AND GENERA OF PLANTS. 435 



Hab. With the above, which it wholly resembles, except the leaves, and red flowers; four to 

 six inches high. Leaves three or four inches long, half to three-quarters of an inch wide, with 

 narrow, curving, and mostly runcinate teeth or segments. Achenium distinctly rostrate, rather 

 flat, with shallow, acute ribs, nearly as long as the coarse, white and bristly, scarcely scabrous 

 pappus. 



*MALACOMERIS. 



Capitulum many-flowered. Involucrum widely campanulate, loosely imbri- 

 cate in about two nearly equal series, irregularly bracteolate or caliculate at 

 the base; the segments smooth, linear, nerveless, and membranaceous on the 

 margin. Receptacle naked. Anthers bisetose at base. Achenium oblong, 

 erostrate, truncate, somewhat pentagonal, with about fifteen very slender 

 striae. Pappus white, in several series, slenderly pilose, deciduous, long, 

 and somewhat barbellated towards the base. — A suffruticose, softly tomen- 

 tose, and canescent plant of Upper California. Leaves pinnatifid with few 

 linear segments; stem short, above scapoid, one to three-flowered; flowers ra- 

 ther large and yellow. (The name is given in allusion to the soft pubescence. ) 



Malacomeris * incanus. 



Hab. St. Diego, on an island in the bay. Suffruticose and decumbent, base of the branches 

 woody. Radical leaves in tufts, whitely and softly tomentose ; primary leaves smoother, all more 

 or less pinnatifid and linear, with very few segments, the summit trifid; scape or stem risino- two 

 or three inches above the leaves, one to three-flowered, towards the summit becoming smoother, 

 with numerous, smooth, ovate bractes, six or eight of which form a sort of caliculum. Involucrum 

 smooth, the segments numerous, linear and partly acute, all of them of equal height. Florets very 

 numerous and exserted, pubescent on the tube. Stigmas nearly smooth, slender, and but little 

 exserted. Pappus three or four times longer than the short, smooth achenium. The fruit some- 

 what like that of Hieracium, but not ribbed, and the involucrum and habit of the plant that of 

 Troximon. 



BARKHAUSIA. (Moench.) 



Barhhausia elegans. Crepis elegans, Hooker, Flor. Bor. Am., Vol. L, p. 

 297. Scarcely distinct from B. nana, which appears like a dwarf growth of 

 this species. 



*CREPIDIUM. 



Capitulum many-flowered. Involucrum double, the inner of a single series of 

 leaflets, (about twelve,) the outer short and caliculiform. Receptacle naked. 

 Achenia linear-oblong, subpentangular, erostrate, truncate at the summit,
