Exs. Hb. Linn. No. 68a. Hb. Smith (" Salix elliptica nov. sp. 

 Clova Mountains, Mr. Thos. Drummond, Mr. W. Robertson, 

 1825 "). E. F. & W. R. Linton, Nos. 75. Enander, Nos. 25, 

 26, 28, 29, 31, 34-39. 



A dwarf decumbent shrub, rarely suberect, with slender 

 branches pubescent at first, sooner or later glabrescent, at length 

 dark brown and often polished. Stipules 0. Leaf-blades |-1| in. 

 long, usually oval or oval-oblong, sometimes roundly oval, sub- 

 acute, or more often obtuse or rounded at the tip, subcordate, 

 rounded or ovate at the base, subentire, crenate or crenate-serrate, 

 pubescent at first, often + glabrescent ; veins often impressed 

 above. Catkins coeval with the leaves, fl. June-July, on 3-4- 

 leaved pubescent peduncles ; bracts obovate and rounded above, 

 more rarely obovate-spathulate obtuse, turning brown or some- 

 times reddish upwards, rather thinly pubescent, ciliate with silky 

 hairs ; $ catkins £—£ in. long, slender or (in one form) rather 

 broadly ovoid-oblong ; $ 2~li m * l° n g> dense-flowered, seldom 

 lax even at the base ; ovaries ovoid-conic or sometimes shortly 

 ovoid, sessile or lower ones pedicelled, tomentose at first, often 

 becoming thinly pubescent ; pedicels usually pubescent and shorter 

 than the linear nectaries, lower ones sometimes exceeding them ; 

 styles long or at least longer than the moderate stigmas. 



A monoecious form occurred in Glen Fiagh, with ^ and £ 

 catkins J-J in. long, the ovaries also of small size and crowded 

 together. 



S. J. Enander describes in his Exs. several forms and subforms, 

 which show much variation in the clothing of the ovaries as well 

 as other characters. Our forms, varying in leaf-characters, bracts 

 and pedicels, are fairly constant in the ovaries being covered with 

 whitish pubescence at first, which thins out as the capsule ripens. 



S. herbacea x lapponum has been found on Meall na Saone, 

 in Glen Tilt, and on the Glen Lyon side of Meall Garbh, in 

 Perthshire, in the Clova district, chiefly in Glen Fiagh, Forfar- 

 shire, and sparingly, in Glen Callater, Aberdeenshire. S. J. Enander 

 issues or records it from several localities in Norway and Sweden.

A dwarf shrub with decumbent stems, branches slender pubes- 

 cent at first, at length glabrous. Stipules 0. Leaf-blades oval- 

 oblong, rounded or cordate at the base, obtuse or acute, serrate 

 (with erect teeth) or crenate-serrate, rather coriaceous, green and 

 glabrescent above with the veins often impressed, paler green and 

 pubescent beneath, with long silky deciduous hairs on the earlier 

 leaves, veins raised opaque often reddish. Catkins $ about \ in. 

 long, appearing with the leaves in June, on pubescent 2-3-leaved
