1. L. simplex, 4. Rich. Fl. Nowv. Zel. 142 (not of R. Br.).— 
Rhizome stout, creeping, clothed with chestnut-brown scales. 
Stems numerous, densely crowded, simple, slender, terete, rush- 
like, 1-5ft. high. Sheaths closely appressed, blackish-brown, 
distant, 14-4in. apart. Male inflorescence panicled; panicles
