Shrub, up to over 2 m. high, much branched, many-noded ; 

 main culms and branches usually ascending in curves, glabrous, 

 terete, hard ; lower internodes more or less exserted from the 

 persistent or slowly decaying sheaths, whitish glaucous, up to 

 7 cm. long, upper enclosed, much shorter to very short. Leaves 

 crowded on the young branches, forming " feathery bunches," or 

 more or less distant, glabrous ; sheaths terete, tight, firm, smooth,

 attenuated from the slightly rounded base (2 mm. wide), into a 

 long setaceous point, 2-35 cm. long, more or less glaucous, firm, 

 smooth, with about 7 primary nerves alternating with very fine 

 secondary ones. Peduncles slender, 5-10 cm. long, more or less 

 exserted from the uppermost bladeless or nearly bladeless sheath, 

 with a tuft of hairs at the upper end. Racemes paired, one 

 sessile, the other on a slender peduncle (5-6 mm. long), sub- 

 parallel, silky, 2*5-3 cm. long, densely hairy all over the back and 

 edges ; hairs white, very fine, the longest as long as the joint ; 

 pedicels similar to the joints, 4 mm. long. Sessile spikeUts linear-
