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

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

 another hybrid with vitninalis, 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 llowers 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 (Meyevia'na, Willd.), found in Shropshire, is probably a 

 hybrid with frag' His. 



** Stamens 2, rarely move, 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 J-cordate deciduous, 

 capsule pedicelled. Crack Willow, Withy. 



Marshy ground, from Ross southd. ; ascends to 1,300 ft. in Northumbd. ; 

 ? 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, of ten longer ; scales linear-lanceolate; disk 2-glandu- 

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

 Europe, N. and W. Asia ; introd. in America. — Andersson doubts this being 

 indigenous except in S.W. Asia. 



. frag'ilis proper ; twigs yellow-brown, leaves elliptic-lanceolate. — Var. 

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

 longer. 



% 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 

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

 leciduous, capsule subsessile. White Willow. 



[arshy ground, always? planted, from Sutherland southd. ; 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. 

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

 Sm. ; twigs olive, old leaves glabrous glaucous beneath. — Var. S. vitelli'na
