 narrow, entire or sparingly cleft or parted : heads solitary, long-peduneled : involucre cam- 

 panulate, 4 or 5 lines high, of about 8 oblong bracts : pappus in the typical plant of narrow-

Var. integrifolium, Gray, 1. c. Low, often dwarf, cespitose-tufted, 3 to 10 inches

 summit, or at base and on sterile shoots cuneate and incisely lobed : heads rather long-pedun- 

 cled : involucre, &c, of the preceding, sometimes smaller and of only 6 bracts : palete of the 

 pappus mostly of same length, about equalling the very glandular but not hirsute corolla-

E. ambiguum, Gray, 1. c. Somewhat loosely floccose-woolly, or denudate : stems branch-

 lanceolate bracts, which are either distinct to the base or lightly coherent for two thirds their

 or the inner ones glabrous. — Lasthenia (Monolopia) ambigua, Gray, Proc. Am. Acad. vi.
