of the plant. All the leaves are more or less falcate; their falca- 
tion varies greatly on the same plant. 
A hybrid between S. nigra and S. alba has been reported 
from New York.* It is said to have the catkins of S. alba and 
the leaves of S. nigra x amygdaloides. Such a cross 1s most 
surprising in view of the distant relationship of the parents. It 
has not been reported from Ohio. 
SALIX LONGIPES Shuttlew. Warpb’s WILLOW. 
This species has not as yet been found in the state; its near- 
est reported station is at the falls of the Ohio at Louisville. 
Though this is some distance south of our territory it is possible 
that it may be found along the Ohio River. I include it here be- 
cause of that possibility and in order to make the paper more 
useful outside the state. Its range extends from Missouri to 
Washington, D. C., and southward to the Gulf. Dr. Glatfelter 
says that it is not found like S. migra sometimes away from the 
banks of the streams but is strictly confined to them. 
Sometimes it grows into a tree like S. migra but much more 
bushy. Around Washington it is a low shrub resembling S. 
cordata surprisingly, considering the remoteness of their relation- 
ships. The leaves have short stout petioles which with the mid- 
ribs and larger veins are usually hairy. The blades are extreme- 
ly variable. Frequently in rank growth they are auriculate at 
the base; this character when present segregates them at once 
from any other of our species. Sometimes they are very long, 
oblong-lanceolate with straight edges narrowing gradually to the 
tip; and this again is like no other of our species. More often 
they are lanceolate with upper surfaces varying from shiny and 
glabrous to dull and hairy. Sometimes they resemble those of 
S. nigra closely except for the glaucous under surface. Or they 
may be so similar to those of S. cordata as to deceive even the 
expert; often this resemblance is especially well borne out by the 
under surface which is at times gray glaucous and hairy exactly 
like that species when grown in a dry place. The two can best 
be distinguished by the venation which is similar to that of the 
rest of the Amygdaleneae except that the marginal 1s hardly per- 
ceptible and in its place the primaries ascend a long way near the 
margin. 
From printed descriptions Salix amygdalotdes might be ccn- 
fused with the present species but they are nct very similar. 
Salix amygdaloides is a much cleaner more shapely tree, never 
shrubby; its leaves are long petioled, decidedly broader, much
