Vi. 2 THE MUHLENBERG WILLOW. 250 
Var. 3.—Similar to these and resembling them in the naked, 
persistent, virgate stems which had borne the fructification mn 
the preceding spring, is a willow intermediate between these 
and S. rostrata, perhaps a variety of the latter, with broad, 
oblong, lanceolate leaves, waved or crenate at the margin, and 
revolute, smooth but corrugated and sage-like above, very downy 
beneath, pointed, often acuminate, at the end, rounded at base, 
on a short petiole. I take this to be S. recurvata of Pursh. 
It is a shrub six or eight feet high, with hght brown bark on 
the trunk, dark brown above, with a dark, clouded pubescence 
on the last year’s shoots. ‘The recent shoots are pale green, and 
somewhat pubescent. 
Leaves on short petioles, lanceolate or oblanceolate, usually 
broader towards the extremities, rather acute at each end, nearly 
entire, with a light, sulky pubescence above when young, after- 
wards smooth and shining, but strongly marked with depres~ 
sions at the veins and nerves; rugose and veiny beneath; revo- 
lute and waved on the margin; vernation revolute. Stipules 
about as long as the petiole, unequally ovate, pointed, some- 
times entire, often with one or two teeth on each side, downy. 
Aments appearing before the leaves and on distinct branches, 
the staminate half an inch long, often recurved, with two or 
three small leaves at base; scales rounded, brown, with thin, 
long, silken hairs, particularly on the edges; stamens two, on 
long filaments. Pistillate, one third to one half an inch, recurv- 
ed; scales dark brown, somewhat silky; germens ovate, closely 
covered with whitish, silky pubescence, supported on long pedi- 
cels, and tapering gradually to the bifid stigma.

Leaves oblong-lanceolate, remotely serrate, acute, smooth above, plain and 
downy beneath; recent shoots smooth; stipules lunate, somewhat dentate ; 
aments preceding the leaves, diandrous; scales lanceolate, obtuse, villous; 
ovaries stalked, lanceolate, silky; style bifid, stigmas bilobed.—Puvsh, II, 612. 
Branches blackish, the younger ones pubescent. Leaves oblong-lanceolate, 
acute, remotely. minutely and acutely serrate, very entire at base, above deep 
green, smooth, beneath plane, not rugose-veimed, softly tomentose, late in au- 
tumn nearly smooth. Leaf-stalks long. Stipules middle-sized, lunate, some-
