There proved to be some other equally interesting forms in the 
Same swamp. They are our nos. 21, 23,28 and 84. Everything 
Seems to point to these being hybrids between Salix candida and 
S. cordata. 
No. 21 at time of flowering might easily be mistaken for pure 
Salix cordata. Itis a staminate plant and has the large catkins and 
general aspect of S. cordata. The catkins are “sessile” as in S. 
candida. The young leaves are comparatively smooth, but even 
in age retain the “ candida” characteristics very decidedly. The 
venation of the leaf resembles that of S. candida more than it does 
that of S. cordata. The leaves are lanceolate-acuminate as in S. 
cordata. The petioles are twice the length of the small stipules. 
The gall which is so abundant upon SS. cordata in this region is 
abundant also upon this plant. 
No. 23 is a pistillate plant. The capsules in the mature catkin 
{collected May 17) are acute and still bear the rather long style. 
ey are sparsely tomentose and green and the sutures upon their 
Sides are conspicuous. The leaves when young are densely-to- 
mentose on both sides, the mature ones are whitened below and 
very veiny, those upon the lower part of the shoot being very 
sparingly tomentose, tapering nearly equally both ways and acute 
at both ends. The petioles are not longer than the stipules. The 
stipules are rather large, obliquely, very broadly ovate, acute and 
revolute. The winter buds are ovate, acutish, but rounded at the 
apex, divergent and only slightly flattened. The whole plant 
Seems to be intermediate between its supposed parents. 
No. 28 also a pistillate plant, is closely related to S. cordata. 
If it were not for the rugose, slightly revolute inconspicuously 
toothed, and somewhat tomentose leaves, the long styles and spar- 
ingly tomentose capsules, it would be at once so considered. The 
capsule becomes green and nearly smooth at maturity, but retains 
somewhat the form of the “candida” capsule. The form of the 
leaves and stipules, the leafy peduncled catkins, and the size of the 
plant are all suggestive ot S. cordata. The winter buds also re- 
semble those of the pistillate plants of S. cordata 
No. 84 is also a pistillate plant. It bears a close resemblance 
to S. candida. In fact during our first visits to the swamp we a 
took this plans to belong unquestionably to oy species and did as
