v Coleosanthus albicaulis sp. nov. 
Brickellia Wrightit and B. californica A. Gray, Syn. Fl. 1°: 
106; both in part. 1884. 
Shrubby at the base, 0.5-1 m. high; bark of the older wood 
brownish, striate and fissured, that of the younger branches straw- 
colored or grayish, hirsute-puberulent, more or less flaky ; leaves 
short-petioled ; blades broadly cordate, 2-5 cm. long, strongly 
veined, thick, scabrous-puberulent, crenate-dentate ; inflorescence 
consisting of small axillary clusters scarcely exceeding the leaves, 
of 2-6 heads on short peduncles ; heads 10-20-flowered ; involucres 
turbinate ; lower bracts short-ovate, the inner linear, all acutish or 
obtuse, greenish straw-color; corolla cream-color ; pappus white. 
This has been confused mostly with C. Wright, but the type 
of that species has more ovate leaf-blades, longer petioles, longer 
flower clusters, which exceed the leaves, and purple-tinged involu- 
cre, the bracts of which are very obtuse or rather rounded at the 
apex. It is rather nearer’Coleosanthus reniformis (Arickedlia 
rentformis A. Gray); from which it differs mainly in the longer, 
cordate, not reniform leaf-blades and larger and sharper teeth. It» 
grows on the foothills and in cafions at an altitude of 1500-2500 m.

| vGrindelia serrulata sp. nov. 
Biennial or perhaps short-lived perennial; stem glabrous, 
about 6 dm. high ; leaves sessile, oblanceolate or oblong, acutish, 
very viscid, 3-5 cm. long, finely and densely serrate ; inflorescence 
corymbiform ; involucre very viscid, about 15 mm. broad ; bracts 
subulate, very squarrose and reflexed; ligules 7-8 mm. long, I- 
1.5 mm, wide; pappus-awns apparently smooth; barbules seen 
only under a compound microscope. 
This is nearly related to G. perennis and G. squarrosa, From 
the former it differs in the closely and sharply toothed leaves, and 
from the latter in the oblanceolate instead of ovate or oval leaves. 
grows on plains at an altitude of about 1500 m. -
