SALIX 
few-flowered, about 5 — 10 mm. long, on peduncles rather shorter, subcontemporaneous, June. Bracts 
broadly oval or oboval, ciliate or glabrous, yellowish-green, margin often darker. Nectaries yellow. 
Style short, distinct. Stigmas large, yellowish or tinged with purple. Capsules usually more or less 
pedicelled, narrowly ovate or oblong; July. 
The figure in Sal. Woburn, t. 62, purporting to be of this species, is perhaps a hybrid. 
The unusually low altitudes to which this and some other Arctic-Alpine willows descend in the British Isles sometimes 
cause a strange juxtaposition of species. It is doubtless due to this fact that there are in this country a number of endemic 
natural hybrids of the species of this genus. 
Among humus on mountains, on siliceous soils ; Brecknockshire, Carmarthenshire, and Car- 
narvonshire ; central and northern Pennines, and northwards locally to Zetland ; south-western, 
western, and northern Ireland; ascending to about 1300m. on Ben Nevis, and descending to 
about 260 m. in co. Donegal and 90 m. in Sutherlandshire. 
Northern and Arctic Europe (including the Faeroes and Iceland), Asia, and America; mountains 
of western, central, and southern Europe ; Greenland, Labrador and U.S.A., southwards to Mt. 
Katahdin, Me., and Mt. Washington, N. H.

Dwarf undershrub. Branches prostrate, glabrous at maturity. Buds large, scales subpersistent 
as in N. reticulata. Petiole about one-third to one-half as long as the lamina. Laminae suborbicular, 
crenulate, prominently reticulated on both surfaces, subglaucous underneath. Catkins resembling those 
of S. herbacea , but larger (about cr8 cm. long), peduncled. 
Enander ( Sched . Sal. Scand. i, 2 (1911)) takes a different view of the hybrids of S. herbacea and S. reticulata from 
other authorities. His opinions are supported by excellent specimens which may be consulted in Herb. Kew. 
Perthshire, Forfarshire. 
Also recorded for northern Scandinavia.

Series of Vetrix 
Series vi. Lanatae (p. 29). Undershrubs of Arctic distribution. Young branches thick, hairy. 
Laminae broadly elliptical to suborbicular, very hairy with long and more or less silky hairs at least 
when young. Catkins terminal or lateral, large, stout, sessile to shortly peduncled, peduncles not 
leafy. Bracts discolorous with long hairs. Anthers golden yellow. Style long, slender. Stigmas 
short, rather stout, more or less bifid or entire. Capsules shortly stalked, rather narrow, glabrous. 
Series vii. Myrsinites (p. 31). Undershrubs of Arctic- Alpine distribution. Laminae ovate 
or lanceolate-ovate, glabrous and shining at maturity, strongly reticulated on both sides, turning 
blackish on drying. Catkins lateral, on short peduncles leafy or leafy at the base, appearing with 
the leaves. Bracts discolorous, with long hairs. Nectaries 1, oblong-linear, purplish. Anthers 
reddish before dehiscence. Styles usually rather long and slender, purplish. Stigmas purplish, 
shorter than the style, more or less bifid. Catkins usually slightly hairy, shortly stalked. Capsules 
shortly stalked. 
Series viii. Glaucae (p. 33). Undershrubs of Arctic- Alpine distribution. Laminae elliptical 
or oblong-elliptical, entire. Catkins lateral, on short peduncles, broadly elliptical or cylindrical. 
Style long at maturity. Stigmas rather long, often more or less bifid. Capsules subsessile or shortly 
stalked, hairy.
