ARBORETUM AND FRUTICETUM.

PART III.

green and downy on their upper surface; greyish, densely pubescent, anddenticulated with prominent arched veins beneath; the small ones nearlycovered 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 1 in. long. Thereare plants at Woburn, Flitwick, Henfield, and Hackney.

? Variety. Mr. Forbes received a kind of <S'alix, under the name of S.mollis, which, as compared with S. pannosa, had its leaf, catkin, ovary, andbractea larger ; and the catkins often recurved, and devoid of floral leaves.Mr. Forbes expresses himself doubtful whether it is sufficiently distinctfrom 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 pubescentabove ; pale glaucous and hairy beneath. Stipules rounded, serrated, andminute. 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 denselydowny, copiously beset with somewhat elliptical leaves, which are of a dullgreen colour above, pale and hairy beneath, with prominent veins, the sub-divisions of which form a rectangular network; their substance is ratherof a thin crackling texture ; the young leaves are very hairy in their earlieststate. There are plants at Woburn and in the Hackney' arboretum.

i 90. S. cine'kea L. Thegrep Sallow, or ash-coloured Willow.

Identification. Lin. Sp. Pi., 1449.; Willd. Sp. PI.,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 bis plant; Smith Eng. Rot., 1.1897.; Eng. FI., 4. p. 215.; Forbes in Sal Wob.,No. 125.; Hook. Br. FI., ed. 3. ; Maekay FI. Hibern., pt. 1: p.250.

Synonymes. S. cindrea var. Koch Comm., p. 36. The following information is derived from Mr.Borrer. Smith has erroneously cited, in his FL Br,, p. 1063., the S. tfaphnolde§ Villars as a syno-nyme of S. cindrea Smith ; and this has led Koch ( Comm ., p. 23.) to cite S. ein&rea Smith as asynonyme of S. rfaphnoldes Villars.

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

Spec. Char., §c. Stem erect. Lower leaves entire; upper serrated, obovate-lanceolate; glaucous, downy, and reticulated with veins beneath. Stipuleshalf-heart-shaped, serrated. Ovary silky; its stalk half as long as thelanceolate bracteas. (Smith Eng. FI.) A native of Eng-land, on the banks of rivers and in moist woods; andflowering, in the willow garden at Woburn Abbey, inApril, and again in September. The following descrip-tion is taken from the more detailed one of Smith in hisEnglish Flora : — “A tree, 20 ft. or 30 ft. high, if left toits natural growth ; but in hedges or thickets it is moredw'arf and bushy. It is readily to be distinguished fromother common willows, by its rusty glittering hue, whichlies more, perhaps, in the fine veins of its leaves, than inthe pubescence sprinkled over them, which consists ofminute, prominent, shining hairs, totally unlike the de-pressed silkiness of the species of the groups Glaucae,

Fuscae, and .ffosmarinifoliae. The rusty colour, indeed,increases after the specimens have been long dried, butis visible in some degree in the growing plant, especially towards theautumn. The branches are glabrous, reddish brown, and crooked; andthe young ones are slender, spreading, and, in an early state, downy. Onthe leafy branches of the year the lower leaves are nearly or quite entire,1 in. or l^in. long, obovate, with a short oblique point, on shortish slen-der footstalks, without stipules; the upper ones twice as large, variously
