ovaries. (Hook. Br. FI., p. 417.) A native of Scotland,on the Clova Mountains, and also near Dumfries ; growing vto the height of 1 ft., and flowering in April. Botanists Rare not agreed as to what is precisely the S. arbuscula L. 11Smith deemed it to be this; but Mr. Forbes (Sal. Wob.,

No. 86., and incidentally under No. 138.) and Mr. Borrer «NUIr(Hook. Br. FI., ed. 2.) have concluded that it is not. Mr.

Forbes was much inclined to regard it as not specificallydistinct from S. rosmarinifolia Eng. FI. and Eng. Bot.; |and Mr. Borrer, or Sir W. J. Hooker, or both, have regardedit as probably the same as the S. angustifolia Wutfen. As to its relationto S. rosmarinifolia, Sir W. J. Hooker says, “ I agree with Mr. Borrer inthinking that they are distinct, though the difference lies almost entirely intheir ovaries: these are shorter in S. angustifolia, with denser, less glossy,and less truly silky hairs, with ovate and quite entire stigmas, and moreshaggy bracteas. There are plants at Woburn and Flitwick.

SO. S. decu'mbens Forbes. The decumbent Willow.

Spec. Char., §c. Leaves linear-lanceolate, nearly entire; dull green and silkyabove, pale and densely silky beneath. Stipules lanceolate. Branchesdowny. Ovary ovate, silky, nearly sessile. Style elongated. Stigmasdivided. (Sal. Wob., p. 175.) A native of ? Switzerland. Introduced in 1823,and flowering in May. A small shrub, with leafy downy branches, extendingobliquely from the ground to the height of 1 ft. or 1 ft. 6 in. The leaves arefrom I Jin. to 2 in. long, or more; linear-lanceolate, entire, or nearly so,some of them marked with a few glands about the middle; dull green andsilky above, beneath densely silky ; the young ones have somewhat a silveryappearance underneath. Buds red before expansion. Catkins nearly 1 in.long. A very distinct species, resembling in foliage the male plant ofS. rosmarinifolia.

at 51. S. fusca'ta Pursh. The dark-brown-branched Willow.

Identification. Pursh FI. Amer. Sept., 8. p. 612. ; Smith in Rees’s Cyclo., No. 110.

The Sexes. The female is noticed in the specific character.

Spec. Char., fyc. Leaves obovate.lanceolate, acute, somewhat serrated; glaucous beneath, downywhen very young. Stipules minute. Catkins drooping. Bracteas (scales) obtuse, scarcely hairyon the inside. Ovary ovate, silky, somewhat stalked. Wild in North America, in low overflowedgrounds on the banks of rivers, from New York to Pennsylvania ; flowering in March or April.Branches of the preceding year covered with a dark brown or black tomentum. ( Pursh and Smith.)Introduced in 1811.

Group xi. Fiiscce Borrer.

Mostly procumbent Shrubs.

—

Stamens 2 to a flower, as far as to the kinds whose male flowers have beenobserved. Ovary silky, stalked. Catkins ovate or cylindrical. Leavesbetween elliptical and lanceolate; mostly silky beneath; nearly entire.Plants small shrubs. Stem, in most, procumbent. S. fusca L., Hooker,var. 1., and S. Don iiina Smith, have a likeness in aspect to the kinds of thegroup Purpureas, except S. rubra Huds. (Hook. Br. FI., ed. 2., adapted.)
