nearly 3 in. long; leaf-blades 11 to 4 in. long by 1 to 2 lines 
broad. Panicles 5 to 7} in. long, generally between } and 2 in. 
in diameter, branches rarely reaching 1 in. in length, ascending, 
the greater number bearing only 3 or 2 spikelets, reduced near 
the top of the rhachis to single spikelets. Spikelets 3 to 5 lines 
long, 3 or barely 3 lines broad at the base; barren glumes some- 
times tinged with purple, 14 to 2 lines long ; fertile 12 to 13 line 
long and as broad; pale 13 to 14 line long by about 1} line broad ; 
anthers pale brown, a little over 3 line long. 
Allied to EZ. superba Wawr, & Peyr. but with considerable 
differences the most striking of which are the sessile spikelets, 
acute glumes, broader pales, and hairy leaves. 
Huitia.—Plentiful in sandy pastures grown with short thickets by 
edges of woods at Monino; April 1860. No. 7506. 
39. E. flavicans Welw. ms. in herb. 
A very elegant grass, annual, cespitose, culms slender, erect. 
from a spreading ascending base, with numerous short internodes, 
geniculate, profusely branched at the lower nodes, internodes 
terete or subcompressed, glabrous, the lower enveloped by the 
subcompressed leaf-sheaths, the upper exceeding them; sheaths 
with pilose edges and mouth, the lower sparsely scabridulously 
pilose in the upper part ; ligule a very short dense line of hairs ; 
blades flat, narrowly linear-lanceolate, acuminate, rigidulous, 
scabridulously pilose, especially on the lower face on the 5 to 7 
prominent veins; panicle narrowly cylindrical, closely resembling 
that of #. cylindrispica, the glabrous rhachis bearing short. 
reduced lateral branches distichously arranged in 2 longitudinal 
furrows ; spikelets compressed, spreading, yellowish-green, lanceo- 
late, or ovate-lanceolate, densely 10- to 17-flowered, rhachis jointed. 
below each flower; barren glumes equal in length and similar 
to the fertile but narrower and acuminate, ovate, imperfectly 
3-nerved, keel strong and scabridulous in the upper i to 2, the 
upper broader and a shade longer; fertile glumes orbicular-ovate, 
shortly acute, lateral nerves prominent, keeled and minutely 
scabridulous above the middle; pale slightly shorter, narrowly 
obovate when flattened, truncate, keels membranously winged ; 
anthers yellowish; grain reddish-brown, reticulated, ellipsoidal, 
laterally subcompressed with prominent basilateral hilum. 
Described by Welwitsch as a very elegant plant when alive, 
remarkable not only by its yellowish spikelets, but also its 
greenish-yellow leaves and culms. Plants 14 to 16 in. high, 
internodes increasing in length upwards from + to 1 to 2} in., 
from } to over 3 line thick; ligule barely } line long ; leaves 1 to 
22 in. long by I line or a little more broad. Panicle 3} to 53 in. 
long, by + to # in. across, sometimes tapering slightly upwards ; 
lowest branch to # in. long, often with 5 spikelets, becoming 
reduced above to 3, 2 and finally single spikelets. Spikelets 3 to 
4 lines long by 2 lines or less in breadth; barren and fertile 
glumes 1 line long ; anthers a good 3 line; grain barely 3 line.
