from Wasington Territory to Idaho and N. California (Sierra County, 
J. G. Lemmon). There still remains some uncertainty respecting the 
other tuberous-rooted species which yield the “ Biscuit-root” of the 
Indian tribes of Oregon. There seem to be two, both nearly acaules- 
cent, with large somewhat fusiform tubers, linear leaflets, and white 
flowers, — one described by Spalding as “the famous Biscuit-root or 
‘ Kamshit’ (when dried, ‘ Kanash’), dug in large quantities in May,” 
and the other somewhat taller, distinguished by him as “a large kind 
of Kamshit, the root not as good” as the other. Ripe fruit is unknown ; 
the immature ovary indicates an oblong fruit with strong dorsal ribs. 
Asarum Lemmont. Slender, somewhat pubescent, with elongated 
rootstocks: leaves cordate, rounded at the summit, thin and not mottled, 
glabrous above or nearly so: flowers rather small and mostly glabrous, 
with the short calyx-lobes (4 to 6 lines long) obtuse or only acute : 
connective but slightly produced beyond the anther: seeds narrowly 
ovate. —In the Sierra Nevada; Plumas and Sierra Counties, Mrs. 
R. M. Austin and J. G. Lemmon. Resembling A. caudatum of the 
Coast Ranges; distinguished especially by the more rounded leaves 
and short calyx-lobes. 
ABRONIA NANA. Perennial, dwarf and cespitose, with a thick 
branching caudex: stems very short and leafy: leaves ovate (a half- 
inch long or less), rough-puberulent, with slender glandular-pubescent 
petioles an inch long: peduncles 2 or 3 inches long, glandular- 
pubescent: involucre of 4 or 5 ovate-oblong scarious bracts, reddish 
at base, 4 or 5 lines long: flowers greenish, 6 or 7 lines long, the 
reddish limb 4 lines. broad: ovary turbinate, with 5 hollow wings: 
fruit unknown. — Near Beayer City, S. Utah, in dry ravines among 
junipers; Dr. E. Palmer (n. 404}, 1877). 
Potyconum (Duravia) BipweLiiz. Low (2 to 4 inches 
high): leaves and bracts cuspidate, brownish: spikes short, dense: 
stipules conspicuous, white, scarious and chaff-like, often exceeding 
the bracts (2 lines long), 2-lobed, the lobes entire or slightly lacerate 
at the summit: flowers pale rose-color, nearly a line long: akene 
narrowly ovate, included; the styles widely divergent.— Near Chico, 
California; Mrs. John Bidwell, May, 1878. With the following 
species allied to P. Californicum and confirming the section Duravia, 
which is to be distinguished from Avicularia chiefly by the linear 
3-nerved leaves and bracts, not jointed at the base, the solitary sessile 
spicate flowers, and the persistent styles. The original characters of 
the section as respects the fruit were drawn from immature specimens 
and are erroneous, the akene not differing essentially from that of
