Open woods, &c., from HuiaboKlt uiul Neviula to San Diego Counties, both tlie broader and 

 the narrow-lea vt!d I'ornis. Var. inornatum, which may prove distinct, Mendocino Co., Kellogg 

 and Harford, in several forms; Upper Sacraii>cnto (Newberi-y, "A". JJoiujlasii, var."); near 

 Uonner Lake {Torrcij), and Sierra Valley, Lemmon, &c. If this species, through its longer- 

 leaved forms, should be found to pass into E. decumbens, Nutt., of Oregon, it will still be most 

 l)roper to preserve the name q{ E. foHosum, of the sanro age as the other, although Nuttall lirst 

 described it from an imperlect si>ecimen, and not very correctly as to the akene ; but he re-identi- 

 fied it in his pai)er on Dr. (iambel's collection. 



Kellogg and Harford's No. 31)8 is a remarkable dwarf form, apparently of the var. inonialum, 

 approachmg E. sujifilcx : the involucre is minutely glandular, as also is tho minute roughi.sh 

 punescencc on the branches and leaves. 



13. E. Bupplex, Gray. Villuns-liirsute ; stems a span or two long from slender 

 rootstocks, decumbent, mo.stly simple, terminated by a solitary and peduncled head : 

 leaves spatulate-lanceolatu, mostly acuto (about an inch long and 2 lines wide), the 

 uppermost becoming linear : involucre villous (about 4 lines high), the scales nearly 

 equal and loose: rays wholly wanting: pappus nearly simple. — Proc. Am. Acad, 

 vii. 353. 



Humboldt and Mendocino Counties, Bolundcr, Kellogg. Collected by Mr. Andrews several 

 years ago, station unknown. 



= = Pappus conspicuously double, the 07iter manifestly chaffy : rays very numerous 

 or none. {Hoot perhaps not perennial.) 



U. E. concinnum, Torr. & Gray. Very hirsute or hispid with long spreading 

 hairs : stems tufted, a span or more high, commonly branching, more or less leafy : 

 leaves spatulate-linear or the radical ones spatulate : involucre hirsute (about 2 lines 

 high), its scales nearly ec^ual : rays narrow, purple or white, 4 or 5 lines long, 

 or in tho 



Var. aphanactis, Gray ; the rays wanting or reduced to an abortive ligule 

 shorter than its style. — Proc. Ajn. Acad. vi. 540. 



Sierra Nevada on the eastern slope in Nevada (^nc?c?so?i, Torrcy), near to and doubtless within 

 the State line ; only the rayless form : thence eastward throughout the interior region. In both 

 forms the outer pappus is sometimes of narrow and acute, sometunes ol decidedly broad and 

 erose or truncate chaffy scales. If not perennial-rooted the species should be placed .ne.\t to 

 E. divergcns. 



.^+ ^+ ^^ Leaves broader {from lanceolate to obovale), in one sj)ecies serrate: rays 

 extremely numerous : outer pappus indistinct if any. 



15. E. speciosum, DC. Sparsely hirsute or almost glabrous : stem stout, erect, 

 1 to 2i feet high, furrowed, branching above, very leafy to the top, bearing 

 several or numerous corymbose heads: cauline leaves lanceolate, acute or acuminate, 

 entire, bright green, hirsutely ciliate {\\ to 4 inches long), closely sessile or i)artly 

 clasping ; the radical ones spatulate anif tapering into a petiole : heads rather large : 

 scales Zi the involucre .sparsely hirsute, very narrowly subulate : rays very narn.w 

 and mnnerous, violet-purple. — Stenactis speciosa, Limll. Bot. Peg. t. 1577 ; Hook. 

 Bot. Mag. t. 3G07. 



"California, Douglas" ; but it lias not since been oolleiled in the State ; yet probably it 

 occurs in the northern districts, as it is common throughout the moister parts ol Oregon and 

 Washington Territory, whence it was long ago introduced into gardens Heads showy, tully an 

 inch and a half in diameter, including the rays, which are halt an uich long. 



16. E. glaucum, Kor. Hirsute or villous with spreading hairs : stems ascen.l- 

 ing, a span to a foot high, leafy below, bearing solitary or few very large heails :
