THE WILLOWS OF OHIO. oll 
generally accompanied by large stipules. The flowers differ 
from those of our other species of cordatae in having broader 
bracts, much woolier before anthesis; in fruit by the denser cat- 
kins with shorter pedicelled capsules which are smaller than 
those of S. glaucopiylla and rather larger than the average of 
S. cordata. 
In typical forms the wooly broad leaves will distinguish it 
from everything else in our area. It is sometimes difficult to 
separate, however, from S. cordata in its more tomentose forms, 
and intermediates seem to occur. In shape the leaves are not so 
different from S. bebbiana but they will be quickly distinguished, 
among other things, by the sharply serrate margins of the present 
species. 
Salix adenophylla is our rarest willow. It is a plant of the 
Western Great Lake region and reaches its best development in 
Michigan, being rare east of that state. Until recently it was 
not supposed to extend into Ohio but I have seen several speci- 
mens collected at Erie, Pennsylvania. It should therefore ex- 
tend the whole length of the Ohio Lake Shore. But it is very 
scarce indeed. Though I have hunted for it on Cedar Point and 
in Ashtabula County I have seen from Ohio but a single undoubt- 
ed specimen which was taken by A. D. Selby on Cedar Point. 
SALIX GLAUCOPHYLLA Bebb. BROAD—LEAVED WILLOW. 
A shrub sometimes 5 m. tall, growing in clumps like S. cor- 
data; leaves mostly broad, ovate or ovate-lanceolate, shiny above 
except in rank growth, with very fine irregular venation and 
stiff midribs which hold them up at an acute angle with the stem 
so as to display the white under surfaces. In character the leaves 
resemble much the narrower leaves of S. petiolaris and like them, 
when succulent have a strong tendency to blacken in drying. 
Flowers appearing before the leaves, bracts mostly narrow, glau- 
cescent; staminate aments generally larger than those of S. cor- 
data with smaller bracts; carpellate long, lax in fruit, capsules 
very long (1 cm. or more) glabrous, sometimes rostrate, long ped- 
icelled, turning brown. 
Bebb labelled some of the first material of this species he 
sent out, Salix cordata x S. lucida. This determination though 
very far from correct as he himself soon recognized, is descriptive 
of the species. Its affinity to Salix cordata is evident at once 
from inspectoin of either leaves or flowers but yet in both there 
is a strong resmeblance to Salix lucida. The large thick catkins 
with the long capsules and the beautiful glossy leaves cannot but 
suggest that species.
