Also in Arabia and in India from Afghanistan to Ceylon and Behar. Intro- 
duced in Mauritius and Jamaica. A valuable fodder in India for grazing as well 
as for stacking, very common and characteristic in cattle compounds. The 
“ sour grass ” of the West Indies, usually referred to Andropogon pertusus is 
not this species, but partly Amphilophis feracidula, Stapf, and partly A. inter- 
media (?), var. acidula^ Stapf. ^ 
5. A. insculpta^Siapyf Perennial ; rhizome very short, innova- 
tions intra- and extra- vaginal ; cataphylls glabrous. Culms slender, 
to over 3 ft. high, terete, many-noded, erect or geniculate, ascending, 
lower internodes often much lengthened and wiry, upper easily 
compressible and often deeply hollowed on the side facing the sub- 
tending leaf. Leaf-sheaths of the innovation-shoots more or less 
compressed and keeled, all others terete, glabrous, sometimes 
bearded from the mouth, smooth, long-bearded from the nodes, 
shorter than the internodes ; ligules short and truncate or broad- 
ovate and up to 1J lin. long, scarious ; blades linear, long-attenuated 
to a fine point, rounded and distinctly contracted at the base, of 
innovations short, of culms up to over 9 in. by 1^ — 2A lin., pale green 
to glaucous, usually glabrous, rarely pubescent or sparingly beset 
with long fine hairs, sometimes rough all over beneath, margins smooth 
except towards the tips, midrib slender, lateral nerves fine, 3 on each 
side. Panicle subdigitate, 3-4 in. long ; primary axis filiform, f to 
1J in. long, finely hairy at the branch-axils, branches opposite or 
solitary, sometimes in whorls of 3, naked for 2J-4 lin., simple, 
glabrous, smooth. Racemes 6 to 12, rarely more, usually over 2 in. 
long, flexuous, olive-green, variously flushed with dull purple, 
slightly silvery- villous ; joints and pedicels very similar, 1J lin. 
long, ciliate, cilia gradually longer upwards, uppermost 1J lin. long.

with dull purple or violet, including the short bearded callus 2-2|
