12. E. andongensis Welw. ms. in herb. 
Perennial with a strong woody rhizome, culms strict, densely 
cespitose, closely sheathed for a third of the distance from the 
base by the long chartaceous subterete sheaths, sheaths striate, 
sparsely pilose when young, ultimately glabrous except at the 
mouth; ligule a short membranous ridge; blade suberect, 
rigidulous, very long, narrow-linear, acuminate, becoming con- 
volute with subpungent apex, densely pilose on the upper face 
when young, becoming less pilose when convolute; inflorescence 
narrow cylindrical, interrupted, rhachis elongated, strong, scabrid, 
twisted, bearing numerous short, sessile, congested spikes ; spikelets 
12- to 18-flowered, compressed, linear-oblong to oblong-lanceolate, 
compact, olive-green, solitary or in pairs in the upper part of 
the inflorescence; barren glumes brown, l-nerved, the lower 
lanceolate to ovate, acute, the upper about 1 longer, subacute, 
keels scabridulous, reaching 3 to 2 up the back. of the lowest 
fertile glumes; fertile glumes ovate, cuspidate, lateral nerves 
ceasing about 4 from the apex, keels becoming stronger and 
minutely scabridulous above the middle and prolonged above into 
the short cusp; pale scarcely shorter, angularly curved, blunt, 
large, broadly elliptical when flattened, keels broad and scabridu- 
lous, inflexed margins broad. 
Flowering culm (including inflorescence) 27 in. long, internodes 
four, 3, 1, 3, 15 (to the base of the inflorescence) in. respectively. 
Leaves as long as the culm, 3 line across. The specimen includes 
a young subspreading leaf-shoot about 15 in. high, the leaves of 
which are mostly flattened from a plicate base, 42 to 12 in, in 
length by barely 1 line maximum breadth, the sheaths are
