5. undulata Ehrh. Beytr., 6. p. 101., according to the specific character, but without inspection of 

 Ehrhartian specimens, Willd. Sp. 1'/., 4. p. <;r>. r >. ; ? ,S\ No. 38., Trcv. Obs. Bot., p. 18. ; and, as a 

 variety, S. lanceolata Smith Eng. But., t. 1136., according to an authentic English specimen. 

 Hooker has deemed identical with S. undulata of his Br. Fl.,ed. 3., p. 419., the kinds now to be 

 noticed: — S. lanceolata Smith Eng. Bot., t. 1436., Eng. Ft., and Forbes in Sal. Wob., No. 14. 

 "Dr. Meyler of Gottingen has sent me specimens of the S. undulata of Ehrh., compared with 

 the Ehrhartian herbarium ; and Mr. Borrer is satisfied that they are identical with Smith's S. 

 lanceolata; at least, with the Sussex specimens communicated by Mr. W'oollgar to him, and 

 which are probably the same with the females figured in Eng. Bot. Indeed, that station (viz. near 

 Lewes, in Sussex,) is the only one mentioned by Sir J. E. Smith as English. Mr. Borrer has 

 received German specimens of S. undulata 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, from 

 our present plant. {Brit. Ft., ed. 3., p. 419.) 



The Sexes. The female is figured in Sal. Wob , Nos. 13. and 14., and in Eng. Bot., t 1436. ; and 

 is described in Eng. Ft. Koch noted that he had seen the female wild and cultivated, but that he 

 had no knowledge of the male. 



Engravings. Sal. Wob., Nos. 13. and 14. ; Eng. Bot., 1. 1436. ; ? Hayne Abbild., 1. 160. ; our fig. 1296.; 

 and figs. 13 and 14. in p. 1605. 



Spec. Char., eye. Leaves lanceolate, acuminate through 

 much of their length, serrulate at the tip, and minutely 

 crenulate at the base ; at first pubescent, but becoming 

 glabrous ; wavy at the edge, or not. Stipules half-heart- 

 shaped. Catkin peduncled upon a leafy twiglet. Brac- 

 tea bearded at the tip. Stamens 3. Capsule ovate- 

 conical, more or less pubescent, or glabrous, stalked ; the 

 stalk twice the length of the gland. Style elongated. 

 Stigmas bifid. (Koch.) It inhabits the banks of streams, 1296 



in the plains and lower valleys in the north of German v, and in England.

Varieties. 



± & S. u. 2; S. undulata Forbes in Sal. Wob., No. 13.— Mr. Forbes 

 has 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 a 

 variety. Leaves linear-lanceolate, acuminate, somewhat attenuated 

 towards the base; wavy, and sharply serrated at their margins. 

 Ovary sessile, ovate, scarcely downy. Style about half the length 

 of the linear parted stigmas. (Sal. Wob., p. 25.) Cultivated in the 

 Dublin Botanic Garden, and flowering in April and May. It is an 

 upright-growing plant, soon forming a bushy tree, about 10 ft. or 

 12 ft. high, with brown, smooth, round branches, slightly downy 

 when young, and somewhat angular at the points. Catkins about 

 1 in. in length, bursting forth with the leaves. " This is a species 

 very distinct from the above, which is considered to be the S. undu- 

 lata of Ehrh art ; 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 the 

 Dublin Botanic Garden, from which I derived it." (Forbes in Sal. 

 Wob.) In relation to this kind, Mr. Borrer has remarked in his 

 list, that, " if S. undulata Forbes, and S. lanceolata Smith and Forbes, 

 the S. undulata Hooker, are to be regarded as two species, the former 

 agrees best with Ehrhart's character of his S. undulata." There 

 are plants in the Hackney and Goldworth arboretums, and at Wo- 

 burn Abbey, Henfield, and Flitwick House. 

 iiS. u. 3; S. lanceolata Smith Eng. Bot., t. 1436., Eng. Fl.,iv. 

 p. 168., Forbes in Sal. Wob., No. 14. — The following is Smith's 

 diagnosis 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. Fl.) Smith 

 has farther noted of its distinctive characters as follows: — "Akin to 

 S. triandra Liti. and S. Hoffmanniawa Smith. An essential means of 

 distinction exists in the leaves, which are longer and narrower than 

 those of S. triandra, or any ot % its reputed varieties ; more pointed 

 and tapering ; not linear, but truly lanceolate. Footstalks bearing
