 Synopsis, p. 299. — Hooker, British Flora, vol, i. p. 33. 



Root fibrous. Stem erect, from six to ten inches high, solitary, 

 smooth, finely striated, leafy, the lower part frequently bent and swollen 

 into a solid tuber or bulb ; sometimes there are several, one above ano- 

 ther, between the joints, which are in this part of the stem near each 

 other, and from each of them roots and a single stem are put out. 

 Leaves narrow, striated, shorter above, with long swelling sheaths. 

 Ligula lanceolate, decurrent, striated. Inflorescence subspicate, dense, 

 the pedicels for the most part short, each bearing a fertile and an abor- 

 tive flower. Glumes lanceolate, acute, and purple at the point, quite 

 free to the base, slightly downy all over, but more so on the keel and 

 ribs, which are purple. Glumella blunt, shorter than the glumes, with 

 an a^vn arising from near the base, and about twice as long. Anthers 

 scarcely longer than the glumes. Styles united. Stigmas feathery, 

 protruding. Sead ovate.

Root fibrous. Stem varying in length from six inches to two feet, 

 prostrate in the lower part, and frequently sending out roots and 

 branches from the joints, smooth, striated^ leafy, erect from the last 

 joint. Leaves short, finely ribbed, rough on the upper side and edges,

 (jula oblong, clasping the stem. Inflorescence a dense blunt erect spike, 

 from one to two inches long, often purplish. Glumes obtuse, united at
