the leaves, cylindrical, villous. Bracteas ovate, acute. Stamens 3 to 5, 

 bearded half-way up. Branches extremely brittle at the base. (Pursh.) 

 A native of Virginia and Carolina. In the salictum at Woburn, it is a low- 

 growing shrub, with slender, roundish, smooth, yellowish branches, rising 

 about 3 ft. or 4ft. high ; flowering in May and June. " This species," Pursh 

 observes, " so frequently found in gardens under the name of S. tristis, is 

 very far from being in any way related to it. The specimen in the Banksian 

 herbarium was collected by Houston, and, as it is said, in Vera Cruz ; but 

 I am confident that it is a more northern plant, as I have frequently seen it 

 in Virginia." (Fl. Amer. Sept., ii. p. 614.) There are plants in the Gold- 

 worth Arboretum, and at Woburn Abbey, Henfield, and Flit wick House ; 

 also in the arboretum at Hackney, under the name of S. tristis.

Spec. Char., fyc. Leaves very long, linear-lanceolate, closely serrated, tapering gradually, and some- 

 what falcate upwards ; acute at the base ; glabrous on both surfaces ; when young, silky. Stipules 

 crescent-shaped, toothed, deflexed. A very smooth species, with very slender brown branches ; 

 flowers not yet observed. {Pursh.) A native of North America, from Pennsylvania to Virginia,

 seen the plant.

 The Sexes. Both sexes are described in Willd. Sp. PL, and in Bees's Cyclo. : they are more briefly 



noticed in the specific character below.

Spec. Char., fyc. Petiole long, silky. Disk of leaf lanceolate, acuminate, serrulate ; glabrous on the 

 upper surface, silky on the under one. Stipules linear. Stamens 2. Ovary silky, oblong. Stigmas 

 sessile, obtuse. (Willd. and MUhlenb.) Wild in marshes in Pennsylvania. A shrub of man's 

 height. Branches brown, downy when young. Disk of leaf l£in. long. Catkins protruded earlier 

 than the leaves. (Willd.) Introduced in 1820. 



Variety. 



& S. g.2 glabra. — Glabrous. Koch considers this the same as the S. petiolaris of Smith, de- 

 scribed below, No. 43. ; and asserts that it is not a native of Britain, though Smith has 

 included it in his English Flora.

 Synonymes. S. grisea Willd. var. /3 subglabrata Koch Comm., p. 21., note*. Koch regards the 

 ' S. petiolaris Smith as a var. of S. grfsea ; and it probably is so. (Borrer in a letter.) 

 The Sexes. The female is figured in Eng. Bot. and Sal. Wob. Smith observes that he " knows 



nothing of the male plant." (Eng. Fl.) Mr. Borrer had formerly both sexes growing at 



Henfield, having received the male from Mr. G. Anderson, but at present he has the female 



only. (W.B.)

Spec. Char., Sf-c. Leaves lanceolate, serrated, glabrous ; glaucous beneath, some- 

 what unequal at the base. Stipules lunate, toothed. Catkins lax. Bracteas 

 hairy, shorter than the stalks of the ovate silky ovaries. Stigmas divided, 

 sessile. {Smith Eng. Fl.) A native of Scotland, in An- 

 gusshire and other places; forming a bushy tree, with 

 slender, spreading, flexible, smooth, purplish, or dark brown 

 branches ; flowering in April. It is easily known from every 

 other species, by its short obtuse catkins, and long dark 

 leaves. After gathering, the young leaves especially exhale 

 a strong scent, like the flavour of bitter almonds, but less 

 agreeable. No use has been made of this willotv, though 

 it seems to abound in tannin. (Smith in Eng. Fl.) " Sent 

 from Scotland by the late Mr. Dickson. In Possil Marsh, 1319
