Tree 2-6 m. high, the larger trunks 1—1.5 dm. in diameter, with 
the nearly plane scarcely rugose leaves becoming 1 dm. long in 
maturity; mature pistillate aments very large, 2.5—3 em. thick; pedi- 
cels 5-8.5 mm. long; capsules 9-12 mm. long.— QUEBEC, abundant 
on banks of the St. Lawrence from Rimouski Co. to Gaspé Co. ‘Type 
material: limestone ledges, Bic., July 4—6, 1906 (Fernald & Collins, 
nos. 208, 495). 
Along the gravelly half-inundated margin of the River Ste. Anne 
des Monts occurs an unusually attractive little shrub, its slender 
smooth branches rarely more than 2 or 3 feet high and its short oblong 
or suborbicular dentate leaves suggesting to the casual observer the 
foliage of the common Amelanchier spicata (Lam.) C. Koch. (A. 
rotundifolia Roem.) of the region, rather than that of any of our wil- 
lows. Prolonged study fails to show any American willow to which 
it is nearly related, but in foliage as well as in its sessile aments the 
shrub very strongly suggests the little known Siberian Salix pyrolae- 
jolia Ledeb. as shown in Ledebour's beautiful plate. From that 
unique species the shrub of the Ste. Anne River differs in several 
important characters enumerated below, and it seems sufficiently 
distinct to merit the name : 
SALIX obtusata n. sp. Frutex parvus, ramis gracilibus castaneis 
glaberrimis; foliis oblongis vel terminalibus suborbiculatis 2-5 cm. 
longis 1-3 em. latis dentato-serratis apice rotundatis basi rotundatis 
vel subcordatis junioribus arachnoideis tenuissimis pellucidis pur- 
purascentibus demum coriaceis glabris supra viridibus subtus pallidi- 
oribus, petiolis gracilibus 5-12 mm. longis; stipulis cordatis persisten- 
tibus majoribus 5 mm. longis obscure glanduloso-dentatis; amentis 
sessilibus, femineis 5-20 mm. longis; squamis oblongo-ovatis obtusis 
subfuscis laxe villosis; capsulis glabris conico-subulatis rufescentibus 
vel flavescentibus 2-3 mm. longis breviter pedicellatis, pedicello 
nectarium valde superante; stylo parvo, stigmatibus minimus bifidis. 
Low slender shrub (0.5-1 m. high): branchlets slender, glossy 
brown, glabrous: leaves oblong to suborbicular, 2-5 cm. long, 1-3 
em. broad, closely dentate-serrate, rounded or subcordate at base, 
rounded at apex, glabrous, or the youngest arachnoid-tomentose, at 
first thin and purple-tinged; later coriaceous, bright green above, 
slightly glaucous beneath; .petiole slender, 5-12 mm. long: stipules 
cordate, persistent, the largest about 5 mm. long, obscurely glandular-
