BUDS AND STIPULES. 253 
The fourth leaf is oblong and more narrowed to the base. The 
fifth leaf is lanceolate ; and the sixth and seventh are very similar. 
The eighth leaf is more decidedly narrowed to the base, and 
when in situ is more completely rolled round the bud than the 
previous ones, and almost entirely covering it. It will be seen 
that there is little difference between the lengths of the first 
eight leaves. The ninth, tenth, and eleventh leaves are very 
similar to the eighth, but much shorter and smaller. The 
stipules are large, particularly on the leafy shoots; but they 
„develop after the leaves are expanded, or during that process. 
Some forms are exstipulate. 
In Salir cinerea, Linn., the winter-buds are ovoid, short, 
ancipitous or strongly but obtusely carinate laterally, that is right 
and left. The scale has a slight ridge along the centre of the 
posterior aspect, and this splits to the base as the buds expand in 
spring. "The anterior face becomes notched or merely emarginate 
at the same period. The stipules are minute and inconspicuous 
in bud, but ultimately develop to large size. 
8. pyrifolia, Anders., has the winter-buds short, ovoid, dorsally 
compressed, but biconvex, carinate on the two lateral edges, not 
ridged on the posterior face. The scale splits along the posterior 
face, but not always to the base. The anterior face splits about 
halfway down. The scale splits more than halfway down the 
dorsal aspect, then it splits cireumferentially by a fairly even line 
tl the upper portion is only held by a narrow shred, and in this 
position it clings to the axis for some time. The lower portion 
forms a cylinder round the axis, but is barst at last by the 
swelling of the latter, and the whole scale in this torn condition 
falls away. The leaves are oval in bud, densely woolly on the 
back and downy on the face. 
E cordata, Muhl.— Winter-buds relatively long, narrow, sub- 
Ne, obtuse, obtusely carinate laterally, with a wide, shallow 
toe ae along the dorsal aspect. The scale splits to the base on 
face . " aspect, but merely becomes emarginate on the anterior 
fice of th m this condition soon falls away bodily. The inner 
like an ne scale often splits away from the outer, and appears 
small in "ur very membranous scale. The stipules are very 
arger on ud, but develop to fair size as growth proceeds. The 
dular der es are more or less cordate or half-cordate, and glan- 
itate or denticulate.
