 long. Empty glume 1, situated at a short distance below the flowering 

 glume, encircling the flowering-glume and palea, and shorter than 

 them, oblong-lanceolate, with a linear-lanceolate small rudimentary leaf 

 (or microphyll), chartaceo-membranaceous, ciliated and more or less 

 pubescent towards the margin, many-nerved. Flowering-glume convoluto- 

 cylindrical, lanceolate, acuminate with a hispid-spinescent tip, rigidly 

 chartaceous, viridescent, piloso-pubescent, about 10-11-nerved, the transverse 

 venules very delicate and loose. Palea slightly shorter than the 

 flowering-glume, convoluto-linear-cylindrical, linear-lanceolate, attenuated 

 above, bifid with scabro-his[)id spinescent lobules at the apex, chartace- 

 ous, greenish, thinly pubescent on the dorsal surface, more or less 

 closely and obtusely bi-carinate on the back, forming a very shallow 

 and narrow groove between the carina3, about 11-nerved, the transverse 

 venules very delicate and loose. Lodicula3 3, lanceolate, acuminate, 

 6|-7mm. long, thinly membranaceous, minutely ciliated on the margin, very 

 thinly pubescent in the outside ; vertically pluri-nervate below. Stamens 3, 

 exserted ; filament long, filiform, glabrous ; anther linear, bifid at the base 

 and usually acutish at the apex, pale yellow. Pistil nearly 2 cm. long ;
