BUDS AND STIPULES. 255 
Salix stipularis, Sm.—Buds lanceolate or narrowly ovoid, ob- 
tusely and faintly carinate laterally. Winter-scale bursting to the 
base posteriorly, and slightly bifid at the apex anteriorly. Leaves 
broadly lanceolate. Stipules linear-lanceolate, very small in bud. 
S. phylicifolia, Linn., var. Weigeliana, Willd.—Buds ovoid, or 
oblong, more or less flattened, strongly carinate laterally. Winter- 
scale usually bursting to the base posteriorly, and varying from 
emarginate to bifid anteriorly. Many of the scales burst 
throughout their length on the anterior face, but such scales are 
generally crippled or dead, and often contain the grub of a moth. 
The leaves are also crippled, and have a difficulty in getting clear 
of the scale. Stipules small, and involute at the edges long after 
leaving the bud. Some of the scales burst at the apex and 
some at the base, but all appear to be crippled by insects or 
otherwise. 
S. alba, Linn.—The winter-buds of the White Willow are 
all axillary; the terminal one as well as the tip of every shoot 
dies. The buds are oblong, obtuse or subacute, compressed. 
antero-posteriorly, but tumid on the anterior face (fig. 109), 
thickened at the edges, and have a thickened suture (fig. 109 a) 
along the middle of the posterior aspect. The cap-like outer 
and only scale, owing to its thickened edges, might seem to 
consist of two leaves united, and the strong, slightly branched 
nerve easily seen on the inner face of these thickened edges 
tends to support this view; but no suture is discernible on the 
anterior face. When growth recommences in spring, the scale 
bursts along the suture on the posterior face (fig. 10% b). 
When the tip of the scale dies in winter, it breaks off during 
the bursting of the bud; and when the whole of it dies the 
growing leaves rupture it at its insertion on the stem. 
SA true leaf (fig. 110) is ovate, flattened on the pos- 
v tace against the axis, incurved at the sides, and covering 
o-thirds of the bud. The dorsal face is silky, but the inner 1s
