more in length, downy. Catkins from 2 in. to 3 in. long when matured.The branches are brittle, and apt to break when used for tying. There areplants at Woburn, Henfield, and Flitwick.

Group xviii. Bicolores Borrer.

Bushy Shrubs, with Leaves dark green above, and glaucous beneath.

Stamens 2 to a flower. Ovaries silky. Leaves between obovate and lanceo-late, glabrous, or nearly so; dark green on the upper surface, very glaucouson the under one. Plants twiggy bushes. (Hook. Br. FI., ed. 2., adapted.)Koch has included under one species, to which he has applied the nameS. arbuscula Wahlenberg, several of the species or kinds of this group.The constituents of this species are as follows: — As synonymes, S. arbus-cula Wahlenb. FI. Lapp., No. 476., FI. Suec., No. 1122.; S. arbusculaa Lin. Suec., No. 386., Sp. PL, p. 1445., not of Smith, nor Vahl, norJacq. — As varieties, Lin. FI. Lapp., t. 8. f. c.; S. phylicifolia Smith FI.Brit .; S. radicans Smith FI. Brit.; S. tetrapla Walker; S. humilis Willd.Berl. Baumz.; S. Dicksoniena Smith ; S. Weigeliana Willd. Sp. PI., p. 678. ;S. /aurina Smith-, S. majalis Wahlenb. FI. Lapp., p. 270.; S. tenuifoliaSmith FI. Brit.; S. petras'a Anderson; S. Crow edna Smith. Dr. Lindley,in his Synopsis of the British Flora, has added to these the following kinds,elucidated by Borrer in Eng. Bot. Snppl., and treated as species below:— S. laxifldra Borrer; S. phillyreifolia Borrer; S. propinqua Borrer; S.Weigel iana Borrer; S. nitens Smith-, S. tenuior Borrer. In the part of theprefatory matter of the group Nigricantes relating to S. phylicifolia Koch,some information on the above S. arbuscula Koch is incidentally given.

at 129. S. tenu'ior Borrer. The narrower-leaved intermediate Willow.

Identification. Borrer in Eng, Bot. Suppl., t. 2650. j Hook. Br. Ft, ed. 2., p. 425.

Synonymes. Specimens were communicated to Smith, who appears to have united this kind withthe S. fafaina Smith, the S. bicolor Smith Eng. Bot., t 1806. {Borrer.)

The Sexes. Thejfemale is described and figured in Eng. Bot. Suppl. j the male is not known.

Spec. Char., fyc. Disk of leaf obovate-lanceolate, acute, obsoletely crenate,flat; glabrous on both surfaces, glaucous on the under one. Petiole slender.Stipules acute, glandulose. Catkin slender. Flowers laxly disposed in thecatkin. Bracteas (scales) acute, longer than the silky stalk of the capsule.Style longer than the ovate stigma3 (Borrer.) Found by the river Lochy,near Klllin, in Breadalbane. The specimens figured were taken from aplant brought thence in 1810. An upright shrub, 15 ft. or more high.Branches loosely spreading. Disk of leaves about 2 in. long, when firstunfolded, sprinkled with appressed hairs on both surfaces, but soon becom-ing glabrous except the midrib; upper surface dark green and shining.Petiole long, pale, downy. The flowers appear, with Mr. Borrer, earlierthan the leaves, about the beginning of May. Catkin about 1 in. long,while the flowers are in blossom; eventually about 2 in. Mr. Borrer hasindicated its affinity as follows: — Very near S. laurina Smith; and, likeit, intermediate between the common sallows and the glabrous bright-leaved affinities of S. johylicifolia; resembling some of the former morenearly in general habit and in the shape of the leaves; the latter, in thedeciduous nature of the pubescence, and in the glandulose stipules. S.nigricans angustifolia Seringe Saules de la Suisse, No. 22.: it is very similarto S. teniiior Borrer. There are plants at Henfield, and in the GoldworthArboretum.
