THE BRITISH WILLOWS 13 



Leicester, a few years ago, there were twenty-two named sorts in 

 cultivation, of which " Pomeranians," " Councillor," and " Black 

 Maul" were commended as the best. Subsp. Hoffmanniana was 

 not noticed among these, being probably too " spriggy," a bad defect 

 in an osier. Europe generally ; Asia in the Caucasus, Armenia, 

 Persia, Turkestan, China, and Siberia.

Var. a, hippophaefolia (Thuill.). 



A large riverside shrub with glabrescent twigs and buds. 

 Stipules ovate- to cordate-lanceolate. Leaf-blades 3-5 in. long, 

 linear-lanceolate but with some variation in length and breadth, 

 obscurely serrulate or crenate-serrate, dark green somewhat 

 shining above, paler green beneath, pubescent at first but soon 

 glabrous, margin reflexed, vernation revolute. Catkins 1 in. long ; 

 stamens 2, sometimes 3 ; $ elongating to 1| in. ; bracts ovate- 

 oblong obtuse villous, nearly as long as the finely pubescent 

 ovate-conic (at length broadly ovate) ovaries ; pedicels about as 

 long as the narrow oblong nectaries ; styles and stigmas about 

 equal. 



A curious monoecious form, distributed by the Rev. A. Ley, 

 from near Ross-on-Wye, has stamens and ovaries mingled together 

 on each catkin. 



S. hippophaefolia is grown in the Thurmaston holts, under the 

 name of " Black Tops," and considered a very good osier. 



Var. f3, Trevirani (Sprengel). 



Syn. S. Trevirani Sprengel, Pug. i. 61 (1813). Wimmer, Sal. 

 Eur. 114. — S. triandra x viminalis B. White, Revision, 357. 



Icon. Forbes, Sal. Wob. t. 14 (as S. undulata Forbes, non 

 Ehrh.). 



Exs. Wimmer, Sal. Relict. (Herb. Sal. 113, 115 ; Coll. Sal. 

 249-251). 



S. Trevirani differs from S. hippophaefolia Thuill. chiefly in 

 being on a larger scale with broader and more attenuate leaf- 

 blades more glabrous from the first, larger catkins and glabrous 

 ovaries. It is nearer S. triandra, as y S. mollissima Ehrh., 

 which Andersson makes a third variety of this hybrid, is nearer 

 S. viminalis. Dr. B. White thought that the Herefordshire and 

 Staffordshire $ specimens (I. c. p. 357) belonged to x S. Trevirani. 



S. hippophaefolia, to which all our $ plants undoubtedly 

 belong, occurs in seven counties, from Gloucester and Glamorgan
