256 GREY WILLOW: BAY WILLOW 



Oaprea, var. cinerea, Grey Willow (Fig. 135). A 

 variety or sub-species of the group 8. Caprea and S. 

 aurita, the hoary shoots inclining to dark fuscous, rather 

 robust, with shallow rills at the tips, and soft to the touch 

 owing to the dense grey tomentum on buds and tips, 

 passing to smooth. Intermediate between 8. Caprea and 

 8. aurita, and with similarly shaped and disposed buds. 

 The twigs are, however, thinner and more branched, 

 and the buds smaller and more nodulose. 



ZZ Buds and twigs glabrous, 

 though the tips of the shoots 

 may be slightly pubescent. 



> Buds and twigs polished 

 broion, as if varnished, and 

 quite glabrous. 



S. pentandra, L. Bay Willow. Buds erect, more or 

 less appressed, ovoid, the upper larger than those to- 

 wards the base of the shoot, and reminiscent of S. Caprea; 

 bud-scales polished brown, or the base greenish. Colour 

 of twigs passing into green. 



[S. pentandra, L., is said by Bentham to have green or 

 yellow twigs. Its upper buds are reminiscent of S. Caprea, 

 but they are browner. It presents difficulties also with 

 S. triandra, the twigs of which tend to be more angular 

 above, and the buds to be more pubescent. Buchanan 

 White has indicated some confusion between this plant 

 and S. fragilis, L., and it may be doubted whether the 

 points of difference furnished by the polished brown 

 twigs can be. relied on.] 



> > Buds red, or tawny yellow 

 with reddish flecks, convex. 



S. Caprea, L. Sallow (Fig. 136). Twigs nodose with 

 projecting leaf-bases, and leaf-scars large for a willow ;
