1918] SCHNEIDER—AMERICAN WILLOWS 129 
“S. arctica, Fort Franklin, Mackenzie River.’ It contains male 
and female branchlets with young flowers and very young, narrowly 
lanceolate, rather acute leaves. So far as I can judge by the thinly 
pubescent and distinctly pediceled ovaries, by the oblong bracts, 
and by the absence of a dorsal gland in the male flowers, the speci- 
men does not belong to S. anglorum, but may probably be referable 
to S. groenlandica Ldstr. Furthermore, RYDBERG states that his 
S. anglorum “‘is characterized by . . . . the exceedingly large cat- 
kins, which are rather loosely flowered below, and the large conic 
capsule, which is only moderately hairy.’”’ If we compare this 
statement and the specimens cited by RypDBERG, his misinterpre- 
tation of BRown’s species is evident. RypBERG refers to his S. 
anglorum mostly specimens that in reality belong to S. groenlandica, 
about which species he certainly had a very wrong idea. - 
Almost simultaneously with RypBERG (May 1899), BALL pub- 
lished a statement regarding S. arctica and Begs’s treatment of this 
species. He knew Lunpstr6m’s study, but overlooked S. anglo- 
rum Cham.; he said, however, ‘‘I shall not rename the plant now, 
for I believe the name which has been in use for 80 years (S. arctica 
R. Br.) can yet do duty until both the numerous variations and the 
synonymy have been given careful study.” In Brirron and 
Brown’s Ill. Fl. (ed. 2. 1:605, fig. 1489. 1913) the name S. an- 
glorum is applied to forms from ‘‘Labrador to Alaska, and-in the 
Rocky Mountains to Colorado’ in a way I do not understand. 
Judging by the ample material before me, S. anglorum seems 
more variable than S. arctica. The habitat of the northeast Ameri- 
can plant ranges from Northwest Greenland (about Disco Island) 
and Labrador (where it apparently does not occur south of the 55th 
parallel) through northern Ungava along the Hudson Strait and the 
northern shores of the Hudson Bay to the Franklin Bay, reaching, 
as it seems, its most western point at Cape Bathurst and not ranging 
beyond 130° W. longitude. There are some forms collected on 
Herschel Island (coast of Yukon Territory) which might be taken 
for S. anglorum, but on account of the absence of stomata in the 
upper surface of the leaves I refer them to S. arctica. Between 130° 
and 140° W. longitude there may be the meeting ground for the 2 
Species, and we need much more and well collected material from
