A shrub with stems 2-12 ft. high, branching from the base, 

 branches glabrous or often slightly pubescent at first in Britain, 

 at length dark brown and polished ; buds narrow, pointed, 

 yellowish, glabrous or quickly glabrescent. Stipules infrequent, 

 small, cordate-acuminate when well developed. Leaf-blades 1-3 in. 

 long, oval, oblong-acuminate, or oblong-obovate to -lanceolate, 

 ± acute, serrate or crenate-serrate (teeth not crowded), subentire 

 near the base and at the tip, green and shining above, glaucous or 

 grey-green beneath (often green near the tip), glabrous theoretically 

 but often somewhat pubescent at the very first in Britain, firm 

 and becoming coriaceous, not blackening when dried. Catkins 

 usually subsessile with few small basal leaves, preceding the 

 foliage ; bracts oblong to obovate, acute or subacute, + hairy ; 

 $ 1 in. long, filaments glabrous, anthers yellow ; ? 1-2| in. long, 

 elongate, at length lax, peduncles pubescent ; ovaries pubescent to 

 tomentose (rarely glabrous) ; pedicels pubescent elongate, at length 

 3-4 times as long as the quadrate or shortly oblong nectaries ; 

 styles long, usually longer than the large stigmas. 



The varieties of £. phylicifolia in Syme E. B. and former 

 editions of the London Catalogue were described as species by 

 Sir J. E. Smith and others, but have latterly been reduced to mere 

 synonyms of S. phylicifolia or its hybrid with S. Andersoniana, 

 since it has come to be recognized how variable these two species 

 are, and how numerous are the variations of the hybrid between 

 them. 



Since S. phylicifolia has normally pubescent ovaries, glabrous 

 filaments, and a leaf with an entire tip, the following are best 

 regarded as synonyms, forms which vary only in the shape of the 

 leaf-blade : — S. radicans Sm., S. Davalliana, and S. tenuior Borrer, 

 with blades oblong-acuminate or obovate-acuminate to oblanceo- 

 late ; S. Weigeliana Willd., and S. Crowcana Sm. (pr. pte.), 

 having leaf-blades which are broadly or narrowly oval, and rather 

 subacute than acuminate ; of these S. Croweana has its filaments 

 connate near the base. Of the forms described with glabrous 

 ovaries, S. phillyreifolia Borrer seems to be true S. phylicifolia ; 

 so does S. Borreriana Sm. $ ; but the $ plant of the latter 

 and S. tenuifolia Sm. $ and $ for the most part are S. Ander- 

 soniana x phylicifolia, except the Kirby Lonsdale plant, which 

 Borrer saw was a form of "S. bicolor of Hooker's Brit. Flora," 

 i. e. S. laurina Sm. (see Journ. Bot. 1904, Suppl. pp. 185, 187) ; 

 and this is what the specimen in hb. Smith appears to be. Leefe's 

 No. 68, "received from Borrer as S. tenuifolia," differs from
