inches long ; filaments rather stout, scarcely attached to the base of the 

 style, the anthers nearly a line long, and the setaceous appendage of 

 the connective 1-2 lines long; styles short, nearly distinct, scarcely 

 equalling the anthers ; ovary inferior ; seeds ovate, smooth, 2 lines 

 long. — In the mountains of middle California, at an altitude of 

 4-7,000 feet. A. caudatum, which ranges much farther northward, is 

 not tufted and has smaller flowers upon slender pedicels, the calyx- 

 lobes narrower and more attenuate, filaments slender, anthers shorter 

 but much exceeding the acute apex of the connective, the styles united 

 and equalling the stamens, and the seeds somewhat smaller. 



Amaranths leucocarpus. Stout, 4-5 feet high, glabrous, green, 

 with spreading branches ; leaves lai-ge, ovate-oblong, subacuminate, 

 3-6 inches long, cuneate at base and decurrent upon the petiole, 

 which is as long or longer ; flowers in thick compact nodding spikes, 

 2-6 inches long, the lateral spikes divaricate ; seed large, over ^ line 

 broad, smooth, dull white or light brown, the central albumen promi- 

 nent. — Cultivated from seeds obtained by Col. Powell in Arizona, and 

 well marked by its dense nodding spikes, its large leaves and by the 

 characters of its seeds, which are collected by the Indians for food. 



Amarantus Powellii. Slender, 4-5 feet high, glabrous, the 

 stem becoming bright red, branches erect ; leaves small, oblong- 

 lanceolate, 2 inches long, cuneate at base, the slender petiole shorter ; 

 flowers in close narrow compound spikes, the lateral ones erect ; seed 

 nearly black, shining, less than half a line broad, lenticular, very 

 minutely and slightly tuberculate. — Likewise cultivated from seeds 

 brought from Arizona by Col. Powell, and apparently a very distinct 

 species. A. albus and retrojiexus were also raised from the same 

 collection of Arizona seeds, used as food by the Indians. The only 

 other species known from our western territory and apparently in- 

 digenous are A. chlorostachys and BUtum. 



Eriogonum (Alata) triste. Sparingly villous or glabrate ; scape 

 tall and erect, the inflorescence an elongated alternately branched 

 panicle, with the branches dichotomous ; bracts small, herbaceous, 

 linear ; involucres glabrous, acutely 5-toothed, on rather slender smooth 

 peduncles ; flowers a line long, glabrous, brownish red, the lobes ob- 

 long, obtuse ; achenium narrow, 2 lines long or more, membranously 

 winged its whole length. — Kane County, Southern Utah, collected by 

 Mr. A. L. Siler. Radical leaves probably narrowly oblanceolate as 

 in the other species of the group. With the habit of E. alatum, but 

 nearly glabrous above and the flowers dark red. 



Eriogonum (Umbellata) ursinuji. Densely tomentose, the
