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 stout. Catkins about lin. long. There 
are plants at Woburn, Flitwick, Henfield, and Hackney. 
? Variety. Mr. Forbes received a kind of Salix, 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 floral leaves. 
Mr. Forbes expresses himself doubtful whether it is sufficiently distinct 
from S. pannosa to constitute a distinct species. 
& 89. S.muTa’BILIs Forbes. The changeable Willow, or Sallow. 
Identification. Forbes in Sal. Wob., No. 160. 
The Sexes. The female is described in Sal. Wob. 
Spec. Char., §c. 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.

Identification. Lin. Sp. Pl., 1449.; Willd. Sp. Pl. 4. p.690., exclusively of the syn. of Villars ; 
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., t.1897.; Eng. Fl., 4, p.215.; Forbes in Sal Wob., 
No. 125.; Hook. Br. Fl., ed. 3. ; Mackay Fl. Hibern., pt. 1. p. 250. 
Synonymes. S. cinérea var. Koch Comm., p.36. The following information is derived from Mr. 
Borrer. Smith has erroneously cited, in his #7. Br., p. 1063., the S. daphndides Villars as a syno- 
nyme of S. cinérea Smzth ; and this has led Koch (Comm., p. 23.) to cite S. cinérea Smith asa 
synonyme of S. daphnoides Villars. 
The Sexes. Both sexes are figured in Sal. Wob. The male is figured in Eng. Bot. 
Engravings. Eng. Bot., t. 1897. ; Sal. Wob., No. 125. ; our jig. 1332.; and fig. 125. in p. 1626. 
Spec. Char., Sc. 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 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 is taken from the more detailed one of Smith in his «3 
English Flora: — “ A tree, 20 ft. or 30 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 common 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, prominent, shining hairs, totally unlike the de- 
a sta silkiness of the species of the groups Glaticz, 
Gscz, and Rosmarinifoliz. The rusty colour, indeed, 
increases after the specimens have been long dried, but !332 
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, 
lin. or 14in. long, obovate, with a short oblique point, on shortish slen- 
der footstalks, without stipules; the upper ones twice as large, variously
