REVISION OP THE BRITISH WILLOWS. 425 



glabrous. Leaves nearly orbicular, slightly cordate at the base, 





* 



slightly longer than broad (the largest about £ inch long); 

 margins more or less crenate-serrate ; surfaces bright pale green, 

 but not shining, slightly hairy with white woolly pubescence, more 

 especially on the margin ; veins pellucid, anastomosing, above 

 impressed (when young) or slightly raised (when old), below ele- 

 vated ; stipules minute, gland-like. Catkins (large lor the size 

 of the plant, being £ inch in length) rather lax-flowered, on lateral 

 peduncles which are furnished with one or two leaves ; scales 

 small, roundish, fuscous-brown but paler at the base, clothed with 

 long white hairs ; ovary lanceolate-conic, rather obtuse, glabrous 

 except at the extreme base and on the very short pedicel (thus 

 resembling some forms of S. herbacea) ; pedicel equal to or shorter 

 than the nectary ; style moderately long, slender, purple (which 

 colour occasionally tinges the ovary also) ; stigmas slender, 



bipartite. 

 The more recently found form was described when living. It 



makes a low plant, with flexuous slender rooting stems buried 

 amongst moss. Bark of the twigs rich but pale brown (becoming 

 dark when dried) or greenish brown, glabrous or slightly downy ; 

 young shoots greener and sparsely pubescent with long white 

 hairs ; buds rather long, oblong, blunt, at first green and hairy, 

 then brown and glabrous. Leaves wavy and half-folded, from 

 orbicular to oblong in shape (the largest l|xli inches); base 

 cordate, rounded, or slightly attenuated; tip often shortly pointed 

 and twisted; upper surface rather dark green and somewhat 

 shining, lower paler and subopaque, both with numerous minute 

 white dots, which disappear more or less in the dried plant; 

 youngest leaves more or less clothed with long white hairs, but 

 soon becoming glabrous; veins pellucid, reticulate, impressed 

 above (or slightly raised in the older leaves when dried) and 

 elevated below ; margin crenate-serrate, pinkish (as are the veins) 

 in the youngest leaves (this colour disappears in the dried plant) ; 

 stipules few, ovate, glandular-serrate. Catkins (the largest 1 inch 

 long) terminal on leafy stalks ; scales spathulate and involvent, 

 mostly pale and either scarcely or distinctly darker-coloured at 

 the apex, clothed with long white hairs ; ovary subulate, glabrous, 

 on a pedicel as long as or slightly shorter than the long thin 

 linear nectary ; style pale, long and slender ; stigmas long, bifid, 



spreading. 



Whilst in hoth of th fi «e forms the herbacea element is very per.
