Hairs of joint as long as or only slightly longer 
than the short cilia of the sessile spikelet ; 
pedicelled spikelet mucronate or aristulate ... 5. E. Pobeguinii. 
Culms branched upwards ; flowering branches 
usually 2-nate, laterally exserted from spathe- 
like sheaths ; sessile spikelets 3 lin. long ; hairs 
of joints slightly longer than the short cilia of 
the sessile spikelet ... 6. E. tenax. 
Culms simple or very sparingly branched and then 
the branches solitary, distant. 
Racemes glabrous ... ... ... ... ... 7. E. Welwitschii. 
Racemes very villous from the long hairs of the 
joints or all over. 7 
Culms singly, with short bladeless cataphylls at — f 
the base, many-noded ; hairs of joints and 
cilia of sessile spikelet 1-2 lin. long, back 
of lower glume glabrous ... ... ... 8. E. Hensii. 
Culms fascicled, with intravaginal innovation 
shoots, without short bladeless cataphylls 
at the base. 
Spikelets long, villous all over, the hairs up 
to 3 lin. long, keels of lower glume indis- 
tinct, mucros hidden by the hairs ... 9. E. Chevalieri. 
Sessile spikelet glabrous or pubescent on the 
back of the distinctly 2 -keeled lower 
glume, or if villous the hairs not hiding 
the mucros ; pedicelled spikelet spar- 
ingly hairy to glabrous, excepting the 
short cilia 10. E. argenteus. 
1. E. hirtifolius, Hack, in DC. Monogr. Phan. vi. 341. Perennial, 
densely csespitose, innovation shoots intravaginal, more or less 
compressed below. Culms erect, about 1J ft. high, simple or rarely 
with a flowering branch, terete, bearded close below the nodes, 
otherwise glabrous, smooth, 3-4-noded, internodes mostly long ex- 
serted. Basal leaf-sheaths lax, covered with silky appressed hairs, 
at length somewhat glabrescent, long-persistent, those of the inno- 
vation shoots more or less compressed, the upper terete, tight 
unless they enclose a flowering shoot, hairy towards the mouth, 
otherwise mostly glabrous, the uppermost bladeless ; ligules very 
short, membranous, densely ciliate ; blades linear, shortly acute or 
subacute, 2-4 in. long, 1 'to over 1 J lin. wide, or the upper shorter, 
folded in vernation, then flat, more or less hirsute, sometimes very 
densely so, rough along the margins particularly upwards, lateral 
nerves 3-4 on each side, prominent below. Racemes 1J-2J in. 
long, straight or curved, peduncled, the terminal finally more or 
less and sometimes long exserted from the subspathaceous support- 
ing sheath, villous, greenish, tinged with purple. Rhachis some- 
what tough unless quite mature ; joints linear, up to 2 lin. long, 
densely villous, upper hairs up to 2 lin. long, disarticulating 
obliquely ; pedicels similar, slender, with long hairs only on one
