SOME NEW WILLOWS OF EASTERN AMERICA. 
M. L. FERNALD. 
REcENT explorations of the eastern portion of the Province of Quebec 
have brought to light many willows which have hitherto been unknown 
in eastern America. Some of these shrubs, such as Salix pseudo- 
myrsinites Anders., S. Barclayi Anders., and S. fuscescens Anders., 
have been previously known only from the northwestern Provinces 
or from Alaska; the unique S. Richardsoni Hook., var. Macouniana 
Bebb has been known only from Hudson Bay and northern Labrador; 
while some others it has been impossible to identify with any described 
species or varieties. 
The most abundant of these undescribed willows are two large shrubs 
or small trees which abound on the terraces and banks of the St. 
Lawrence at least from Matane to the River Ste. Anne des Monts, 
and probably beyond, and for several miles inland in the valley of 
that river. One of these trees, which in its best development is about 
15 feet high, with wide-spreading branches, has the largest leaves 
known to the writer in any member of the Diandrae, the mature blades 
often reaching a length of 5 or 6 inches. This handsome large species 
may appropriately be called
