate, 
slightly concave on the back, thinly chartaceous-membranous, hairy 
towards the base and somewhat higher up on the sides, otherwise 
glabrous, always unpitted, intracarinal nerves about 7, very faint, 
keels rigidly ciliolate upwards ; upper glume lanceolate, acute, 3- 
nerved, ciliolate upwards. Valve of lower floret slightly shorter than 
the glumes, oblong, subacute, hyaline ; awn of upper floret including 
the stipes 5-9 lin. long, column brown, bristle yellowish. Anthers 
1-1 J lin. long. Pedicelled spikelets $ or neuter, linear, subacute, 
as long as the sessile or shorter, slightly darker. Glumes equal or 
the upper shorter, lower glabrous, about 9-nerved, upper 3-nerved. 
Valve if present like that of the lower floret of the sessile spikelet. —
