 scales, 6 to 8 inches long, recurved, the cauline shorter and soon re- 

 duced to sheathing oblong acuminate or acute lepidote bracts 12 to 6 

 lines long : flowering stem nearly 2 feet high, very sparingly branched ; 

 spikes 4 or 5 inches long, 6-8-flowered, glabrous, slightly flexuous ; 

 calyx little exceeding the acutish narrow appressed bract and about 

 equalling the internodes, 7 to 9 lines long ; petals long-exserted. — At

 long : inflorescence scurfy-canescent, cylindrical, 8 to 10 inches long 

 and over 2 inches broad, of numerous (20 to 30) distichous sessile 

 ovate-lanceolate 8-10-flowered spikes which are 2 or 2^ inches long 

 and an inch broad ; bracts tinged with red on the margins, those on the 

 rhachis more or less attenuate and the lower often much exceeding the

 or less scurfy, an inch long; petals greenish, 1| inches long, convolute 

 below into a tube as long as the calyx ; stamens and style exceeding
