[ Eriochrysis . 
shining ; rhachis slender, terete, long-hairy, bearded at the nodes. 
Racemes 6-14, solitary or the lower 2-3-nate, J to almost 1 in. long, 
rather stout ; joints and pedicels stout, terete, 1-1 J lin. long, ciliate 
with fulvous hairs up to 3 lin. long. Sessile spikelet lanceolate, 
straw-coloured, 2-2 1 lin. long, enveloped by rigid hairs up to 3 lin. 
long. Glumes subequal ; lower chartaceous, entire, subobtuse, 
2-keeled and 4-nerved between the keels which are long-ciliate 
above the middle. Valve of lower floret 1^-1 f lin. long, lanceo- 
late ; of upper very small, ovate, nerveless, tips ciliate. Anthers 
1 lin. long. Grain obovoid-globose, \ lin. long. Pedicelled spike- 
let $, similar to the sessile but smaller (lj-lf lin. long), with more 
copious enveloping hairs. Anthers rudimentary, very minute. —

Spikelets all alike, 2-nate, one sessile, the other pedicelled on the 
articulate fragile rhachis of panicled racemes, the pedicelled falling 
from their pedicels, the sessile deciduous together with the contiguous 
joint of the rhachis and pedicel. Plorets 2 ; lower reduced to an 
empty valve ; upper $ . Glumes equal, often chartaceous to sub- 
coriaceous towards the base, membranous to subhyaline upwards ; 
lower with inflexed margins and in the sessile spikelet usually with 
an even number of nerves ; upper 1-, 3-, or 5-nerved. Valves hyaline ; 
upper with a terminal bristle-like usually straight awn, or mucronate 
or muticous or 0. Lodicles 2, cuneate. Stamens 3. Stigmas 
laterally exserted. Grain oblong to subglobose ; embryo short to 
half the length of the grain or more ; hilum basal. — Perennial, tall 
to very tall ; leaves various ; panicle large, often silvery-silky and 
showy ; spikelets usually surrounded by long silky hairs from 
the base. 
Species about 7, tropical or subtropical. 
Racemes up to 4 in. long ; hairs of the callus 2-3 times 
as long as the spikelet ; valve of the upper floret 
subulate or 0. 
Leaf-blades up to 5 lin. wide ; spikelets 2-3 lin. 
long, surrounded from the callus by hairs up to 
6 lin. long ; lower glume chartaceous and red- 
dish at the base, whitish and subhyaline above 1. S. spontaneum. 
Leaf-blades up to 2 in. wide ; spikelets lf-2 lin. 
long, surrounded from the callus by hairs up to 
5 lin. long ; lower glume subhyaline, slightly 
firmer at the base, whitish throughout. . . . . . 2. S. officinarum.
