AND GENERA OF PLANTS. 3ll 
Has. 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, with four or five brown stria. Pappus 
double, rays of the pappus twenty to twenty-four, about the length of the discal florets, and not 
deciduous. 
Annual or perennial. Leaves entire or lobed. Pappus double in ray and disk, 
the inner of eight to fifteen, short, deciduous, somewhat scabrous rays. OLY- 
GOTRICHIUM; (STENACTIs in part.) 
Erigeron *divaricatum; © 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 sete; 
rays very numerous, narrow, white. 
Has. 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.) . quercifolium, Nurr. and Decanp., not of Lam., 
pappus double in ray and disk, the inner.of about twelve short deciduous 
bristles. 
Erigeron strigosum (@. gracile; stem leaves and involucrum pubescent, 
branches fastigiate. 
Has. Oregon plains. 
Erigeron *occidentale, 2 ; 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. 
Has. In Oregon. A low perennial species, with broadish leaves on the lower part of the stem. 
Allied to E. strigosum, but scarcely the same, with red flowers and broad leaves.
