truly British ; but there seems no reason why, like several other willows, 

 it may not grow wild in Europe as well as in North America ; and the au- 

 thorities above mentioned are not likely to be erroneous." (Smith.) " I have 

 never seen native specimens." (Hooker in JBr. Fl.) 



& 44. S. PENNSYLVA'NICA Forbes. The Pennsylvanian Willow. 



Identification. Forbes in Sal. Wob., No. 95. 



Synonymes. ? Is not this the same as S. petiolaris Smith ; or, perhaps, it is the S. griseaff i/W. (Borrer 

 in a letter.) In Sweet's Hort. Brit., ed. 1830, it is questioned if S. pennsylvamca Forbes be not iden- 

 tical with S. pedicellris of Spreng. Syst., which is the S. pedicellaris Pursh. 



The Sexes. The male is described and figured in Sal. Wob. 



Engravings. Sal. Wob., No. 95. ; and OUT fig. 95. in p. 1620. 



Spec. Char., $c. A bushy shrub. Leaves alternate, lanceolate, serrated ; 

 smooth, glabrous, and shining above ; densely clothed beneath with silky 

 silvery hairs. Stipules very minute, soon falling off. Catkins of the 

 male nearly 1 in. long, slender. Bractea oblong, hairy. Gland obtuse. 

 This kind, in its whole form and habit, bears a strong likeness to S. petiolaris 

 Smith ; but the silvery silkiness of the old leaves perfectly distinguishes 

 it. (Sal. Wob., p. 189.) A native of ? North America; flowering in 

 April. Introduced in (?) 1825. A low spreading shrub, with yellowish 

 green, round, villous, brittle branches. Leaves lance-shaped, varying from 

 3 in. to 5 in. in length, sometimes nearly 1 in. broad ; dark green and 

 shining above ; beautifully silvery-silky beneath ; all the leaves of a thin 

 texture; midrib pale, prominent, and slightly villous. Footstalks scarcely 

 i in. long. Catkins appearing before the leaves, nearly sessile. Anthers 

 reddish before expansion; afterwards yellow. There are plants in the 

 Goldworth Arboretum, and at Woburn Abbey and Flitwick House.
