S. INCANA, Schrank. HOARY WILLOW. 



(S. rosmarinifolia, Gouan (not of Limiirns).} 



A shrub of dense, very leafy habit, bushy, up to 8 or 12 ft. high, half as 

 much more in diameter ; rarely a small tree ; young shoots clothed with a 

 fine grey felt at first, becoming smooth later ; buds yellowish. Leaves 

 linear, tapered at both ends ; 2 to 5 ins. long, to fa in. wide ; made 

 narrower by the decurved margins ; dark green and smooth above, covered 

 with a blue- white felt beneath. Catkins erect, slender ; females i to i^ ins. 

 long ; males shorter, appearing with the young leaves in April and May ; 

 stamens two. 



Native of Europe and Asia Minor; introduced about 1820. It is one of 

 the prettiest and most effective of bush willows in foliage. Its leaves 

 resemble those of viminalis only they are not so coarse, or so glistening 

 beneath. Very desirable for the banks of ponds, etc. It is sometimes seen 

 under the name S. rosmarinifolia (q.v.}. 



S. LAN AT A, Linnceus. WOOLLY WILLOW. 



A low, sturdy bush, 2 to 3 ft. high; branchlets stout, furnished when young 

 with thick, soft, grey wool. Leaves silvery on both sides, with a rich coat of 

 silky hairs, especially at first ; oval to roundish or obovate, mostly abruptly 

 pointed at the apex and tapered at the base, but sometimes rounded or 

 heart-shaped ; I to 2^ ins. long, ^ to i^ ins. wide, nearly always entire ; 

 stalk \ to |- in. long ; stipules up to \ in. long, ovate, entire, prominently 

 veined. Catkins produced in May, often solitary at the end of the previous 

 season's growth, of a bright golden colour ; males i to 2 ins. long, \ in. 

 thick ; females up to 3 ins. long at the seeding stage. 



Native of high latitudes in JEurope and Asia ; found in Scotland in the 

 East Grampians. It is one of the handsomest of dwarf willows, especially in 

 spring, when the silver foliage and golden catkins are in admirable contrast. 

 It is allied to S. Lapponum, but has broader, rounder leaves, whilst the 

 catkins of S. Lapponum are silky white. 



S. SADLERI, Syme, is a very distinct form of lanata, or a hybrid between 

 that species and perhaps herbacea. It was discovered in Aberdeenshire, in 

 August 1874, by Mr John Sadler, then of the Edinburgh Botanic Gardens. 



S. LAPPONUM, Linnaus. LAPLAND WILLOW. 



A shrub of spreading, much-branched habit, 2 to 4 ft. high ; young shoots 

 dark brown, more or less downy. Leaves oval or somewhat obovate, 

 occasionally lanceolate, tapered at both ends or sometimes rounded -at the 

 base, not toothed except rarely ; i to 3 ins. long, ^ to i ins. wide ; cottony 

 above, becoming nearly or quite smooth with age ; lower surface permanently 

 woolly beneath, silvery white at first, ultimately grey; stalk \ to in. long ; 

 stipules inconspicuous or absent. Catkins produced on the naked shoots in 

 April and May, very silky ; males about i in. long, stalkless ; females longer, 

 shortly stalked. 



Native of the high latitudes and altitudes of Europe and Siberia ; not 

 uncommon on the Perthshire mountains, and has also been found on 

 Helvellyn. It varies much in width of leaf, some forms found in Scotland 

 being almost linear. 



S. LASIANDRA, Bentham. 



This fine willow belongs to the same group as S. pentandra, our native 

 bay willow, and S. lucida, and is, according to Sargent, often a tree 60 ft.
