AND GENERA OF PLANTS. 311 



Hab. On the sea-coast of the Oregon and Upper California. A large, rather succulent leaved 

 plant, sending up several stems about a foot high, with leaves and flowers very similar with those 

 of Erigeron bellidifolius. Stem and uppermost leaves softly hairy, somewhat three-nerved. 

 Flower very large, rays pale red. Achenium angular, Avith four or five brown stri8e. Pappus 

 double, rays of the pappus twenty to twenty-four, about the length of the discal florets, and not 

 deciduous. 



Ajinual or perennial. Leaves entire or lohed. Pappus double in ray and dish, 

 the inner of eight to fifteen, short, deciduous, somervhat scabrous rays. Oly- 

 gotrichium; (Stenactis in part.) 



Erigeron *divaricatum; Q hirsute, stem branching from the base ; branchlets 

 one-flowered, rather naked, fastigiate ; radical leaves spathulate, the rest linear, 

 sessile, acute, attenuated below, all entire ; inner pappus of about eight setse ; 

 rays very numerous, narrow, white. 



Hab. In the Rocky Mountains and the plains of Oregon. About one foot high, at length very 

 much branched, the leaves an inch or more long, about a line wide. Pappus double in ray and 

 disk, the inner of remarkably few rays, very deciduous. 



Erigeron tenue, (Gray.) E. quercifolium, Nutt. and Decand., not of Lam., 

 pappus double in ray and disk, the inner of about twelve short deciduous 

 bristles. 



Erigeron strigosum (3. gracile; stem leaves and involucrum pubescent, 

 branches fastigiate. 



Hab. Oregon plains. 



Erigeron ^occidentale, % ] hispid with a short pubescence, corymb compound, 

 irregular; lower leaves oblong-lanceolate, obtuse, subserrulate, upper linear en- 

 tire; sepals lanceolate, acute, scarcely hirsute; rays very numerous, red; inner 

 pappus of about twelve rays; the outer very distinct. 



Hab. In Oregon. A low perennial species, with broadish leaves on the lower part of the stem. 

 Allied to E. strigoswn, but scarcely the same, with red flowers and broad leaves. 



§. TRiMORPHiEA. (Decand. Vol. V., p. 290.) 



Erigeron *nivale; stem subcaespitose and hairy at the base, mostly with one 

 capitulum; radical leaves spathulate, cauline lanceolate, acuminate, subamplex- 

 icaule; summit of the stem and involucrum gland ularly pubescent; sepals linear
