SALIX LÆVIGATA, n. sp. Very glabrous, except the scales and = 
rachis of the catkin, and a few small caducous silky leaves at : 
the base of the shoots ; leaves elliptic-ovate or broadly lanceolate, 
pointed, finely serrulate, but the margin revolute and thus 
appearing entire, coriaceous, dark bluish green, glossy and prom- 
inently nerved above, paler beneath ; stipules small, ovate, cadu- 
cous ; petioles short (1’—4” long) not glandular; catkins cylindri- fe 
cal, 2 or 3 inches long in flower, the fertile becoming loose infruit, 
always borne on short lateral leafy branches; scales erose-den- 
tate at the apex, distinctly nerved, hairy at the base and on the 
inner surface; g¢ obovate, rounded and more evenly dentate, Ẹ 
narrower, truncate with a few irregular teeth, caducous (in out- 
line, when magnified, like the leaves of Potentilla tridentata); 
ovary.globose-conical, smooth, long stalked (as in S. amygaarot 
des) ; stigmas sessile, 2-lobed ; stamens 3—5.—California, at Santa 
Cruz, Dr. C. L. Andersson, to whom I am indebted for a very M-

A remarkable species of the Amygdaline group, distinguish- 
able from all forms of S. nigra Marsh. (the only near ally m the 
U. S.) by the conspicuous dentate scale, and very different foliage. 
S. lasiandra Benth., a western modification of S. lucida, has = 
obscurely dentate scale, but is otherwise very unlike. As tae 
buds expand, two or three small scale-like leaves appear clo het 
beneath and fringed on the margin with ferruginous silky hairs; 
these soon fall off; the lowest persistent leaves on the branches 
: are followed by, others broader, more pointed, on short age 
passing into the lanceolate taper-pointed form of the fully dev = 
oped foliage. /
