12. A. Rothrockii, (Iray. Shrubby, a foot or less higli, bushy, cinereous with 

 a minute appressed pubescence, but green or greenish, anil sometimes almost gla- 

 brous, ov slightly viscid : leaves from cuneato and 3-4-cleft above into oblong lobes 

 to cuneate linear or spatulato ami (especially on ilowering shoots) entire, or some of 

 tiio upj)er linear-oblDUg : heads crowiled, si)icate-panicled, greenish, 2^ to 3 lines 

 long, 10 - 12-liowered : scales of the campanulato involucre concave, rather iirm ; 

 the outer ovate and largely herbaceous ; the inner oblong : llowers all perfect and 

 fertile.

 rock in Wheeler's Exped., 1875. TLe Sutjc-brush of the region. Heads even thicker than those 

 of A. caaa. 



13. A. Palmeri, (^ray. Ajiiuuently wholly herbaceous and at least 3 feet high, 

 cinereous-puberulent : leaves narrowly linear and the lower 3 - 5-parted (the divi- 

 sions an inch or two long antl a line or more wide), with revolute margins, the 

 lower surface minutely white-woolly : heads greenish, very numerous in an ample 

 open panicle : scales of the involucre ovate, thin : Howers all perfect, most of theju 

 subtended by chalf similar to the inner scales of the involucre (or the inueimost 

 much smaller), — an anomaly in the genus, — Proc. Am. Acad. xi. 79.

9. S. Fremontii, Torr. & (Jray. A very well marked form of tliis species is 

 Var. OCCidentalis, (uay. Much more slender, a span to a foot high : leaves 

 from ovate-orbicular and repand to ubovate or spatulate and incised, thinner, most 

 of them on rather long and wing-margined petioles : heads smaller (4 lines high), 

 fewer-ilowered, and slender-peduncled.

 and Watson's and Parry's spucinieiis from the mountains of Utah and Wyoming.

A part of the generic character to Ije modified, and a portion of it tlirown into 

 a § 1, to contrast with the following : — 



§ 2. Scales of the involucre distinct to the base, the margins below at length more or 

 less involute : central /lowers (alwags ?) sterile, both anthers and ovary imjnr- 

 fect : stem leafy. 



3. R. Muil'ii, <'ray. A span or two high, slender, hirsute, and with some stalked 

 glands al)0ve ; leaves (about an incli long) linear, with somewhat revolute margins, 

 acute : heads terminal and short-peduncled, and also 2 or 3 lateral ones : involucre 

 carapanulate : bristles of the pappus 10 to 12, stouter, fully ecpialling the corolla in 

 length. 



In the Sien-a Nevada (the station unknown), ./. Muir. Head little over half an inch long. 

 Stem slender, very leafy below, sparsely so above. In habit unlike the genuine speeies of llallhir- 

 delta, but the floral characters accord. The mature akeues are tei'ete, but so they may be when 

 ripe in the original speeies.
