firmly herbaceous, quite glabrous and smooth, with short truncate 
shoulders at the mouth, closely striate, preceding sheath (imperfectly 
preserved) similar, passing straight into the blade ; ligules mem- 
branous, very short, truncate ; blades linear from an equally wide 
base, tapering to a slightly callous point, the uppermost 1-2 in. by 
1-J lin. (when flattened out), the preceding up to 6 in. by 3 lin., flat 
or convolute (at least upwards), somewhat plump, bright green,

here and there slightly looser, so as to expose the axis, frequently 
with more or less arrested spikelets among the perfect, particularly 
downwards ; pedicels very short, very sparingly puberulous or 
glabrous, smooth, tips discoid. Spikelets (perfect) broad-ovate, 
somewhat oblique and laterally compressed, not gaping, acutely
