Branches slender, procumbent or ascending, bark dark brown, 

 rather shining ; fresh twigs and buds pubescent, becoming glabrous. 

 Stipules present on strong shoots, ^-cordate to roundish-reniform, 

 serrulate. Leaf-blades f-l£ in. (3-4 times as long as the stalk), 

 roundish, rounded or subcordate at the base, rounded above or 

 with short twisted acute tip, serrate, pale dull green below, soon 

 glabrescent. Catkins J-f in. long, on short pubescent leafy 

 peduncles, fl. May ; bracts narrow oblong obtuse, subglabrous, 

 ciliate, pale, tipped with light red ; ovaries ovate-conic white- 

 pubescent ; nectaries oblong, sometimes bipartite, pedicels about 

 three times as long ; stigmas bifid, about as long as the short

Dwarf bush, 2-3 ft. high (in cultivation), much branched, 

 branches ascending, pubescent, soon glabrescent, bark dark brown 

 + shining, buds woolly-pubescent at first, at length glabrous. 

 Stipules much suppressed, |-cordate-acuminate when well deve- 

 loped. Leaf-blades 1-2 in. long, obovate- or oval-acuminate, or 

 oblong-lanceolate, narrowed to the base or to both ends, more 

 rarely oval subobtuse, broad or narrow, tip usually acute, often 

 twisted ; grey or grey-green, softly pilose or woolly-pilose, sooner 

 or later glabrescent ; subentire but commonly obscurely serrate or 

 crenate-serrate, often undulate at the margin. Catkins flowering 

 in April usually rather before the leaves, with dark-brown shining 

 bud-scales ; $ 1 in. long, oval-oblong ; 2 1-1| in. long, silvery- 

 grey to grey-green ; bracts oblong or obovate-oblong subacute or 

 obtuse, clothed with long silky hairs ; pedicels at length longer 

 than the linear-oblong nectaries ; styles long, stigmas short or 

 medium. 



The leaves of this hybrid are generally more like those of 

 S. lapponum than of S. aurita, only rather greener and more 

 obovate ; in one form, however, from Glen Shee, the leaves are 

 more like S. aurita, and much greener than the average of inter- 

 mediate specimens. 



In Scotland it is known from Edinburgh, Perthshire (Mid and 

 East), Forfarshire, and East Inverness. Europe : East Prussia, 

 Scandinavia, Finland, Russia.
