1498 ARBORETUM AND FRUTICETUM. PART III. 



at the summit a pair of glands, or minute leaflets ; not abrupt at the 

 base, but decurrent, each meeting with a projection of the branch, 

 tapering downward, and forming a kind of buttress ; which character 

 is clear and invariable." (Ibid.) There is a plant of S. lanceolata 

 in the Botanic Garden, Twickenham; and there are also plants 

 in the Hackney and Goldworth arboretums, and at Henfield and 

 Flitwick House. Mr. Forbes observes that this sort deserves cultiva- 

 tion, as the rods are much used for hampers, crates, &c. although 

 not so well adapted for tying bundles, and for the finer sorts of 

 wicker work, as the S. triandra.

 case. (Koch Comm.,p. 20.)

S. Aippophaefblia Thuil. is so similar to S. undulata, as to be, perhaps, but a variety of that species. 



(Borrer in a letter.) 

 The Sexes. Both are noticed in the specific character. 



Spec. Char., $c. Leaf lanceolate, obsoletely crenulate in a repand manner ; 

 toothed with glanded teeth, so small as to seem to consist of glands only ; 

 acuminate through much of its length, downy, eventually glabrous. Stipules 

 half-heart-shaped. Catkin borne on a leafy peduncle, which is a twiglet. 

 Bractea hairy. Stamens 2. Capsule ovately conical, tomentose, downy, 

 or glabrous ; seated on a stalk that is as long as the gland. Style long. 

 Stigma bifid. (Koch.') Wild in the plains and lower valleys of the Pala- 

 tinate, Wetteravia, Silesia, and the north of Germany. Treviranus thinks 

 that this is the true S. undulata of Ehrhart ; " but I," say^s Koch, " have 

 not been able to find any of its leaves undulated, among many specimens 

 observed growing wild; but, perhaps, Ehrhart included this in his S. 

 undulata, to which it is too near akin to be a species distinct from that."

Spec. Char., fyc. Leaves linear-oblong, serrated, glabrous, rather unequally 

 sloping at the base. Stamens 3. Ovary stalked, ovate, compressed, gla- 

 brous. Stigmas nearly sessile. (Smith E. Fl.) Bractea (or scale) clothed 

 externally with fine, long, spreading, more or less plentiful hairs. (Ibid.) 

 Bractea glabrous. (Hook. Br. Fl., 3d ed.) Mr. Woollgar used to distin- 

 guish this species by the dark-barked smooth shoots of the female plant. 

 The male one he never met with at Lewes. (Ibid.) A native of Britain, 

 in wet woods and osier grounds, where it forms an upright tree, rising 

 naturally, when not injured, to the height of 30 ft. Leaves always perfectly 

 glabrous. This species is extensively cultivated for the long tough rods 

 which it produces when cut down, which are in frequent use for wicker- 

 work, hoops, &c. " S. triandra is one of the most valuable osiers. It is 

 cultivated for white basketwork, producing rods 8 ft. or 9 ft. long, tough 

 and pliant, even when stripped of their bark, and very durable. They are 

 cut down every year." (Smith in Eng. Fl.) There are plants in the Gold- 

 worth arboretum, at Flitwick House, at Henfield, and at Woburn Abbey. 

 Varieties. Several varieties, if not distinct species, are comprehended under 

 the name of S. triandra. " Of these, I venture to separate one as a species,
