Flowers monoecious or dioecious, without bracts, dimorphous. Staminate flowers

 by a narrow erect slightly 2-lobed border, which becomes at length a broad circular 

 horizontal membranous veined wing. Ovary thin and hyaline, nearly filled by the 

 ovule. Style lateral, slender, adherent to the perianth, and terminated by two 

 thick exserted unequal stigmas. Seed vertical, with a double transparent mem- 

 branous testa. Embryo spiral, green, without albumen : radicle inferior. — A rigidly 

 and divaricately branched somewhat spinescent shrub, of saline localities ; leaves

 sistent scales spirally arranged, rhombic-ovate, acute : stamens about 3, soon decidu-

Frequent in the alkaline valleys of the Great Basin, from the Sierra Nevada eastward to the 

 Upper Missouri and the headwaters of the Platte and Canadian, and southward _to the Gilu ; 

 the most prevalent of the several shrubs bearing the name of " Grease- wood." Tlie wood 

 is very compact and hard, of a light yellow color, but the stems rarely exceed 2 or 3 mehes m 

 diameter, and are usually knotted and twisted ; the bush, however, though small is valuable tor 

 fuel, and often the only resource.
