pedicels filiform, scabridulous ; spikelets 3 to 5 lines by about 

 1 line greatest width. Barren glumes ^l to 1 line and 1 to 1^ line 

 respectively ; fertile glumes about 1 line long by 5^ to f broad ; 

 anthei's barely 2 line ; grain barely i line. 



Near E. tenuifolia Hochst. but distinguished by the much 

 larger barren glumes, broader flowering glumes and weaker 

 broader pales.

12. E. andongensis Welw. ms. in herb. 



Perennial with a strong woody rhizome, culms strict, densely 

 csespitose, 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 Avhen 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, 1-nerved, the lower 

 lanceolate to ovate, acute, the upper about i longer, subacute, 

 keels scabridulous, reaching .\ to ^ up the back of the lowest 

 fertile glumes; fertile glumes ovate, cuspidate, lateral nerves 

 ceasing about i 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, ^, 1, 3, 15 (to the base of the inflorescence) in. respectively. 

 Leaves as long as the culm, l line acro.ss. The specimen includes 

 a young subspreading leaf-shoot about 15 in. high, the leaves of 

 which are mostly flattened from a plicate base, 4^ to 12 in. in 

 length by barely 1 line maximum breadth, the .sheaths are
