NEW SPECIES OF CALIFORNIA PLANTS. 
ALICE EASTWOOD. 
Salix Covillei. 1-2 meters in height, older stems chestnut 
brown, younger ones clothed with a glaucous bloom which 
persists at least through the second ¢eason. Leaves on flowering 
branches without stipules, oblong to oblanceolate, 3-5 cm. long, 
5-10 mm. wide; petioles 2-3 mm. Jong; upper surface at first 
silky pubescent, later becoming almost glabrous; lower surface 
white, with short, silvery, silky hai:s, densely appressed ; apex 
and base acute; margins revolute at base, otherwise entire. 
Aments appearing before the leaves, sessile, scattered. Staminate 
aments ovate elliptical, short and broad, little more than 1 cm. 
. long, and about 8 mm. broad, white, with the long silky hairs 
- clothing the scales; these, broadly elliptical, acute at apex, dark 
brown, nearly 2 mm. long and about half as wide, clothed on 
both sides with fine white silky hairs, twice as long as the scale. 
Stamens two to each scale, filaments separate, about equaling the 
scales, inclined to be unequal; anthers with 4 cells; nectary % 
theslength of the scale. Pistillate aments oblong, slightly 
broader at base, 2—2.5 cm. long, almost 1 cm. broad; scales 
rounded at summit, broadening to the base, 2 mm. long, 1.5 mm. 
wide, almost concealed by the dense covering of white hairs. 
Capsules ovate, sessile, sericeous, with short, white, appressed 
pubescence. Style slender, 1 mm. long, branches divided to the 
junction with the style, rather slender. 
This was collected on Bubbs Creek, the south fork of Kings 
River, in Fresno County, California, July 10, 1899. It grew 
near the foot-bridge, along the edge of the creek. ‘The pistillate 
aments were discharging their seed. The description of the 
staminate was drawn from some aments which had apparently 
been frozen before being fully developed, and so had persisted. 
It seems to be identical with a specimen collected by Coville 
and Funston on the Death Valley Expedition (no. 1427). This 
was collected August 2, 1891, and is, of course, without flowers 
or fruit. It was identified with S. macrocarpa argentea Bebb* on 
~ * Contr. U. S. Natural Herb. IV. 199.
