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

Stamens 2 toa flower. Ovaries silky. Leaves between obovate and lanceo- 
late, glabrous, or nearly so; dark green on the upper surface, very glaucous

Koch has included under one species, to which he has applied the name 
S.arbascula Wahlenberg, several of-the species or kinds of this group. 
The constituents of this species are as follows : — As synonymes, S. arbas- 
cula Wahlenb. Fl. Lapp., No. 476., Fl. Suec., No. 1122.; S. arbdscula 
a Lin. Suec., No. 386., Sp. Pl., p. 1445., not of Smith, nor Vahl, nor 
Jacq. — As varieties, Lin. Fl. Lapp., t. 8. f. c.; S. phylicifolia Smith FI.

Smith Fl. Brit.; S. petrze‘a Anderson; S. Crowedna Smith, Dr. Lindley, 
in his Synopsis of the British Flora, has added to these the following kinds, 
elucidated by Borrer in Eng. Bot. Suppl., and treated as species below: 
— S. laxiflora Borrer; S. phillyreifolia Borrer; S. propinqua Borrer; 8S. 
Weigelidna Borrer; S. nitens Smith; S. tendiior Borrer. In the part of the 
prefatory matter of the group Nigricantes relating to S. phylicifolia Koch, 
some information on the above S. arbascula Koch is incidentally given. 
% 129, S. reENU‘IoR Borrer. The narrower-leaved intermediate Willow. 
Identification. Borrer in Eng. Bot. Suppl., t. 2650.; Hook. Br. F1, ed. 2., p. 425. 
Synonymes. Specimens were communicated to Smith, who appears to have united this kind with 
the S. /adrina’Smith, the S. bicolor Smith Bag. Bot., t. 1806. (Borrer.) , 
The Sexes, The-female is described and figured in Eng. Bot. Suppl.; the male is not known. 
Engraving. Eng. Bot. Suppl., t. 2650. 
Spec. Char., §c. 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 the 
ian Bracteas (scales) acute, longer than the silky stalk of the capsule. 
Style longer than the ovate stigmas (Biever) Found by the river Lochy, 
near Killin, in Breadalbane. The specimens figured were taken from a 
plant brought thence in 1810. An upright shrub, 15 ft. or more high. 
Branches loosely spreading. Disk of leaves about 2in. long, when first 
unfolded, 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, earlier 
than the leaves, about the beginning of May. Catkin about 1 in. long, 
while the flowers are in blossom; eventually about 2in. Mr. Borrer has 
indicated its affinity as follows: — Very near S, /aGrina Smith; and, like 
it, intermediate between the common sallows and the glabrous bright- 
leaved affinities of S. phylicifolia; resembling some of the former more 
nearly in general habit and in the shape of the leaves; the latter, in the 
deciduous nature of the pubescence, and in the glandulose stipules. S. 
nigricans angustifolia Seringe Saules de la Suisse, No. 22.: it is very similar 
to S. tentiior Borrer, There are plants at Henfield, and in the Goldworth 
Arboretum.
