Plants bright green, clambering among bushes to the height of 5 m 
or more, the main canes slender but strong, the very slender branches

glabrous except the margin and throat, or rarely the young ones 
sparsely hispid; ligule inconspicuous; blades linear-lanceolate, 5 to 
10 cm long, 2 to 6 mm wide, eradually narrowed to an acuminate 
apex, thin and lax, glabrous, the margins scabrous; panicles narrow, 
mostly less than 5 cm long, often partially included in the uppermost 
sheath, the branches short and appressed, the longer usually not more 
than 1 cm long, and bearing not more than 4 spikelets; spikelets 
similar to those of L. divaricata but less turgid. 
This species is easily recognized by its long narrow blades and 
pendent branches.
