SALIX.] SALICINE^!. 337 



A'. Ttxfsellia'na, Sm. (Bedford Willow), a tree 50ft., trunk 12ft. in girth, is 

 considered a hybrid between fragilis and alba, and referred to S. viridit, 

 Fries. Mr. Baker, however, regards it as not even a var. of S. fragilis ; and 

 considers Fries' S. viridis to be different, and not a British plant. 



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

 sides (except when old) glandular-serrate, stipules ovate-lanceolate deci- 

 duous, capsule subsessile. White Willow. 



Marshy ground, from Sutherland southwards; a doubtful native of Ireland ; fl. 

 May. A large tree, 80 ft., trunk 20 ft. in girth; bark fissured; twigs not 

 fragile at the forks, silky. Leaves 2-4 in., glabrous when old, petiole 

 eglandular. Catkins appearing with the leaves, slender, lax, erect, scales 

 linear. Filaments hairy below the middle. Capsule glabrous, style very 

 short. DISTEIB. Europe, N. Africa, Siberia, W. Asia to N.W. India. 

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



VAR. 1, al'ba proper ; twigs olive, old leaves silky on both surfaces. VAR. 2, 

 cceru'lta, Sm. (sp.) ; twigs olive, old leaves glabrous, glaucous beneath. VAR. 

 3, vitelli'na, L. (sp. ) ; twigs yellow or reddish, old leaves glabrous above, 

 scales of catkins longer. Golden Willow. 

 SECTION 2. Catkins on leafy or bracteate peduncles ; scales persistent, 



discoloured at the tip (except S. rcticulata). Stamens 2, filaments glabrous 



free. Disk 1 -glandular. Capsule tomentose or silky, rarely glabrous. 

 * Capsule with a slender pedicel ; style very short or 0. 



5. S. Capre'a, L. ; leaves elliptic or oblong-obovate or -lanceolate acute 

 or acuminate crenate reticulate on both surfaces tomentose below, stipules 

 4-renifonn, catkins silky, male ovoid-oblong, female elongate at length 

 nodding, scales pilose, tip black. Common Sallow, Goat-willow. 

 Copses, pastures, &c., by streams, from Inverness southwards; ascending to 



2,000 ft. in the Highlands ; fl. April-May. A silvery tree or large shrub. 

 Leaves 2-4 in., dark green above, cuspidate, margins narrowly recurved. 

 Catkins short, preceding the leaves, sessile, bracteate ; male 1 in., very 

 stout, female lengthening to 3 in. Filaments glabrous. Capsule J in., 

 silky ; pedicel very slender. DISTRIB. Europe, N. Asia, W. Asia to the 

 Himalaya. The earliest flowering British willow. The twigs with catkins 

 gathered at Easter, are called Palm-branches. Andersson points out the 

 impossibility of distinguishing this from S. cinerea, L. 



Sub-sp. CAPRE'A proper; buds and twigs glabrous or puberulous, leaves 

 usually broad glabrous and dull green above. VAR. 1, leaves undulate 

 crenate-serrate, stipules long. VAR. 2, leaves almost entire, stipules 0. A 

 small bush, not uncommon in Highland gullies. 



Sub-sp. CINE'REA, L. (sp. ) ; buds and twigs tomentose, leaves smaller narrower 

 from elliptic-oblong to oblanceolate undulate at the margins pubescent 

 above, male catkins less stout opening later, anthers paler yellow, capsule 

 smaller (filaments pilose at the base, Syme).- VAR. 1, cinerea proper ; leaves 

 oblong-lanceolate glaucous, hairs beneath often red-brown, stipules large. 

 VAR. 2, aquatica, Sm. (sp.) ; leaves more obovate glaucous, hairs beneath 

 white, stipules large. VAR. 3, oleifo'lia, Sm. (sp.) ; leaves narrow rigid 

 glaucous, hairs beneath red-brown, stipules small. Andersson correctly 

 refers the S. cine'rea of Smith in Eng. Bot. (t. 1897) to this ; but also quotes 

 that plate and name under daphnoi'des, Vill., a very different plant. 



6. S. auri'ta, L. ; leaves obovate-oblong rarely oblanceolate crenate
