with a few leaves, and terminating in a leafless peduncle 2-4 inches long; 

 lower leaves 3-nerved, spatulate, tapering into a petiole, upper leaves sessile 

 and spatulate, all (as also the stem and involucre) densely silky-pubescent; 

 involucral .scales thickish and lanceolate, in 2-3 series, and not longer than 

 the disk-flowers; rays about 15, cuneate, 3-lobed, nearly 6" long; hyaline 

 scales of the pappus broadly ovate, short-awned, glistening; achenia hairy, 

 cuneate. — This beautiful little species was obtained from Santa Fe, N. 

 Mex. (5), where it was first detected by Mr. Fendler in 1847. 



Actinella Richardsonii, Nutt. — South Park, Colorado (484) ; also 

 from Western New Mexico, Loew. 



Actinella grandiflora, T. & G. — Several erect branches, 6-12' high, 

 from the short stem ; entire plant more or less densely covered with a long, 

 loose wool; lower leaves pinnately or sometimes bipinnately parted, the 

 divisions linear; petioles margined with dilated and sheathing bases; invo- 

 lucre densely woolly; scales linear, acute, about as long as the hemispherical 

 disk; head (including the rays) \\-2.^ in diameter; rays oblong or cuneate, 

 6-12" long. Apex somewhat truncate, 3-toothed or lobed; disk-flower 

 lobes rather short and obtuse, glandular-hairy; achenia roughish-hairy, 

 with from 6-8 thin, lanceolate, acute pappus-scales. — In Colorado, the 

 most striking plant blooming at an altitude of 12,000 feet (578). 



Actinella scaposa, Nutt., var. linearis, Nutt. — Perennial, villous or 

 cinereous-pubescent ; scapes numerous, from a much-branched caudex ; 

 leaves many, narrowly linear, 2-4' long and hardly a line wide, glandular- 

 dotted petioles expanded into sheathing bases; scapes 4-12' long, terminat- 

 ing in a single head, which, with the rays, is 18" across; scales of the invo- 

 lucre in two series, oblong, obtuse and quite villous; rays oval or cuneate, 

 oblong, 3-toothed, the tube hairy; achenia pyriform, hairy, of five oblong or 

 oval scales, with or without short awns; disk-flowers with almost no tube, 

 and an upwardly dilated, gland-dotted limb, the lobes obtuse, short, and 

 glandular-hairy; achenia as in the ray, except that the pappus is conspicu 

 ously tipped with a bristle-like awn. — Covero, N. Mex. (104).
