erticillata.

=Setaria glauca, _Beauv._=

This is a tufted annual grass. Stems are slender, simple or branched,
erect or ascending.

The _leaf-sheaths_ are glabrous. _Nodes_ are glabrous and sometimes the
lower are rooting. The _ligule_ is a fringe of long hairs.

The _leaf-blades_ are lanceolate-linear, flat, finely acuminate, with a
rounded base and very finely and minutely serrate margin, glabrous on
both the surfaces or occasionally sparsely hairy on the upper surface
and varying in length from 4 to 12 inches or more, and in breadth from
1/4 to 1/3 inch.

The _inflorescence_ is a cylindric, densely flowered, spike-like raceme,
1 to 4 inches long, usually yellow, rarely purplish or pale green, the
bristles of involucels vary from six to twelve and are pale or reddish
brown, 1/6 to 1/3 inch long with fine erect or spreading barbs.

The _spikelets_ are numerous and are very closely set along the rachis
of the inflorescence, 1/8 inch long, glabrous and ellipsoidal.

There are four _glumes_ in the spikelet. The _first glume_ is less than
half the length of the third glume, broadly ovate, hyaline, 3-nerved.
The _second glume_ is a little longer than the first but shorter than
the third, broadly ovate or suborbicular, hyaline, 5-nerved. The _third
glume_ is longer than the second, as long as the fourth, membranous and
5-nerved, paleate, empty or with stamens. The _fourth glume_ is
coriaceous, broadly elliptic, obtuse, dorsally convex, transversely
rugose, pale. The _anthers_ are orange and the _styles_ purple.

This is a fairly common grass especially in cultivated ground all over
the Presidency, but not very widely distributed. Cattle are fond of this
grass.

_Distribution._--Throughout India.

=Setaria intermedia, _R. & S._=

This is an annual with straggling, slender, erect or ascending stems, 2
to 3 feet long.

The _leaf-sheath_ is glabrous, keeled, with the margins ciliate with
long hairs. The _ligule_ is a fringe of close set long hairs. The
_nodes_ are glabrous and the lower rooting.

The _leaf-blade_ is linear-lanceolate, narrowed towards the base, finely
acuminate, with fine hairs scattered on both the surfaces and with
numerous long hairs
