294 BOTANY. 



nate, very short and scale-like, broad and amplexicaul at base, acute, often 

 nearly obsolete ; spikes numerous, alternate, sessile or sometimes peduncled, 

 cylindrical, 3-10" long, 1" or more in diameter ; scales rhomboidal, obtuse, 

 free at the top and sides; flowers in threes, a little exserted ; seed very 

 small, less than j" in diameter. — About Great Salt Lake and in alkaline val- 

 leys westvs^ard to the sinks of the Carson and Humboldt Rivers, where it 

 grows luxuriantly in large tracts that would be otherwise destitute of vege- 

 tation. If has been referred to Salicornia fruticosa, L., (^Arthrocnemum, 

 Moquin, in part,) but is widely different. Nor does it accord with any of 

 the described species of Halostachys, though approaching H. Ritteriana, 

 Moq., of Spain and Chili. Flowering in August; fruit still immature in 

 October. (995.) 



Su^DA MAEiTiMA, Dumort. Along the seacoast from Flprida to New 

 England, and on alkaline plains from the Platte to Western Texas and west- 

 ward ; California, (Douglas.) Frequent in the alkaline valleys of Nevada 

 and Utah, growing 1-2° high, erect and diffusely branched, glabrous or 

 sometimes purberulent, deep-green or the whole plant purple ; cauline leaves 

 about 1' long and less than 1" in diameter; seed i" broad, shining, very 

 minutely punctate-striate near the margins ; flowering in July, fruiting in 

 September. (996.) 



Su^DA DEPEESSA, Ledeb. (Salsola, Pursh, Fl. Am. 197. Chenopodina, 

 Moq., DC. Prodr. 13. 2. 164.) Annual, herbaceous, prostrate, very much 

 branched, glabrous, often reddish ; stems (3-6" long) and branches usually 

 more or less flexuous ; leaves mostly flatter and broader than in the last ; 

 flowers and seed similar. — Apparently distinct from S. maritima, but perhaps 

 identical with S. prostrata, Pall., which is the older name. Moquin's de- 

 scription differs essentially from that of Pursh, though both were drawn 

 from Nuttall's specimens. Reported from the Saskatchewan, Dakota, and 

 Colorado. Alkaline flat near the head of Humboldt Valley, Nevada. (997.) 



Su^DA FEUTicosA, Forsk. DC. Prodr. 13. 2. 156. Var. (?) Stout 

 and shrubby at base, 2-3° high ; stems suberect, branched, leafy, glabrous ; 

 cauline leaves 1-2' long, ^-l" in thickness, narrowed at base, scattered or 

 rather crowded, those on the branchlets shorter, acute or obtuse ; flowers 

 1-8 in the axils, fertile or staminate ; calyx-lobes nearly 1" long, obtuse and 

 somewhat hooded, narrowly scarious on the margins; stamens exserted; 

 seed black and shining.-This is 522 Fremont from the Sweetwater in Cen-
