green and downy on their upper surface; greyish, densely pubescent, and 

 denticulated with prominent arched veins beneath; the small ones nearly 

 covered with pubescence ; the margins serrated, entire towards the base; 

 tip oblique. Many of the leaves are opposite or nearly so, and alternate, 

 on the same branch. Footstalks stont. Catkins about 1 in. long. There 

 are plants at Woburn, Flitwiek, Henfield, and Hackney. 



f Variety. Mr. Forbes received a kind of Salix, under the name of S. 

 mollis which, as compared with S. panndsa, had its leaf, catkin, ovary, and 

 bract ea larger ; and the catkins often recurved, and devoid of floral leaves. 

 Mr. Forbes expresses himself doubtful whether it is sufficiently distinct 

 from N. pannosa to constitute a distinct species. 



a 80. S, MUTa'bilis Forbes. The changeable Willow, or Sallow. 



Identification. Forbes in Sal. Wob., No. 160. 

 The Sena. The female is described in Sal. Wob. 



Spec Char., cSr. Leaves elliptic, remotely serrated ; dull green and pubescent 

 above ; pale glaucous and hairy beneath. Stipules rounded, serrated, and 

 minute. Ovary stalked, ovate-lanceolate, silky. Style somewhat elon- 

 gated and stout. Stigmas cloven. It bears an affinity to S. pannosa in cat- 

 kins and mode of growth. (Sal. Wob., p. 288.) A native of Switzerland. 

 Introduced in ? 1824, and flowering in March and April. Branches densely 

 downy, copiously beset with somewhat elliptical leaves, which are of a dull 

 green colour above, pale and hairy beneath, with prominent veins, the sub- 

 divisions of which form a rectangular network; their substance is .rather 

 of a thin crackling texture; the young leaves are very hairy in their earliest 

 state. There are plants at Woburn and in the Hackney arboretum. 



1 90. S. cine v rea L. The grey Sallow, or ash-coloured Willow. 



Identification. Lin. Sp. PI., 144H. ; Willd. Sp. PI., 4. p.690., exclusively of the syn. ofVillars; 

 Smith in Rees's C'yclo., No. !>4., where Smith lias remarked that Willdenow's description disagrees, 

 in Mine points, with his plant ; Smith Eng. Bot., 1. 1897. ; Eng. Fl., 4. p. 215. ; Forbes in Sal Wob., 

 \ ! .. ; Hook. Br. El., ed. 3. ; Maekay Fl. Hibern., pt. 1. p. 250. 



Synoni/i/irs. S. cinerea var. Koch Coram., p. .%'. The following information is derived from Mr. 

 Borrer. Smith has erroneously cited, in his Fl. Br., p. 1063., the S. rfaphnoides Villars as a syno- 

 nyme of .S\ einerea Smith ; and this has led Koch {Comm., p. 23.) to cite S. cinerea Smith as a 

 synonyme of V. (/aphnbides Villars. 



The Seres. Both sexes are figured in Sal. Wob. The male is figured in Eng. Bot.

Spec. Char., Src. Stem erect. Lower leaves entire ; upper serrated, obovate- 

 Lanceolate ; glaucous, down}', and reticulated with veins beneath. Stipules 

 half-heart-shaped, serrated. Ovary silky; its stalk half as long as the 

 lanceolate bracteas. (Smith Eng, Fl.) A native of Eng- 

 land, on the banks of rivers and in moist woods; and 

 flowering, in the willow garden at Woburn Abbey, in 

 April, and again in September. The following descrip- 

 tion i-i taken from the more: detailed one of Smith in his 

 / 7/.v// Flora : — " A tree, 20 ft. or 30 ft. high, if left to 

 natural growth ; but in hedges or thickets it is more 

 dwarf and bushy. It is readily to be distinguished from 

 Other common willows, by its rusty glittering hue, which 

 lief more, perhaps, in the fine veins of its leaves, than in 

 the pubescence sprinkled over them, which consists of 

 minute, prominent, shining hairs, totally unlike the de- 

 pressed lilkiness of the species of the groups Glaucae, 

 I i . and ffosmarinifoliae. The rusty colour, indeed, 



increases after the Specimens have been long dried, but 



is risible in orae <\<'jr<-c. in tint growing plant, especially towards the
