which, and especially in those from the younger Jacquin preserved in the Smithian collection, the bracteal leaves are large and closely resemble those of the leafy twigs; and the scales of the catkin are naked, except a marginal fringe." (Borrer in Eng. Bot. Suppl., t. 2656.) The S. Wulfeniana of Willdenow appears to be a native of Carinthia, where it was found by Wulfen. It flowers from May to July, and was introduced in 1818.

S. árctica R. Br., in his List of the Plants collected in Ross's Voyage. Koch, in his Comm., p. 61., note, considers this species about intermediate between S. Jacquinii Host and S. reticulata L.; and he has described it. He states it to be a native of the most northern part of America, Hudson's Bay, Melville Island, &c. It is also described by Dr. Richardson, in App. to Franklin's First Journey, p. 752, 753. According to Dr. Lindley (Nat. Syst. of Bot.), it is the most northern woody plant that is known. Mr. Borrer considers it to be near S. cordifolia Pursh.

S. desertòrum Rich, and S. rostrata Rich. are mentioned by Dr. Richardson, in App. to Franklin's First Journey, as new species.

S. cinerascens Link MSS. (Willd. Sp. Pl., 4. p. 706.; Smith in Rees's Cyclo, No. 152.), the ashcoloured Portuguese willow, has the leaves oblong-obovate, pointed, and serrated; hoary with down beneath. Stipules large, lunate, and toothed. (Willd. and Smith.) A native of marshes in Portugal. This kind is supposed by Koch to be probably identical, or nearly so, with the S. grandifolia of Seringe; and it appears to belong to the group Cinèreæ.

S. grandifolia Seringe Sal. Helv., p. 20.; Koch Comm., p. 36.; S. stipulàris Ser. Sal. exsicc.; S. cinerascens Willd. Sp. Pl., 4. p. 706. This kind is supposed by Koch to be the same as S. cinerascens ; and it appears to resemble S. càprea.

S. divaricata Pall. Fl. Ross., 2. p. 80., Willd. Sp. Pl., 4. p. 675., Smith in Rees's Cyclo., No. 52. This species is a native of the alps of Dauria, where it grows among granite rocks, over which it spreads in a prostrate form. The stem is about as thick as the finger, very much divided, and forked from its origin, with short, rigid, depressed, yellowish brown branches. The leaves are crowded about the ends of the shoots; in some specimens lanceolate, and nearly entire; in others obovatelanceolate, coarsely serrated, the serratures somewhat wavy and obtuse : both sides are quite smooth. Pallas states that this kind resembles the S. phylicifolia of Linnæus. (Smith.)

S. hirsuta Thunb. Prod., 6., Fl. Cap., 1. p. 141; Willd. Sp. Pl., No. 695., Smith in Rees's Cyclo., No. 106. A tree 6 ft. high, a native of the Cape of Good Hope; with the leaves on the extreme shoots scarcely 1 in. long, and on very short footstalks, obovate, obtuse, with a point, and clothed on both sides with white hairs. (Thunb. and Smith.)

?S. pedicellata Desf. Atlant., 2. p. 362., Willd. Sp. Pl., 4. p. 706., Smith in Rees's Cyclo., No 133. The stalked Barbary Sallow. Leaves lanceolate, rugose, downy beneath. Capsules stalked, and glabrous. Nearly allied to S. càprea, but differing in the smoothness of the capsule. (Smith, adapted.)

S. integra Thunb. Fl. Jap., 24., Willd. Sp. Pl., 4. p. 686., Smith in Rees's Cyclo., No. 81. The entire-leaved Japan Willow. Leaves entire, smooth, linear oblong, obtuse. Gathered by Thunberg

in Japan. (Smith.)

S. japonica Thunb. Fl. Jap., 24.; Willd. Sp. Pl., 4. p. 668., Smith in Rees's Cyclo., No. 34. ; Rju, vulgo Aujaki, Kæmpfer Amon. Exot., 908. Leaves serrated, glabrous, lanceolate, glaucous beneath. Twigs pendulous. A middle-sized tree; a native of Japan.

S. mucronata Thunb. Prod., 6., Fl. Cap., 1. 140.; Willd. Sp. Pl., 4. p. 685.; Smith in Rees's Cyclo., No. 74. Leaves entire, smooth, oblong, pointed, and about 1 in. in length. Gathered, at the Cape of Good Hope, by Thunberg. (Smith.)

S. rhamnifolia Pall. Fl. Ross., 2. p. 84., Willd. Sp. Pl., 4. p. 53., Smith in Rees's Cyclo., No. 53.; S. pùmila, foliis oválibus, &c., Gmel. Sib., 1. t. 35. f. A. A procumbent shrub, a native of mountain bogs, and the stony banks of rivers, in Siberia. Leaves firm and rigid; about 14 in. long, and mostly tapering at the base. (Smith.)

S. Seringeana Gaudin in Seringe's Sal. Helv., p. 37., Koch Comm., p. 33.; S. lanceolata Ser. Sal. ersicc., No. 70. ; S. Kanderiana Ser. Sal exsicc., No. 42.; S. longifolia Schleich. Cat.

Spec. Char., &c. Leaves oblong-lanceolate, acuminate, crenulate; white on the under surface with white tomentum, and rugose with veins. Stipules ovate, acute. Catkins arched, sessile, slender, bracteated at the base with small leaves. Capsule ovate-lanceolate, tomentose, stalked; the stalk twice as long as the gland. Style elongated. Stigmas bifid. (Koch.) It grows wild by rivulets, in subalpine valleys of Switzerland and Tyrol. (Id.)

S. serótina Pall. Fl. Ross., 1. p. 2. 77., Itin., 3. 759. t. N. n., Smith in Rees's Cyclo., No. 83., and incidentally in Eng. Flora, 4. p. 228.; S. No. 19. Gmel. Sib., 1. 163.; S. càprea y Lin. Sp. Pl., 1448.; S. ægyptiaca Willd., so far as relates to the synonyme of Pallas; S. Gmeliniàna Willd. Sp. Pl., 4. p. 709.

Spec. Char., &c. Leaves elliptic-lanceolate, entire, often more than a span long; rather downy on the upper surface, silky on the under one, revolute in the bud. Stipules lanceolate. Catkins sessile, unattended by leaves, very hairy. Ovaries lanceolate, silky, stalked. (Smith.) Abundant in the sandy islands and shallows in the southern parts of the Wolga; not expanding its catkins or leaves till the beginning of June. In dry ground, it becomes a tree; but is otherwise shrubby, 6 ft. high; with brittle grey or yellowish twigs, glabrous, except when very young. It is distinguished from S. càprea, by its broad and serrated leaves, and ovate ovaries. (İď.)

To the names above given many others might be added, and in particular the greater number of those described in Host's Flora Austriaca, which we have preferred giving in a separate Appendix. See App. iv.

The plates, which form pages 1603. to 1650., contain figures of leaves, of the natural size, from the engravings of willows given in the Salictum Woburnense ; and against each leaf, or pair of leaves, we have placed the same number, and the same name, which are given in the Salictum. In App. ii., in p. 1631., will be found an alphabetical list of all these names, with references to the figures of leaves in our pages; and the same figures are also referred to, where the respective kinds are described, in the description of willows in British collections, contained in the pages between p. 1490. and p. 1595.
