348 BOTANICAL GAZETTE [OCTOBER 
This variety needs further observation. It seems to be the prevailing one 
on Anticosti Island and in northwestern Newfoundland. Some more vigorous 
forms from Blanc Sablon and Forteau with more distinctly denticulate leaves 
might also be referable to it. RypBERG’s type is a very glabrous specimen 
collected in September. Forms from Hopedale in Labrador (Sornborger, 
no. extra 1) and northern Ungava (A. P. Low, no. 24769 O.) are rather uncer- 
tain. Specimens like no. 3207 have the mature leaves entirely glabrous 
(except a few hairs on the margin), as in the type, while the young parts show 
a more copious pubescence similar to that of S. cordifolia typica. 
There are other specimens which I cannot determine properly 
and which are worth further observation: 
Newfoundland: Ingornachoix Bay, Pointe Riche, limestone 
barrens near sea level, August 4, 1910, Fernald and Wiegand 
(no. 3204, fr.; G.), forma foliis pl.m. orbicularibus ‘vel elliptico- 
rotundis satis ad var. Macounii spectans, fere ut in var. typica 
pilosa, sed floribus femineis glandula satis lata (fere ut in groen- 
landica) instructis et fructibus pedicello quam glandula sublongiore 
suffultis laxe puberulis, stylis brevibus stigmatibus brevibus bifidis 
vix longioribus, bracteis obovatis substramineis breviter pilosis.— 
Quebec: Saguenay County, Archipel Ouapitagone, Ile Matchiatik, 
sprawling on ledge, July 15, 1915, H. St. John (no. 90841 O., f.; G.), 
praecedente non absimilis. 
A very uncertain form has been found by St. John on the Mingan 
Islands, Ile au Marteau (Eskimo Island), top of limestone shingle, 
July 28, 1915 (no. 90837 O., m., f.; G.): ramulis novellis perspicue 
dense albo-tomentosis, foliis semi-evolutis obovato-ellipticis ad 
5:2.5 cm. magnis costa ex parte petioloque excepto glabris superne 
in epidermide stomatiferis inferioribus ut in f. hypoprionota den- 
ticulatis, stipulis semiovatis denticulatis glabris, floribus ut in 
S. cordifolia sed bracteis apice interdum leviter fuscis. 
Lastly, there remains to be discussed a willow from western 
Greenland which seems most closely related to S. cordifolia, but 
which also considerably resembles S. anglorum, and has apparently 
been referred by most of the authors to S. glauca. I cannot include 
it among any of the species previously mentioned, but deem it best 
to propose a new species.
