340 COMPOSITE. Antennaria. 



Var. pulcherrima, Hook., is often a foot and a half high, with lowest leaves 3 

 to 5 inches long, and 3 to 12 lines wide; the uppermost reduced to linear or subu- 

 late bracts. 



Not yet detected within the limits of California, the nearest stations being in the Havallah and 

 East Humboldt Mountains, Nevada, Watson. The next much resembles it. 



5. A. luzuloides, Torr. & Gray. Silvery-silky : stems slender, 8 to 20 inches 

 high : radical and lower leaves from linear-lanceolate to spatulate, obscurely 3-nerved, 

 the others linear : heads small (2 or 3 lines long), numerous in a corymbose cluster: 

 involucre nearly glabrous; its scales barely brownish at base, all with white (or 

 rarely rose-colored) and rather papery tips, those of the sterile heads very obtuse, of 

 the fertile less so : akenes glandular. The typical form, with all the leaves very 

 narrow, is known only in Oregon and Washington Territory. 



Var. argentea, Gray, has all the lower leaves wider, oblanceolate or even spatu- 

 late, an inch or so long, 3 or 4 lines broad. Pacif. R. Rep. iv. 54. A. aryentea, 

 Benth. PL Hartw. 319. 



Mountains, Upper Sacramento to Mariposa Co., above the Yosemite Valley, &c. Bristles of 

 the pappus in the fertile plant very slightly united at base, much less so than in the American 

 forms of A. Carpathian. 



+- -t- Stems simple or branched from a cespitose base, leafy : the heads panicled or 



racemose and narrow. 



6. A. microcephala, Gray. Silvery-silky : stems slender, erect, a span high, 

 leafy nearly to the summit : leaves narrowly oblanceolate, or the lower spatulate 

 and the upper linear, above gradually reduced to small subulate bracts : heads small 

 (about 2 lines long) and rather few-flowered, numerous in a loose naked panicle : 

 involucre glabrate, of wholly scarious and thin obtuse scales, destitute of papery 

 tips : akenes very glandular : pappus of fertile flowers not longer than the corolla, 

 of the sterile with much dilated tips. Proc. Am. Acad. x. 74. 



Sierra Co., Lemmon: first detected in Washoe Valley, Nevada, by Mr. Stretch. Involucre 

 light brownish, the tips of the inner scales sometimes rose-colored. 



7. A. G-eyeri, Gray. Densely white-woolly : branches barely a span high from 

 a prostrate tufted base, very leafy to the top : leaves narrowly oblanceolate or spatu- 

 late, short : heads (3 or 4 lines long) thickish, cylindraceous, the fertile usually few 

 and somewhat spicate, the sterile hardly more numerous and rather corymbose : 

 involucre woolly below ; the inner scales with glabrous obtuse papery tips, which 

 are either ivory-white or deep rose-colored : bristles of the sterile pappus gradually 

 and moderately thickened upwards. PL Fendl. 107, & Pacif. E. Rep. 1. c. 



Northeastern borders of California, Newb'erry. Sierra Co., Lemmon. Discovered by Geyer in 

 the interior of Oregon. 



35. ANAPHALIS, DC. EVERLASTING. 



Heads discoid, incompletely dioecious ; viz. the pistillate with filiform 2-4- 

 toothed corollas very numerous, and a few (or occasionally no) hermaphrodite but 

 sterile flowers, with tubular 5-lobed corollas, in the centre ; the staminate nearly as 

 in Antennaria. Involucre campanulate, of many ranks of mostly snow-white scari- 

 ous scales. Receptacle flat, naked. Style in the staminate flowers usually 2-cleft 

 merely at the apex. Pappus a single series of capillary bristles, unconnected at base, 

 in the sterile flowers (at least in our species) slightly thickened upwards. Peren- 

 nials, all Asiatic (Himalayan, &c.), except one species, with wholly the aspect of 

 Gnaphalium, which is dispersed all round the northern hemisphere, especially 

 through North America, viz.
