1:46. 1905), which name is adopted byRYDBERG (Fl. Rocky Mts. 

 198. 191 7), although he says "perhaps not distinct from the eastern 

 S. vestita Pursh." It certainly cannot be distinguished specifically, 

 and if we intend to apply a special denomination to the more erect 

 form with rather "thinner, narrower, rounded or pointed leaves," 

 we have to use the name var. erecta And. (in DC, Prodr. 16^:300. 

 1868). The aments are usually longer than in the eastern form, 

 but there are specimens before me from Alberta (Ig. Rehder and 

 also Jack) with the same short fruiting catkins. Professor 

 Fernald kindly pointed out that the shape of the capsules of typical 

 vestita is more ovoid-conical, with a rather pointed apex, while it is 

 more ovoid-ellipsoid, with an obtuser apex, in var. erecta. There 

 seem to be rather intermediate forms, but as a whole this character 

 may be taken for the best one to distinguish these eastern and 

 western forms. 



Another form has been collected by Fernald and St. John in 

 western Newfoundland which seems closely connected with the 

 next species, but its description has not yet been published and it 

 needs further observation. 



3. S. LEiOLEPis Fernald in Rhodora 16:178. 1914.— This is a 

 very peculiar species, which was discovered by Fernald and St. 

 John on the Table Mountain, Port a Port Bay, in western New- 

 foundland, July 17, 1914, on "mossy knolls on the limestone table- 

 land, alt. 200-300 m." (no. 10825, fr.; G.). In habit and foliage 

 it closely simulates, as the author said, S. reticulata and the most 

 dwarfed alpine extreme of S. vestita; but it differs "from both in the 

 glabrous scales and capsules; also from 5. reticulata in its short 

 peduncles and thick fruiting aments, and from S. vestita, which is the 

 most abundant willow of Table Mountain, in its glabrous or quickly 

 glabrate foliage and the smaller and more slender, glabrous, greenish 

 terminal buds." As the type specimen shows, the ovaries are 

 sometimes sparsely pubescent, the bracts frequently provided with 

 a few cilia, the styles very short but more or less distinct, and even 

 the old leaves bear some hairs on the lower surface which are often 

 rather difficult to recognize. Unfortunately the male sex is still 

 unknown; consequently I cannot decide whether S. leiolepis is to be 

 regarded as a good species or as a glabrate variety of S. vestita,
