(no. 63043, f.; N., O.; a young oe stage); Ranken Inlet, lat. 62°45’, 
August 30, 1910, J. M. Macoun (nos. 79163, 79165, 79166, fr.; Cor., N., O.; 
identical with type); Bathurst Tnlet: Arctic Sound, lat. 67° ms 68° N., long. 
tog’ to 111° W., August 25, 1915, R. M. Anderson (no. 467 or 93776 O., fr. im.; 
amentis satis laxifloris); Cape Eskimo, lat. 61° 05’, August 26, 1910, J. M 
Macoun (no. 79161, fr.; Cor., N., O.; forma foliis fructibusque majoribus, 
saltem in specim. in O., stomata superne in foliis ut videtur deficientibus) ; 
Mansfield Island, September 1884, R. Bell (no. 24622, fr.; O.; specimen 
mancum incertum). 
This is an interesting willow, and well marked in its typical form by the 
very short petioles of the small leaves, which are normally provided with 
stomata in the upper surface. It seems to be an entirely prostrate shrub with 
very slender creeping branches. Some of the forms I regard as S. fullertonensis 
or nearly related to it have been referred by RypDBERG to his S. Macounit, the 
type of which represents a very different plant, which I shall discuss under 
S. cordifolia. 
The following specimens look to me more or less like forms that 
might be taken for S. fullertonensis XS. groenlandica. They seem 
to differ from S. fullertonensis in the following characters: gemmis 
majoribus ad 5:3 mm. magnis, foliis latioribus ovato- vel obovato- 
ellipticis ovalibus vel obovato-oblongis apice saepe plicato, acutis 
basi rotundis ad late cuneatis adultis margine sparse ciliato excepto 
glabris superne magis nitidulo-viridibus (stomatiferis) subtus paullo 
distinctius nervatis reticulatisque maximis ad 2.8:1.5 cm. magnis; 
petiolis ad 4 mm. longis sed gemmas bene evolutas non superantibus; 
amentis fructiferis fructibusque vix diversis, bracteis late obovatis 
pl.m. longius et magis sericeo-pilosis; fructibus sessilibus vel pedi- 
cello distincto glandulam interdum superante suffultis, circ. 7 mm. 
longis. 
Hudson Bay: lat. 55-56°, barren shores, August 1886, J. M. Macoun 
(no. 18822, fr.; O.; ovariis sessilibus, bracteis sericeis, foliis distincte petiolatis, 
stomatiferis); Fullerton, September 4, 1910, J. M. Macoun (no. 79148 ir.; O-; 
79167, fr.; Cor., G., N., O.; forma foliorum ut in fullertonensi sed petioli 
longiores, stomata desunt, ovaria subsessilia, glandulae saepe 2, bracteae 
sericeae); Ranken Inlet, lat. 62°45’, August 30, 1910; J. M. Macoun (no. 79162, 
fr.; Cor., G., N.,O.; S. groenlandicae satis similis); Nottingham Island, 1884, 
R. "Bell (no. 18820" Cine 54358 O., fr. juv.; satis ad anglorum spectans sed 
sine stomata); Digges Island, 1884, R. Bell (no. 188203 olim,= 54359 9.5 
fragmentum, ut praecedens); Mansfield Island, 1884, R. Bell (no. 188205 olim, 
= 54360 O.; fr.; probabiliter ut praecedens); James Bay mouth of Albany
