220 ENGLISH DOTANY. 



seen only dried and cultivated specimens, so I follow ^Ir. Borrer's 

 description in " Engl. 13ot." Suppl. : — " Shrub 6 feet liigli or a little 

 more branched from the base. Branches procumbent at their origin, 

 then upright, strjiight and wandlike at iirst, afterwards producing 

 numerous small twigs, silky while very young, soon denuded, of a 

 greenish ash colour, sometimes tinged with purple, old bark grey, not 

 so remarkably yellow within as in the monandrous species, buds red, 

 slightly downy. Leaves on short broadish foot-stalks, some of the 

 lower ones in pairs, the rest spirally scattered." Largest leaves 1 to 

 l}y inch long, shaped like those of S. purpurea, but with the texture 

 and reticulation, when dry, of those of S. repens, at first more or less 

 thickly clothed with shining silky hairs, which soon disappear from the 

 upper surface, and partially from the lower. Female catkins ^ to 

 ^ inch long. Catkin-scales purplish, nearly black at the apex, shorter 

 than the capsules. Capsules silky white, blunt at the apex. 



On the Continent the male catkins have been found, and are about 

 f inches long, the anthers are at first reddish, afterwards becoming 

 fuscous; the filaments united from the base for about three parts of 

 their length. 



Wimmer mentions a form in which the capsules are glabrous. In 

 his specific description he gives " germina . . . sessiUa," but this 

 seems to be a misprint, as in the detailed description he states: 

 '• germina ... in pedicello J germinis longitudine." He says it is a 



shrub 2 to 3 feet hmh.

Leaves alternate, rarely subopposite, strapshaped-elliptical or oblong- 

 elliptical, broadest near the middle or a little beyond it, acute or 

 acuminate or oblong-oblanceolate, very faintly and bluntly serrate, 

 brio-ht green, smooth, and rather glossy above, paler or glaucous 

 beneath, at length generally glabrous on both sides, rarely silky-hairy 

 beneath* Stipules lanceolate, often absent. Catkins opening before 

 the leaf-buds expand; the male catkins subsessile, with small non- 

 foliaceous bracts at the base, cylindrical, thick, dense, at first erect, 

 afterwards spreading, recurved-spreading; female catkins rather thick, 

 dense, suberect, with a few foliaceous bracts at the base. Catkin- 

 scales oval-oblanceolate, blunt, pilose. Stamens 2, with the filaments 

 combined only at the bas6, or united to the ai:)ex, pilose at the base.
