224 Rhodora [DECEMBER 
dentate: aments sessile upon the old wood, the pistillate short-cylin- 
dric, 0.5-2 cm. long: scales oblong-obovate, obtuse, brownish, loosely 
villous: capsule glabrous, conic-subulate, reddish or yellowish, 2-3 
mm. long: pedicel 0.5 mm. long, much exceeding the very short 
nectary: style very short, the stigmas bifid; staminate aments not 
seen.— QUEBEC, inundated gravelly bars and beaches, River Ste. 
Anne des Monts, fruit July 15, 1906, mature foliage August 16, 1906 
(Fernald & Collins, nos. 203, 203a). 
Closely allied to and strongly simulating the Siberian S. pyrolaefolia 
Ledeb. but differing in its more shallowly toothed leaves, shorter 
sessile aments and very short style. The type specimens were col- 
lected from characteristic low shrubs associated with a number of 
other willows — S. cordata, S. pellita, S. glaucophylla, &c.— at the 
frequently inundated margins of a group of alluvial islands near the 
head of the Grand Rapids of the River Ste. Anne des Monts. 
Salix fuscescens Anders., hitherto known only from northern and 
western Alaska and the adjacent coast of Siberia, is abundant in bogs 
on the serpentine tableland of Mt. Albert. It is a very attractive 
creeping shrub, in foliage and other characters strongly suggesting 
S. pedicellaris Pursh of our northern temperate regions (S. myrtilloides 
of American authors, not L.). From the lowland species, S. fuscescens 
is quickly distinguished by its usually obovate leaves, the more pubes- 
cent scales of the aments, the very short thickish pedicels (barely 
exceeding the scales), the long subulate nectary which is usually half 
as long as the pedicel, and the definite though short style. As stated, 
this attractive species is abundant in the bogs of Mt. Albert, where it 
is associated with numerous other plants typical of western and north- 
ern Alaska and adjacent Siberia — Eriophorum C hamissonis C. A. 
Meyer, Conioselinum Gmelini (C. & S.) Coulter & Rose, Festuca 
altaica Trin., &c.,—— and although many colonies have the capsules 
quite glabrous as in the type of the species, others occupying extensive 
areas of bog, have the capsules distinctly pilose. These shrubs with 
pilose capsules seem otherwise identical with typical S. fucescens and 
they may be designated 
SALIX FUSCESCENS Anders., var. hebecarpa n. var. Frutex parvus, 
ramis subflagelliformibus; foliis amentisque eis formae typicae simili- 
bus; capsulis pilosis. 
Capsules pilose; characters otherwise as in the typical form.—

1906 (Fernald & Collins, no. 207).
