This accords very well with the male plant collected in Mr. 



Wrighfs first journey (No. 307) ; but the 



fertile heads are larger and fuller than 



the sterile, half an inch in length, many-flowered, and with a copious pappus of a 

 fulvous hue, manifestly inclining to reddish. The scales of the involucre are 3-4- 

 serial, very smooth, with a green centre, and more conspicuous hyaline margins 



than in the sterile plant,

The 



fertile plant of the preceding enables me to identify this as a variety of B. Wrightii, 

 of which hefore the sterile plant alone was known. The mature pappus is half an 

 inch long, of a reddish huc, in Gregg's specimens almost sanguineous.

(1405.) 



A very woolly, small herb, with the 



habit of a diminutive Micropus erectus, bcginning to blossom when only an inch 

 high; when the stem is terminated by several heads in a glomerate cluster, sur- 

 rounded by linear-lanceolate leaves of 3 or 4 lines in length, similar to the cauline 

 ones. It soon branches more or less from the base, and is often proliferous from 

 the glomerule. Hcads ovoid or subglobose, 2 or 3 lines in length, rather larger 

 than those of S. gnaphalioides, and much more woolly ; the paleae being thickly 

 covered with long and implexed wool, except the scarious tip. Thcse are like those 

 of the Californian species, except that they are narrowly oblong (instead of broadly 

 ovate), and with the lower part, inclosing the flower, contracted and wholly in- 

 folded, instead of having a mere saccate fold in the kcel. Keceptacle columnar 

 and elongatcd; the fructiferous paleee, looking like little pcllets 

 aw^ay at maturity. Sterile flowers 3 or 4 at the apex of the receptacle, naked, or 

 barely subtended by oblong and glabrous paleee ; the abortive ovaries furnished with 



pappus of three or four slender and smooth, slightly clavellate 

 bristles. Anthers caudate. 



A true congener of S. gnaphalioides. I see nothing to separate it, nor 

 the other Evacoid genera, from the GnaphalicEe.
