164 MR. NUTTALL’S DESCRIPTIONS OF NEW 
K. *anaustiroriuM. Suffruticose, with infertile branches towards the base; leaves fasciculated and 
verticillated, linear-acute, narrowed below, whitely tomentose beneath, greenish but pubescent above, 
a verticel of about six leaves on the short stem; umbel simple, subtended by long, leafy bractes ; 
divisions of the many-flowered involucrum redctisl, pubescent; perianth reflected, smooth. 
A low, somewhat shrubby species, about a foot high; the stem tomentose; leaves 
an inch or more long, about a line wide; rays of the umbel seven or eight, short. 
Has. Western slope of the Rocky Mountains. (Nuttall.) 
K. *srrusum. Suffruticose; leaves linear, oblong, obtuse, beneath whitely tomentose, above pubescent, 
greenish ; stem tomentose, two or three times trichotomous, divaricate; bractes ternate, lanceolate- 
- acute; (flowers not seen.) 
Stem divided into many simple branches below; flowering stem bearing bractes 
only, divided compoundly and numerously, each division subtended by conspicuous, 
trifid bractes. 
Has. In the Rocky Mountains. (Nuttall.) 
Ki. micrantauM. Leaves nearly all radical, arising from a thickish, woody caudex, linear-spathulate, 
or narrowly oblong-lanceolate, narrowed below into longish peticles, whitely tomentose on both 
surfaces; scapes, bractes and involucres tomentose; umbel decompound, pedicels of the second 
divisions very short, with about three involucres in each; bractes acute or acuminate; involucres 
campanulate, very small, the teeth obtuse; flowers smooth, small and yellow, dioicous. 
In aspect nearly allied to EZ. campanulatum, but with rather longer and narrower 
leaves, and the involucres most of them sessile. 
era In the Rocky Mountains of Oregon. (Nuttall.) 
¥. *aupum. Nearly stemless, with a woody caudex; leaves very whitely tomentose, spathulate-obovate, 
obtuse, usually longer than the petiole ; bractes. minute, appressed; umbel nearly simple, of few rays; 
involucrum tomentose, angular, with shortish teeth ; flowers numerous, smooth. 
Very nearly allied to E. dichotomum, but a smaller growing plant, with broader, 
shorter, and whiter leaves; branches of the umbel two or three, short; each branch 
_ bearing about two or three involucres, the uppermost pair of involucres sessile, so as 
to form a larger head than what ever occurs in E. dichotomum, and with the 
involucres not singly disposed in a forked spike as init. Flowers larger and smooth, 
the filaments slightly hairy at the base, achenium with acute angles. 
Has. Rocky Mountains of Oregon. (Nuttall.) 
E. _*ROSMARINIFOLIUM, Shrubby and much branched, smooth or somewhat pubescent; leaves clustered, 
nearly linear, revolute on the margin, slightly tomentose beneath; umbel pedunculate, compound, 
_ bractes leafy, numerous; involueres usually smooth, with acute teeth: perianth mostly glabrous. 
Nearly allied to E. fasciculatum, but never with either oblong or elliptic leaves. 
A stoutish low bush with brown brittle branches. Leaves smooth, three-fourths of
