* * Leaves very narrowly linear, commonly acerose and often rigid and pun- 
gent; western species. ‘ 
+ Sepals broadly ovate, obtusish, sometimes apiculate: flowers not densely 
aggregated. 
A. capillaris, Poir. Leaves chiefly grouped at the base in fasci- 
cles upon a multicipital caudex, }—24 inches long, somewhat pungent, 
little spreading ; the cauline few pairs, much reduced : stems 4-8 inches 
in height: petals obovate, considerably exceeding the short obtuse 
sepals. — Poir. in Lam. Encycl. vi. 380; Regel, Ost-Sib. i. 366. AC 
sine nardifolia, Anderson, Cat. 118. The typical glabrous form with 
straight leaves is comparatively rare in America but occasionally occurs 
with var. NARDIFOLIA, Regel, |. ¢. i. 372, which is glabrous with curved 
leaves (A. nardifolia, Ledeb. Fl. Alt. ii. 166, & Icon. FI. Ross. 65 
Hook. Fl. Bor.-Am. i. 98, t. 32), and the more common form vat. 
FORMOSA, Regel, |. c. i. 371, which has the stem and inflorescence 
glandular. (A. formosa, Fischer in DC. Prodr. i. 402 ; Hook. f. Are. 
Pl. 287, 322; Torr. Bot. Wilkes Exp. 243.) — Central California to 
Utah, Montana, and British Columbia. (Asia.) 
. ursina. Root stout, ligneous: caudex very densely multicip!- 
tal and bearing very close fascicles or rosettes of very short filiform- 
linear thickish glaucous glandular-ciliolate white-punctate apiculate 
leaves (but 2-3 lines in. length): stems few, erect, branched, slender, 
finely glandular-pubescent, 14-3 inches high, bearing one or two palls 
of short distant spreading and rather rigid leaves: sepals nerveless + 
petals white, oblong, slightly emarginate: alternate filaments glandu- 
liferous at the base: mature capsule considerably exceeding the caly%; 
about 6-seeded. — Dry hills, Bear Valley, San Bernardino Mts., S. B. 
& W. F. Parish, August, 1882. This species has much the habit of 
A. compacta, Coville, but much more obtuse sepals; it is most nearly 
related to A. capillaris, Poir., but differs in its condensed habit and in 
a waxy punctation of the leaves. 
aculeata, Wars. Leaves grouped chiefly in fascicles at the 
summits of a multicipital caudex, decidedly glaucous, rigid and pune 
gent and with age strongly spreading, 6-12 lines in length; — 
leaves few, shorter: stems simple up to the few-flowered cymes, 4- 
inches high: petals rather narrow, elliptic-oblanceolate, obtuse, I}- 
times as long as the sepals. — Bot. King Exp. 40, & Bibl. Index, 94. 
Chiefly in mountainous districts from Oregon (Nevius, Cusick, How 
ell) to N. Nevada (Watson), S. Utah, and Arizona (?). The seP® 
are variable and become more acute in the southern form, which Dd 
more difficult to distinguish from those varieties of A. congesta WHY" 
have an open inflorescence. :
