Wob., No. 14.“Dr. Meyler of Gottingen has sent me specimens of the S. undulkta of Ehrh.,compared withthe Ehrhartian herbarium 3 and Mr. Borreris satisfied that they are identical with Smith’s S.lanceolata; at least, with the Sussex specimens communicated by Mr. Woollgar to him, andwhich are probably the same with the females figured in Eng. Bot. Indeed, that station (viz. nearLewes, in Sussex,) is the only one mentioned by Sir J. E. Smith as English. Mr. Borrer hasreceived German specimens of S. undul&ta with silky germens; and these are probably the S’, un-dulata of Salict. Wob., which differs only in that respect, and in its more wavy leaves, fromour present plant. {Brit. FI., ed. 3., p. 419.)

The Sexes, The female is figured in Sal. Wob , N os. 13. and 14., and in Eng. Bot., t. 1436.; andis described in Eng. Ft Koch noted that he had seen the female wild and cultivated, but that hehad no knowledge of the male.

Varieties.

1 at S. m, 2; 1 S', undulata Forbes in Sal. Wob., No. 13. — Mr. Forbeshas given the following specific character, or diagnosis, of this kind,he treating it as a species ; and, as this character may serve to por-tray its main features, we retain it in application to it, viewed as avariety. Leaves linear-lanceolate, acuminate, somewhat attenuatedtowards the base; wavy, and sharply serrated at their margins.Ovary sessile, ovate, scarcely downy. Style about half the lengthof the linear parted stigmas. (Sat. Wob., p. 25.) Cultivated in theDublin Botanic Garden, and flowering in April and May. It is anupright-growing plant, soon forming a bushy tree, about 10 ft. or12 ft. high, with brown, smooth, round branches, slightly downywhen young, and somewhat angular at the points. Catkins about1 in. in length, bursting forth with the leaves. “ This is a speciesvery distinct from the above, which is considered to be the S. undu-lata of Ehrhart ; from which it is readily distinguished by long,taper-pointed, wavy leaves. I conceive it to be a foreign kind.I have not observed it in any collection but that contained in theDublin Botanic Garden, from which I derived it.” (Forbes in Sal.Wob.) In relation to this kind, Mr. Borrer has remarked in hislist, that, “ if /S. undulata Forbes, and S. lanceolata Smith and Forbes,the S. undulata Hooker, are to be regarded as two species, the formeragrees best with Ehrhart’s character of his S. undulata.” Thereare plants in the Hackney and Goldworth arboretums, and at Wo-burn Abbey, Henfield, and Flitwick House.

5 at S. u. 3 ; S. lanceolata Smith Eng. Bot., t. 1436., Eng. FI., iv.p. 168., Forbes in Sal. Wob., No. 14. — The following is Smith’sdiagnosis of this kind:—Leaves lanceolate, serrated, glabrous,taper-ing towards each end. Footstalks decurrent. Ovary stalked, ovate,glabrous. Styles as long as the stigmas. (Smith Eng. FI.) Smithhas farther noted of its distinctive characters as follows :—“Akin toS. triandra Lin. and S. Hoffmannwroa Smith. An essential means ofdistinction exists in the leaves, which are longer and narrower thanthose of 5. triandra, or any of its reputed varieties; more pointedand tapering; not linear, but truly lanceolate.
