THE WILLOWS OF OHIO. Oe 
more sharply pointed and never pubescent. While both have a 
bloom on the under surfaces, S. longipes is gray glaucous and 
S. amygdaloides bluish glaucous. Besides all this their ranges 
do not overlap in Ohio. 
In fruit it is easily distinguishable from either of the other 
Amygdaleneae. The capsules are similar to those of S. nigra 
but larger and long pedicelled like those of S. amygdaloides. 
SALIX AMYGDALOIDES Anders. PEACH-LEAVED WILLOW. 
Salix amygdaloides grows to medium sized or rarely to a 
large tree. Its bark and general appearance suggest at once its 
affinity for the black willow of which it was once considered a 
variety. Its habit, however, differs very considerably from 
that of Salix migra. It is generally single-stemmed and very 
shapely, with clean branches and darker brown, smoother bark. 
The winter buds are nearly twice as large as those of Salix nigra, 
dark brown above with a much lighter base where they were pro- 
tected by the petiole of the old leaf in the fall. Salx amygda- 
loides is well-named for when in leaf the tree, at a little distance, 
often bears a striking resemblance to a peach tree; the twigs and 
petioles are often reddened and the leaf arrangement is similar to 
that of a peach tree. Both twigs and leaves are entirely devoid 
of hairs while young shoots, at least, of the other black willows 
are pubescent. 
The leaves are much broader than in the other members of 
the amygdalenae, often being almost ovate, distinctly broadest 
below the middle with a rounded base and an attenuate falcate 
tip, bright green above, glaucous beneath. The venation while 
of the black willow type begins to approach the regular type, ex- 
emplified by S. alba; the primaries are close, the marginal vein 
short, hardly extending as far as the middle of the leaf, and 
the meshwork, though very fine is much coarser than in Salix 
nigra, while the secondaries are often more or less regular. 
The catkins are so similar to those of the black willow that 
it is difficult to distinguish them in dried specimens. With the 
carpellate aments the difficulty disappears in fruit but with the 
staminate it continues in old flowers. The brightening of the 
bark at flowering time, which is noticeable in all willows renders 
the twigs in Salix nigra very similar to those of the present species 
. and its smaller buds are swollen to about the size o those of the 
Peach-leaved willow so that they can be used as a diagnostic 
character no longer. The leaves supporting the catkins are too 
young to have assumed their characteristic texture and the 
aments themselves are almost the same. But Salix amygdalot- 
des flowers nearly two weeks earlier than Salix nigra, which to- 
gether with the habits should distinguish them in most cases.
