WAYSIDE AND WOODLAND TREES. 
The Lapland Willow {Salix lapponuni) is of a similar propor- 
tion to the last-named, sometimes erect, sometimes trailing. 
Its leaves are more elliptic in shape, covered above with silky 
hairs and below with cottony filaments. In lanata the raised 
veins form a network pattern ; in lapponum they are straight. 
The stipules at the base of the long foot-stalk are small or 
altogether wanting. Like the preceding species, it is restricted 
to Scotch Alpine rocks, at elevations between 2000 and 2700 
feet. 
The Whortle-leaved Willow (^Salix myrsinites) is a small, wiry, 
creeping, or half-erect shrub, six inches to a foot high, with 
toothed, dark glossy leaves, an inch or less in length, whose 
net-veining shows on both sides. It is restricted to the Alpine 
parts of mid-Scotland, from 1000 to 2700 feet. 
The Small Tree-Willow {Salix arbuscula) is a small shrub, 
whose stem creeps along the ground and roots as it goes, send- 
ing up more or less erect branches a foot or two high. The downy 
twigs are first yellow, then reddish-brown. The small leaves 
vary from egg-shaped to lance-shaped, and are shining above 
and glaucous beneath ; toothed. In the Highlands of Aberdeen, 
Argyll, Dumfries, Forfar, and Perth, between 1000 and 2400 
feet. 
The Least Willow {Salix herbaced) is not so restricted in its 
range, for it is found in all parts of the United Kingdom where 
there are heights sufficiently Alpine (2000 to 4300 feet) for its 
tastes. It is only an inch or two high, and has consequently the 
distinction of being the smallest British shrub. It is not so 
herbaceous as it seems, or as its name implies, for its shrubby 
stem and branches creep along underground, sending up only 
short, scantly leaved twigs. The curled, roundish leaves do not 
exceed half an inch in length ; they are net-veined, toothed, 
and shining. The catkins appear after the leaves. 
The Net-leaved Willow {Salix reticulata) is another of the 
Scotch Alpines. It is similar in habit to the last-named, but
