330 COMPOSITE. Erigeron. 



Var. Stenophyllum, Gray. Leaves a line or less in width, sometimes becoming 

 almost filiform. E. stenophyllum, Nutt. PI. Garnb. 1 76, not of Gray in Pacif. R. 

 Rep. iv. 98. 



Var. inornatum, Gray. Leaves varying from spatulate-linear and 2 or 3 lines 

 wide to very narrowly linear . involucre glabrous : rays none. 



Open woods, &c., from Humboldt and Nevada to San Diego Counties, both the broader and 

 the narrow-leaved forms. Var. inornatum, which may prove distinct, Mendocino Co., Kellogg 

 and Harford, in several forms; Upper Sacramento (Newborn/, " E. Douglasii, var.") : near 

 Douner Lake (Torrey), and Sierra Valley, Lcmmon, &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 

 proper to preserve the name of E. foliosum, of the same age as the other, although Nuttall first 

 described it from an imperfect specimen, and not very correctly as to the akene ; but he re-identi- 

 fied it in his paper on Dr. Gambel's collection. 



Kellogg and Harford's No. 398 is a remarkable dwarf form, apparently of the var. inornatum, 

 approaching E. supplex : the involucre is minutely glandular, as also is the minute roughish 

 pubescence on the branches and leaves. 



13. E. supplex, Gray. Villous-hirsute ; stems a span or two long from slender 

 rootstocks, decumbent, mostly simple, terminated by a solitary and ped uncled head : 

 leaves spatulate-lanceolate, mostly acute (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, Bolandcr, Kellogg. Collected by Mr. Andrews several 

 years ago, station unknown. 



= = Pappus conspicuously double, the outer manifestly cliaffy : rays very numerous 

 or none. (Root perhaps not perennial.) 



14. 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 equal : rays narrow, purple or white, 4 or 5 lines long, 

 or in the 



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

 shorter than its style. Proc. Am. Acad. vi. 540. 



Sierra Nevada cm the eastern slope in Nevada (Anderson, Torrey), 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, sometimes of decidedly broad and 

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

 E. divergens. 



++ ++ ++ Leaves broader (from lanceolate to obovate), in one species serrate : rays 

 extremely numerous : outer pappus indistinct if any. 



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

 1 to 2 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 (1| to 4 inches long), closely sessile or partly 

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

 scales of the involucre sparsely hirsute, very narrowly subulate : rays very narrow 

 and numerous, violet-purple. Stenactis speciosa, Lindl. Bot. Reg. t. 1577; Hook. 

 Bot. Mag. t. 3607. 



" California, Douglas " ; but it has not since been collected in the State ; yet probably it 

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

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

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



16. E. glaucum, Ker. Hirsute or villous with spreading hairs : steins ascend- 

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