THE BRITISH WILLOWS 75 



2-3 in. long by |-f in. broad, shortly peduncled, with 0-4 basal 

 leaves ; bracts oblong-obovate subobtuse, as in the $ clothed with 

 much long silky hair ; ovaries \-^ in. long including the long 

 styles, ovoid-subulate attenuate, glabrous, subsessile or lower ones 

 shortly pedicelled ; nectaries linear reaching above the base of the 

 ovaries ; stigmas small cleft or entire. 



This arctic willow occurs at an elevation of 2000-3000 ft. in 

 mountain corries of the Breadalbanes, Perthshire, sparingly, of 

 the Clova district (Glen Doll, Glen Fiagh, and Canlochan Glen), 

 Forfarshire, and in Glen Callater, Aberdeenshire, more plentifully.

X reticulata ? (p. 76). 

 It has also been crossed in the garden with S. repens (E. F. & 

 W. R. Linton, Nos. 99, 100), p. 76. 



Salix lanata x lapponum, hybr. nov. 



[Exclude S. lanata x lapponum Linton in Journ. Bot. 1891, 

 215, which proved to be a form of S. lapponum with large broad 

 leaf-blades.] 



A small shrub, 1-2 ft. high, with short stout branches villous 

 with loose subpersistent pubescence, becoming glabrous and dark 

 brown hardly shining by winter ; buds similarly pubescent during 

 the growing season, hardly glabrescent till the winter. Petioles 

 rather short, villous. Stipules foliaceous, oval, entire, grey-green. 

 Leaf-blades 1-2 in. long, oval-oblong shortly acuminate mostly 

 subacute, entire, softly pubescent on both sides, grey-green above, 

 almost silvery-green beneath, the earlier ones clothed all over 

 with long silvery hairs, which overlap the blade and form a 

 silvery margin. 



Foliage specimens only obtained, in 1897, from the same rocks 

 near the head of Glen Callater, from which came the broad-leaved 

 S. lapponum described in Journ. Bot. (I. c. supra). Its main 

 characters may be thus described : — 



Salix lanata x lapponum, hybr. nov. Frutex 1-2-pedalis 

 ramis villosis demum ad hiemem glabrescentibus ; stipulse ssepe 

 adsunt foliaceae ovales integrae ; petioli sat breves villosi. Folia 

 1-2 unc. longa oblongo-ovalia breviter acuminata ssepe subacuta 

 integra, molliter pubescentia, in novellis pilis argenteis infra 

 longe crinita. 



This plant, probably $ since no catkins survived, is nearer to 

 S. lapponum in the shape of the leaf-blades, but differs from that 

 species in the stouter branches, larger buds, in the long silvery 

 hair clothing the leaf-blades beneath, persistent in the earlier 

 ones, and in the foliaceous stipules present on the young shoots, 

 such as S. lapponum never produces with us. 



One or two plants among many of S. lapponum fringing the 

 top of the cliff near the head of Glen Callater, Aberdeenshire, a 

 little in the direction of Coire Ceannder.
