11. X. scabridula Rendle sp. nov. 
Habit of X. huillensis but less rush-like. leaves markedly rugulose 
with scabridulous margin and markedly striate scapes; spikes 
few-flowered (4-or more) slightly larger than in YX. huillensis, bracts

Leaves } to 24 in. by } to d line; scapes 2 to 64 in.; spikes
