on short;, leafy shoots or peduncles. Capsules nearly sessile, about 2 lines 

 long, more or less hairy. 



In the mountains of northern and Arctic Europe and Asia, and at 

 considerable elevations in the Alps and Pyrenees. In Britain, only in 

 the Scotch Highlands, and in the mountains of Sligo in Ireland. Fl. 

 early summer. Under the name of $. arbuscula the British Floras 

 include the plants figured in Eng. Bot. t. 1361, 1362, 1363, and 2341, 

 which appear to be either varieties of the whortle W., of rather larger 

 growth, with short peduncles to the catkins, and the leaves rather 

 glaucous underneath, or perhaps in some instances small-leaved varie- 

 ties of the tea-leaved IV., showing in their more toothed leaves and 

 more leafy peduncles an approach to the whortle W, 



14. Reticulate Willow. Salix reticulata, Linn. (Fig. 923.) 

 (Eng. Bot. t. 1908.) 



A prostrate, much branched shrub, 

 often spreading to a considerable extent, 

 but not rising above 5 or 6 inches from 

 the ground; the branches glabrous or 

 hairy when young. Leaves obovate or 

 orbicular, quite entire, f to 1 inch long 

 and broad, green, glabrous, and much 

 wrinkled above, white underneath. Cat- 

 kins on rather long, leafless peduncles, 

 at the ends of short branches, opposite j^g. 923. 



to the last leaf ; both males and females 



cylindrical, | to 1 inch long, shortly downy but not silky-hairy. Cap- 

 sules cottony, about 1\ lines long. 



In the mountains of northern and Arctic Europe, Asia, and America, 

 and at considerable elevations in the great mountain-ranges of central 

 Europe and Russian Asia. In Britain, probably confined to the Scotch 

 Highlands. Fl. summer. 



15. Dwarf Willow. Salix herbaeea, Linn. (Fig. 924.) 



(Eng. Bot. t. 1907.) 



The smallest of British shrubs, the half-underground stems creeping 

 and rooting sometimes to a considerable extent, the branches seldom 

 rising above 2 inches from the ground. Leaves obovate or orbicular, 

 about half an inch long, finely crenated, green, glabrous, and veined 

 like those of the whortle W., or sometimes slightly silky-hairy when 

 young. Catkins very small, ovoid, and few-flowered, on very short,
