Shrub or dwarf shrub, a great number of forms occurring, some of which have been 
named by continental botanists. “In its best form,” says White {Joe. cit.), it “combines the 
characteristics of its parents, deriving from myrsinites the rigidity, glossiness, and in part the 
venation of the leaves, the often erect leafy-peduncled catkins, and the structure and colour of 
the style and stigmas, from nigricans the somewhat tomentose twigs and leaves, the greater 
thinness of the latter, and their greater tendency to become black in drying, the often longer 
petioles, and the often longer pedicels of the catkins.” Other forms pass imperceptibly into 
S. myrsinites, and still others into S. nigricans. 
Grows with the putative parents, among which it is not rare. Recorded for Perthshire, Forfarshire, and 
Aberdeenshire.

Wimmer {Sal. Eur. 35 (1866)) suggests that S. lapponum is closely allied to S. viminalis\ but we think it more reasonable 
to suppose that the resemblances of the two species are due to convergent development. The late Dr von Seemen {op. cit.) 
placed S. lapponum in the series Viminales and S. glauca in a far-removed series Sericeae ; but it appears to us that both 
species are better placed among the other Arctic-Alpine undershrubs than with lowland osiers. S. glauca has not been 
discovered in the British Isles (cf. page 38).

Species and chief hybrid of Glaucae 
10. S. lapponum (p. 34). Laminae elliptical or oblong-elliptical, about 2 '5 — 3^5 cm. long 
and ro — 1*5 broad, more or less covered with long hairs, especially underneath. Catkins stout, 
dense-flowered. Capsules very hairy. 
«S. herbacea x lapponttm (p. 35 )- Laminae broadly oval to ovate, up to about 3 cm. long and 
1*5 broad, with silky hairs when young. Catkins usually much more slender and more lax than in S. lapponum. 
[S. helvetica (p. 38). Laminae dark green above, snowy white below. Capsules with snowy white and 
dense hairs.] 
[S. hastata (p. 38). Stipules often very large, giving the leaves a hastate appearance. Laminae ovate 
or elliptical, glabrous. Catkins on leafy peduncles. Capsules glabrous.]
