THE WILLOWS OF OHIO. 311 



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 5. glaucophylla and rather larger than the average of 

 5". cor data. 



In typical forms the wooly broad leaves will distinguish it 

 from everything else in our area. It is sometimes difficult to 

 separate, however, from 5. cordata in its more tomentose forms, 

 and intermediates seem to occur. In shape the leaves are not so 

 different from 5. 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 5. 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 5. 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 5. 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 5. 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 gloss}' leaves cannot but 

 suggest that species.
