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

 denticulated with prominent arched veins heneatli ; tlie small ones nearly 

 covereil with pubescence ; the margins serrated, entire towards the base j 

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

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

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



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

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

 bractea larger ; and the catkins often recurved, and devoid of Horal leaves. 

 Mr. Forbes expresses himself doubtful whether it is sufficiently distinct 

 from S. pannosa to constitute a distinct species. 



S 89. S. muta'bilis Forbes. The changeable Willow, or Sallow. 



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

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



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

 above ; pale glaucous and hairy beneath. lSti|)ules 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. (AW. 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.

Identification. Lin. Sp. PI., 1449. ; Willd. Sp. PI, 4. p. 690., exclusively of the syn. ofVillars; 

 Smith in Rees's Cyclo.,No. 94., where Smith has remarked that Willdenow's description disagrees, 

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

 No. 125. ; Hook. Br. Fl., ed. 3. ; Mackay Fl. Hibern., pt. 1. p. 250. 



F.ynonynies. S. cinerea var. Koch Comm., p. 36. The following information is derived from Mr. 

 Borrer. Smith has erroneously cited, in his Fl. Br., p. 1U63., the S. rfaphndides f't/lars as a syno- 

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

 synonyme of S. rfaphnoides I'illars.

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

 lanceolate.; glaucous, downy, and reticulated with veins beneath. Stipules 

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

 lanceolate bracteas. {Smith Eng. Fl.) A native of Eni;- 

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

 flowering, in the willow garden at Woburn Abbey, in 

 April, and again in September. The following descrip- 

 tion is taken from the more detailed one of Smith in his 

 Engllth Flora : — "A tree, 20 ft. or W ft. high, if left to 

 its natural growth ; but in hedges or thickets it is more 

 dwarf and bushy. It is readily to be distinguished from 

 other conunon willows, by its rusty glittering hue, which 

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

 the pubescence .sprinkled over them, which consists of 

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

 pressed silkiness of the species of the groups Glaucae, 

 Fuscaj, and /?osniarinif61iae. The rusty colour, indeed, 

 increases after the specimens have been long dried, but 

 is visible in some degree in the growing plant, especially towards the 

 autumn. The branches are glabrous, reddish brown, and crooked ; and 

 the young ones are slender, spreading, and, in an early state, downy. On 

 the leafy branches of the year the lower leaves are nearly or quite entire, 

 I in. or \ ^ in. long, obovate, with a short oblique point, on shortish slen- 

 der footstalk:?, without stipules ; the upper ones twice as large, variously
