fertile glume hyaline, truncately ovate, plicate, shortly mucronate, 
nerves 3, hairy on the back, margins narrow, incurved at the lateral 
nerves; pale truncately lanceolate, apex retuse, nerves approxi- 
mate, hairy on back; anthers 3, pale yellow; ovary glabrous. 
Fully developed plants 81 in. high, densely leaved, culm-bases 
11 to 2 in. high, the sheaths short, compressed, and except the 
outermost hidden by those below, not exceeding 2 lines long ; 
blades 3 to ? in. long, the older ones becoming flattened and 1? 
line broad, cauline leaves linear, plicate, with shortly pungent 
apex, rarely exceeding 4 in long; fully grown flowering culms. 
7 in, above the leaves. Spikes reaching 22 in., scarcely exceeding 
4 line in width, rhachis glabrous. Spikelets whitish green in 
dried specimens; gl. I. 14 line long, whitish with green nerve, 
gl. II. slightly longer (scarcely 12 line) fertile gl. 1 line, pale 
slightly shorter, anthers a good 4 line. 
The spike is that of WM. setacea, but the species is distinguished 
by its broader ensiform leaves, which give it a very distinct habit.
