THE BRITISH WILLOWS 35 



since only one sex is known. It occurs in a few Midland counties 

 from Norfolk and Suffolk to Staffordshire ; also in Dumbarton- 

 shire, and formerly in co. Edinburgh. Owing to confusion with 

 allied hybrids, other records are doubtful. On the Continent its 

 occurrence is doubtful outside botanic gardens.

A small compact shrub, 1-5 ft. high, branching from the base, 

 branches ascending pubescent at first, glabrous by winter, dark 

 brown shining ; buds ovoid obtuse woolly-pubescent dark brown, 

 flower-buds large, often yellowish-brown in winter, with sub- 

 persistent pubescence. Stipules 0, or minute, fugitive. Leaf- 

 blades 1-2^ in. long, broadly oblong or obovate-oblong, rarely 

 narrow-elliptic or lanceolate, acute or acuminate (lower often 

 obtuse), entire sometimes undulate, cuneate to rounded at the 

 base, seldom subcordate, softly pubescent and grey-green to dark- 

 green above with veins impressed, white- to grey-tomentose 

 beneath, veins visible. Catkins appearing before the leaves, June, 

 July, subsessile with few very small peduncular leaves ; bracts 

 oblong or obovate-oblong obtuse or more commonly subacute, 

 villous with long silky hair; $ catkins oval, 1 in. long, filaments 

 glabrous, anthers yellow or reddish at first ; ? 1-2 in. long, rather 

 close-flowered, rachis woolly ; ovaries -|— T 3 o m - l° n g> white with 

 pubescence then grey-green, ovoid-conic, subsessile (lower ones 

 becoming shortly pedicelled) ; nectaries linear, long, nearly 

 reaching the broadest part of the ovaries ; stigmas long, usually 

 divided, hardly as long as the long styles. 



S. lapponum varies in the breadth and length of the leaf-blades 

 and in their clothing, but the various forms pass gradually into 

 one another. Smith describes a greener form with leaves less 

 clothed as S. arenaria, adopting a name which Linnaeus had given 

 to a mixture of S. lapponum and S. repens argentea forms; and a 

 form with more woolly leaves as S. Stuartiana. The latter may 

 be the same as Wimmer's b. marrubiifolia (Sal. Eur. p. 41). 



A more distinct variety is that which Smith described as 

 S. glauca (S. lapponum var. pseudo -glauca Syme), and which Dr. 

 B. White (Revision, p. 428) has well argued is the same as 

 S. helvetica Vill. (Hist. Plant. Dauph. p. 783). If the specimen 

 in the Edinburgh Univ. Herb, labelled " Salix glauca, Ben 

 Lawers " by Winch — which is S. glauca Sm., i. e. S. helvetica 

 Vill. — really came from Ben Lawers, this variety, or subspecies, of
