Stolons long, densely clothed by lanceolate striate dirty-straw-colrd. scales. 
Stems 3 ft., trigonous, under panicle flattened biconvex. Basal leaves often as long 
as stem, hardly i in. broad; in their upper half very variable in form, sometimes 
xiphoid (i.e. flat thick in middle without a central nerve), sometimes 3—4-angular or 
passing into nearly linear-conic. Panicle 8-12 in. ; lower branches distant; lowest 
bract l} in. long; secondary branches flexuose, minutely scabrous-puberulous. 
Spikelets in clusters of 1-5, 1 in. long, 2-1-fld., brown; lowest flower perfect, nut- 
“wing. Fl. glume ovate-lanceolate, at least as long as the two lower empty glumes, 
ut 7a in., sessile, brown; beak } nut. 
Var. crassa; stems usually 6 ft. ; spikelets rather larger, densely clustered, 2-4 
flowers and 1-3 nuts; styles and filaments conspicuously exserted. Baumea crassa,

Thwaites, C.P. 845.—In the Ceylon examples (crassa type), with which the Bengal 
agree, the roots are thick black (the plant probably not stoloniferous), the nuts are 
nearly twice as long as in the Australian plant shining brown. But in the Khasi 
plant, stolons are generally present and the nuts are like those of C. riparium, Benth,
