NEW OR NOTEWORTHY SPECIES. 109 
AMELANCHIER SUBINTEGRA. Loosely but rigidly branched, 
5 to 8 feet high: leaves oval to suborbicular, commonly an 
inch long at maturity and nearly as broad, obtuse or trun- 
cate, serrate-toothed across the broad summit only, other- 
wise quite entire, of subcoriaceous texture, almost full-grown 
at flowering time, pale and obscurely tomentulose beneath, 
scarcely so above: racemes short, few-flowered, erect, the 
rachis, petioles and base of the broad-campanulate calyx 
villous-hairy; calyx-teeth short, deltoid and acuminate, not 
reflexed, villous within and marginally: petals oblong- 
cuneiform, obtuse, retuse, or emarginate, about 4 lines long: 
fruit not seen. 
Wooded hills of Lake and Napa counties, California ; col- 
lected by myself at the northern base of Mt. St. Helena, 
Aug. 1888, in mature foliage; Howell Mountain grade, by 
Mr. Jepson, May, 1893, in flower only; also by Mr. C. F. 
Baker, near Lakeport, 12 May, 1903, in flower only, and 
_ distributed by him under n. 2964. 
Rosa YAINACENSIS. Apparently low and depressed, the 
branches only 6 or 8 inches long, unarmed except by pairs 
of stout and prominent nearly straight infrastipular prickles: 
stipules terminating rather acutely, their margins closely 
beset with subsessile glands; rachis of the leaves with a few 
slender prickles and more numerous short-stelked glands: 
leaflets in about 3 pairs, rather closely approximate, oval to _ 
obovate, nearly sessile, doubly serrate, glabrous and deep- 
green above, pale and puberulent beneath; peduncles of 
the mostly solitary flowers densely glandular-hispid under 
the calyx, but the tube of this perfectly smooth and gla- 
brous, subglobose; the oblong foliaceous-tipped lobes with 
some scattered prickles about the basal portion: corollas 
small: fruit not seen.
