West Atjstbalia. 



Stolons long, densely clothed by lanceolate striate dirty-straw-cclrd. scales. 

 Stems 3 ft., trigonous, under panicle flattened biconvex. Basal leaves often as long 

 as stem, hardly i in. broad j 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. j lower branches distant ; lowest 

 bract 1^ in. long ; secondary branches flexuose, minutely scabrous-paberulous. 

 Spihelets in clusters of 1-5, | in. loQg, 2-1-fld., brown ; lowest flower perfect, nut- 

 bearing. Fl. glume ovate-lanceolate, at least as long as the two lower empty glumes. 

 Ifut Jj in., sessile, brown j beak i nut. 



Var. crassa; stems usually 6 ft. ; spikeleta 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 0. Tipa/rmm, Benth.

 upper half terete or subtrigonous not transversely septate, panicle elongate
