AND GENERA OF PLANTS. 435 
Has. 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 
natrow, 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 
strie. 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. - 
Has. 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 rising 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. Involuerum 
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. (Meench.) 
Barkhausia elegans. Crepis elegans, Hooxer, 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,
