present time for the same purpose in Belgium ; and when imported is called 

 " Belgian red willow." It is occasionally planted for ornament, appearing in some 

 nursery catalogues under the name S. cardinalis.

 (Bot.) xxvii. 353 (1890). 



Salix fragilis, var. lalifolia, 1 Andersson, in De Candolle, Prod. xvi. 2, p. 209 (1868). 



A large tree, similar in bark and habit to S. fragilis. Young branchlets 

 slightly pubescent, glabrous in the second year. Leaves longer and broader than 

 those of S. fragilis, up to 6 in. long and if in. wide ; broadly lanceolate, with 

 a long acuminate often curved apex ; pubescent when young ; when mature, upper 

 surface dark green, shining, glabrous ; lower surface pale, glabrescent, or with scattered 

 appressed hairs ; margin coarsely glandular-serrate ; petiole \ in. long, often with 

 one to four glands at the junction with the blade. 



Staminate catkins, 2\ in. long ; flowers crowded on the densely pubescent 

 axis ; scale, shorter than the stamens, and covered with long white silky hairs ; 

 stamens usually two, rarely three, glabrous or pilose at the base ; glands two, 

 variable, entire or lobed. Pistillate flowers not seen. 



The above description is drawn up from an old tree 1 on the side of the lake 

 at Kew, which has been named S. triandra x fragilis? by Linton. It is identical 

 with some trees, which have been called " open-bark willow," by Carter, and is 

 perhaps not very rare in Britain. 



3. Salix viridis, Fries, Nov. PI. Snec. 283 (1828); Andersson, in De Candolle, 

 Prod. xvi. 2, p. 210 (1868); Buchanan White, in Journ. Linn. Soc. {Bot.) xxvii.

Salix excelsior, Host, Sal. 8, tt. 28, 29 (1828). 



Salix palustris, Host, Sal. 7, tt. 24, 25 (1828). 



Salix montana, Forbes, Sal. Woburn. 37, t. 19 (1829). 



Salix fragilis-alba, Wimmer, Denkschr. Schles. Ges. 156 (1853). 



A tree similar in size to the reported parents, S. alba and S. fragilis, with 

 spreading branches, and usually more or less pendulous branchlets. Young 

 branchlets variable, glabrous or pubescent. Leaves intermediate between these 

 two species, variable in size, shape, colour, and pubescence ; darker green, 

 less shining, more finely serrated, and less oblique at the apex than those of 

 5. fragilis ; longer and broader than those of S. alba, and soon becoming 

 glabrescent. 



Staminate catkins narrower and larger than in S. fragilis. Pistillate catkins 

 more slender than in that species ; ovary shortly but distinctly pedicellate ; capsules 

 intermediate in size between S. alba and S. fragilis. 



1 Specimens which were sent from Kew to Buchanan White in 1887 and 1888, and are now preserved in his herbarium 

 at Perth, show that this tree was then labelled S. fragilis, var. laiifolia, a name accepted by White. 



* 5. alopecuroides, Tausch, Ind. Hort. Canal. (1821), ex Andersson, in De Candolle, Prod. xvi. 2, p. 203 (1868); A. 

 Kerner, in Verh. Z. B. Ges. Wien, 69 (i860); Koch, Dendrologie, ii. pt. i. 516 (1872), is the name given to the hybrid 

 S. triandra x fragilis, which occurs on the continent. This, judging from Tausch's specimen, preserved in the Cambridge 

 Herbarium, is quite distinct from 5. speciosa, Host.
