Benth. & Hook. Gen. ii. 297 (excl. § 3, 4) ; Gray, Proc. Am. Acad. viii. 651, & 

 Bot. Calif, i. 335. — Our 'species, of the section Bombycil^na (with woolly 

 fructiferous bracts smooth and crestless), approach Stylocline and Filago in the 

 points which distinguish them from the European species. 



M. Californicus, Fiscii. & Meyer. Slender, erect, 6 to 12 inches liigh : leaves mostly 

 linear : fructiferous bracts 5 or 6, at length firm-coriaceous, somewliat hali'-obcordate or half- 

 obovate in outline, straight anteriorly, and with the soon erect beak-like tip largely scarious.

 cholepis) aiu/iistifolius, Nutt. Trans. Am. Phil. Soc. n. ser. vii. 3.39. — Plains and open ground 

 from S. California northward, toward the coast, to Oregon. Heads vary in the wool, from 

 long and copious, as in M. Immbijcinus, to short, as in the subjoined 



Var. subvestitus, Gray, Bot. Calif. 1. c. Small; the wool of the bracts all short 

 and wholly a])pressed. — Arroyo Grande near Monte Diablo, California, Brewer. 



M. amphibolus, Gray. Resembles the more loose-woolly forms of the preceding: female 

 tiowcrs about 10, somewhat imbricated on an oblong receptacle; their fructiferous bracts 

 membranaceous or merely chartaceous at maturity, the beak au ovate almost wholly hyaline 

 appendage which in flower is almost as long as the body and inflexed, at maturity porrect : 

 sterile flowers subtended by some linear thin chaff, and with a pappus of a few bristles. — 

 I'roc. Am. Acad. xvii. 214. — California, Walnut Creek near Martinez, Brewer, anJ coll. 

 (probably in same district) Kdloijg <j- Harford, distrib. 416. 



55. STYLCCLINE, Nutt. (Stl'Xo?, a column, and K\iv7], a bed, or 

 recei)tacle, from the form of this.) — Floccose-woolly annuals, a span or less in 

 height, branched from the base, erect or spreading, with entire alternate leaves 

 and more or less glomerate heads. — Nutt. Trans. Am. Phil. Soc. n. ser. vii. 

 338 ; Gray, Proc. Am. Acad. viii. 652, & Bot. Calif, i. 336. Micropus § 3 & 4, 

 Benth. & Hook. Gen. ii. 296. — Includes, besides the following species, S. (Diplo- 

 cymhium) Gnjjit/iii of Afghanistan, most related to our second and very distinct 

 section. 



§ 1. EuSTYLOCLiNE, Gray, I.e. Fertile flowers numerous; their chaffy 

 bracts pluriserially and closely imbricated in an ovoid head, thin, with at least 

 the broad tips hyaline (barely a green midrib or centre), ovate in outline, promptly 

 falling from the recejitacle after maturity along with the loosely enclosed akene ; 

 those subtending the sterile flowei'S all scarious-hyaline and deciduous. Pajipus 

 of a very few capillary bristles generally present with the sterile flowers. — Sty- 

 locline, Nutt. 1. c. 



S. gnaphalioid.es, Xutt. 1. c. Leaves l)roadly linear or the upper oblong, obtuse : fruc- 

 tiferous bracts broadly ovate, mo'derately woolly on the back, almost wholly hyaline-scarious, 

 a firmer central portion at base saccate-couduplicate and enclosing the narrowly obovate 

 oblique laterally compressed akene. — Gray in Pacif. R. Rep. iv. 101, t. 13, &c. — Open 

 grounds, California from the Stanislaus southward ; first coll. by NutlalL 



S. micropoides, Gray. Leaves somewhat narrower and rather acute : heads more woolly, 

 ai)pcariiig Ic^s scarious and imbricated; fructiferous bracts having a narrower oblong-ovate 

 hyaline tip, tlie oblong body densely long-woolly, without hyaline expanded margins, but 

 wholly enwrapping the nearly straight and slightly compressed akene. — PI. Wright, ii. 84, 

 & Bot. Calif. 1. c. Micropus (h-aijana, Ilemsl. Bot. Centr.-Amer., name only. — Arid plains, 

 S. California through S. Nevada and Arizona to New Mexico; first coll. by Wright. 



§ 2. ANCiSTROcXRPnus,Gray. Fertile flowers 5 to 9, loosely disposed on the 

 slender receptacle ; their enclosing bracts cymbiform, of firm texture except the 

 narrow hyaline tip, tardily if at all deciduous at maturity ; the few sterile flowers 

 involucrately subtended by about 5 larger open bracts ; these herbaceo-coriaceous,
