196 PITTONIA. 
Sandy deserts of the lower Humboldt River, Nevada, near 
the Humboldt House, collected by the writer, in leaf and 
fruit ouly, 22 July 1894. Intimately allied to A. Serenoi, 
Sheld. (A. nudus, Wats.), but differing in its short calyx- 
teeth, small subsessile pubescent pods, as also by the much 
greater size of the whole plant, and its desert lowland habi- 
tat, A. Serenoi belonging to the more fertile elevations of the 
mountains, but being nevertheless a small and inconspie- 
uous bush as compared with this large tufted and reedy or 
broomy denizen of the dry desert plains. 
ASTRAGALUS CYMATODES. Related to A. caryocarpus, and 
perennial, with stems more slender, less leafy, decumbent or 
assurgent, less than a foot long in full maturity ; herbage 
sparsely villous-pubescent under a lens: leaflets in 10 to 12 
pairs, oblong, retuse or emarginate, about 2? inch long: 
flowers unknown: calyx subcylindric, the narrowly lanceo- 
late subequal herbaceous teeth more than half as long as 
the tube: pods hard-eartilaginous, of quadrate-ovoid out- 
line, somewhat compressed, almost completely 2-celled, about 
1 inch long including the stout straight subulate beak of a 
line’s length, the sutures prominent, the sides closely and 
prominently «wavy-striate transversely, the body of the 
raised on a stoutish stipe twice as long as the calyx.

The specimens from which the above diagnosis is drawn © 
have long been in my herbarium, from somewhere in the 
upper part of the valley of the Sacramento in California. 
They are in mature fruit only, and indicate a fleshy-podded 
species manifestly allied to A. caryocarpus, and also recalling 
my A. circumdatus of Lower California. The long-peduncled 
spikes are short and few-flowered, judging from their ap- 
pearance in the fruiting state. 
AsTRAGALUS Wirsowir. Perennial, the several stoutish 
stems less than a foot high, erect from a short decumbent 
base, with short nodes and long leaves; herbage almost gla- 
brous, the stems purplish: leaves subsessile ; stipules thin, -
