SALIX 
57 
Common throughout the British Islands wherever the putative parents grow together. 
Recorded for Scandinavia, Denmark, Germany, Belgium, France, central Europe, Russia ; and doubtless as 
widespread as the putative parents.

Exsiccata : — Herb. Kew. (“a beautiful Alpine willow found on Ben Challum, Perthshire, 1876, by J. Sadler” 
is referred by the Rev. E. F. Linton to this hybrid); E. F. et W. R. Linton, 91 ; herb. Marshall, 2957, 2958. 
Dwarf undershrub. Branches slender, divaricate. Petioles slender, about a third as long as 
the laminae. Laminae more or less suborbicular, rounded to subcordate at the base, glandular, 
denticulate, about 1*5 to 2^5 long as a rule. Pistillate catkins lateral, on short leafy peduncles, 
small, about o - 5 — 1*5 cm. long. Style thick, rather long. Stigmas bifid. Capsules stalked, hairy. 
Staminate plants are unknown. 
Scotland — Perthshire. Not recorded for any other country.

Exsiccata: — E. F. et W. R. Linton, 52. 
A single plant — a shrub, nearly 2 m. high — of the above rather doubtful hybrid was described by White from specimens 
collected in Dumfriesshire. Linton’s no. 52 is from the same locality. Not recorded for any other country.

Undershrub, up to about 2 m. high when well grown, though usually more dwarf and less 
than 1 m. high. Stem creeping. Young branches and buds glabrescent. Stipules often persistent, 
serrate. Petioles short. Laminae elliptical, lanceolate, or oboval-oblong, variable in size, somewhat 
rugose. Catkins subsessile, rather dense, rather small, appearing a little before the leaves ; April 
and May. Bracts very hairy. Filaments pubescent towards the base. Ovaries pubescent. Style 
rather long. Stigmas emarginate. Capsules pubescent, stalked. 
The local distribution of the plants referred to this parentage points strongly to their probable hybrid origin ; for 
example, White (1890b) states that they are widely distributed in Perthshire and “of almost certain occurrence where the 
parents grow in proximity.” 
Max Wichura (op. cit. (1854)) asserts that he crossed a staminate plant of “ S. ambigua Ehrhart” with a pistillate one, 
and that the offspring resembled the parents 1 . However, Wichura does not appear to have allowed the offspring of this 
cross to grow to maturity, so that there was no chance of really establishing the conclusion that “ S. ambigua Ehrhart ” 
really breeds true. In fact, this conclusion is unlikely ; and it is desirable that the experiment should be repeated, using 
all Wichura’s preliminary precautions, but allowing the offspring to grow to the adult stage. 
Widespread, but rather local ; from Cornwall and Kent to Zetland ; Ireland — co. Cork and co. Galway, and 
doubtless elsewhere.
