mens from the same source were secured by Mr. Williams, Dr. H. L. 

 Robinson, and the writer. The foliage of the Fort Kent tree was 

 very long for S. /ui-/W(7' and tiie under surfaces of the leaves, espe- 

 cially along the veins, were pubescent with persistent rufous hairs. 

 A comparison made by the writer of this material and an authentic 

 sheet of Andersson's .V. hicidiU var. uuu-rophyUa led him to identify 

 the Fort Kent tree with Andersson's variety from British Columbia. 

 Subsequently, however, the pubescent-lea\ed extreme has been 

 watched in northern Maine and Quebec, particularly upon the upper 

 St. Francis where it abounds, and a more detailed examination 

 shows that it cannot well be treated as identical with the British 

 Columbian willow with which it was at first placed. 



Salix liicida, var. macrophyUa, as shown in the Gray Herbarium by 

 a specimen of Lyall's from the Lower Frazer Kiver, has the ample 

 young leaves glaucous and glabrate beneath, though minutely pubes- 

 cent on the midrib above, and it is apparently a phase of the extreme 

 western ^'. lasiaiidra, Benth. The northern Maine willow which was 

 once referred by the writer to S. hicida, var. macrophylla^ proves 

 upon further study to differ very constantly in having the leaves 

 green and not glaucous beneath and permanently pubescent on the 

 nerves beneath with sordid or rufescent hairs. This plant with per- 

 manent pubescence is found to vary in size from a small shrub of 

 cold swamps, with mature leaves only 4 or 5 cm. long, to well devel- 

 oped trees of rich alluvium, with leaves often 15 cm. in length. 

 Kxcept in the abundance and permanence of the pubescence there 

 seems no other character by which to separate the northern Maine 

 willow from narrow-leaved forms of glabrous or early-glabrate S. 

 lucida\ but as a variety with marked geographic range it is worthy 

 separation as 



Salix luciha, Muhl., var. intonsa. Shrub or small tree, rarely 

 becoming 7 or 8 m. high with trunk 1.3 dm. in diameter: branches 

 of the first year pubescent with mostly permanent sordid or rufes- 

 cent hairs: mature leaves elliptic-lanceolate, taper-pointed, 4 to 15 

 cm. long, I to 3.5 cm. broad, permanently pubescent, especially on 

 the veins beneath. — -V. Inrida. var. JiuurophyUa, Fernald, according
