SALIX.] SALICINE^. 371 



work, but is not indigenous. Andersson supposes it to be a smooth-fruited 

 hybrid between triandra or alba, and wminalis. S. Trevira'ni, Spr., is 

 another hybrid with viminalis, found in Staffordshire. 



2. S. pentan'dra, L. ; leaves elliptic or ovate- or obovate-lanceola'e 

 acuminate glandular-serrulate viscid shining paler beneath, disk of male 

 and female flowers 2-glandular, stamens 5 (4-12). Bay-leaved Willow. 

 River-banks and wet places, from N. Wales, "Worcester, and York to Argyll 



and Banff; planted S. of this ; ascends to 1,300 ft. in Northumbd. ; rare in 

 Ireland ; fl. May-June. A glabrous shrub, 6-8 ft., or tree, 20 ft. ; dark 

 brown. Leaves 1-4 in., fragrant, reticulate beneath ; stipules ovate oblong 

 or 0. Catkins, male 1-2 in., erect then pendulous, scales oblong ; female 

 shorter. Capsule glabrous ; style short. DISTRIB. Europe (Arctic), excl. 

 Greece and Turkey, W. and N. Asia. The latest-flowering willow. S. cus- 

 pida'ta, Schultz (Meyeria'na, Willd.), found in Shropshire, is probably a 

 hybrid with frag'ilis. 



** Stamens 2, rarely more, free. Petiole glandular or not at the top. 



3. S. frag'ilis, L. ; leaves lanceolate long-acuminate glabrous glandular- 

 serrate pale or glaucous beneath, young hairy, stipules ^-cordate deciduous, 

 capsule pedicelled. Crack Willow, Withy. 



Marshy ground, from Ross sotithd. ; ascends to 1,300 ft. in Xorthumbd. ; 

 ? native in Scotland or Ireland ; Channel Islands ; fl. April-May. A tree, 

 80-90 ft., trunk sometimes 20 ft. in girth ; branches spreading obliquely 

 from the trunk ; twigs easily detached, smooth, polished. Leaves 3-6 in., 

 petiole often glandular at the top. Catkins usually spreading, stout, male 

 1-2 in., female slender, often longer ; scales linear-lanceolate ; disk 2-glandu- 

 lar. Stamens 2, rarely 3-5. Capsule glabrous ; style short. DISTRIB. 

 Europe, N. and "W. Asia ; in trod, in America. Andersson doubts this being 

 indigenous except in S.W. Asia. 



8. frag'ilis proper ; twigs yellow-brown, leaves elliptic-lanceolate. YAR. 

 S. decip'iens, Hoffm. ; twigs orange or crimson, leaves smaller, style 

 longer. 



S. Russellia'na, Sm. (Bedford Willow], a tree, 50 ft., trunk 12 ft. in girth, is 

 considered a hybrid between fragilis and alba, and referred to S. vir'idis, 

 Fries. Mr. Baker says it is a synonym of S. frag'ilis ; and that Fries' S 

 viridis is not a British plant. 



4. S. al'ba, L. ; leaves narrowly lanceolate long-acuminate silky on 

 both surfaces (except when old) glandular-serrate, stipules ovate-lanceolate 

 deciduous, capsule subsessile. White Willow. 



Marshy ground, always? planted, from Sutherland -sontbd. ; Ireland ; Channel 

 Islands ; fl. May. A large tree, 80 ft., trunk 20 ft. in girth ; bark fissured : 

 twigs not easily detached, silky. Leaves 2-4 in., glabrous when old, petiole 

 eglandular. Catkins slender, lax, erect, scales linear. Capsule glabrous, 

 style very short. DISTRIB. Europe, N. Africa, N. and W. Asia, N.W. 

 India. Timber most useful for carpentry and fuel ; bark for tanning. 



S. al'ba proper ; twigs olive, old leaves silky on both surfaces. YAR. S. caru'lea, 

 Sm. ; twigs olive, old leaves glabrous glaucous beneath. YAR. S. wtelli'xa
