180 A SKETCH OF THE BOTANY OF THE BASIN OF THE GREAT SALT LAKE OF UTAH. 
Lateral flowers abortive, neutral, on short pedicels, short-awned; the perfect flower, bear- 
ing an extremly long awn (2 inches long,) about the length of the similar capillary glumes 
—all spreading. Antelope Island. June. Major Stansbury. 
Etymus striatus. Willd. Gray’s Man. p. 571. (Wild-Rye.) Spike dense but slender, 
upright or slightly nodding, 3—4 inches long, spikelets mostly in pairs, minutely bristly- 
hairy; glume linear awl-shaped or truly awl-shaped; bristle-awn about three times the 
length of the flower, not counting their capillary awn which is 1 inch long. Leaves rather 
narrow and sheaths smooth, or hairy, or downy. Antelope Island. June. Major Stans- 
bury. 
Buncu-Grass, mentioned by Maj. Stansbury, &c.* 
EQUISETACES. 
Equisetum Ayemale. Linn. Gray’s Man. p. 587. (Scouring Rush.) Some Horsetails, 
probably the above, are mentioned by Major Stansbury and Col. Fremont as common in 
- the meadows at the foot of the mountains and, generally, in marshy grounds. 
* Mr. George Thurber, an able botanist who has visited the Western regions, informs me that prairie men 
call all very good grass on high land Grama, and any rather coarse grass, growing in tufts, Bunch Grass, 
without regard to genera or species. The Bunch Grass of Oregon is Hlymus condensatus, Presl. He has 
had also Bouteloua curtipendula from the far West under this name. Of the grasses mentioned in Stans- 
bury’s report by Prof. Torrey, Triticum repens and ELlymus Striatus are the only ones sufficiently branchy 
in habit to merit the name of Bunch-Grass.
