SALIX 
Cambr. Brit. FI. ii. Plate 40. ( a ) Shoot with staminate catkins. ( b ) Shoot with pistillate catkins. 
(, c ) Barren shoot. ( d ) Staminate flowers (enlarged). ( e ) Pistillate flowers (enlarged). Drawn from specimens 
sent by the Rev. E. F. Linton, and produced by him by crossing S. lapponum and S', repens. 
Undershrub. Young branches pubescent, ultimately glabrous. Laminae elliptical, entire, sub- 
revolute, acute, pubescent to hairy. Catkins dense-flowered. Bracts broadly ovate, hairy. Styles 
rather long. Capsules sessile, hairy. 
Exsiccata : — E. F. et W. R. Linton, 87 (artificial hybrid); herb. Marshall, 709, 2963 B. 
Perthshire. 
Sweden, Germany, Austria, and Russia. 
•S. lapporntm x reticulata Giirke Plant. Europ. ii, 38 (1897); A. et G. Camus Classif. Saul, ii, 252 
(1905); x S. sibyllina White in Journ. Linn. Soc. xxvii, 446 (1890). 
Some leaf-specimens in Herb. Univ. Edinb. are regarded by White as having the above parentage. The specimens were 
gathered by Greville, Forfarshire, in 1824. Not recorded for any other country. 
[tSALIX HELVETICA] 
fSalix helvetica Villars Hist. PI. Dauph. iii, 783 (1789); A. et G. Camus Classif. Saul. 1 5 1 (1904); 
S. lapponum var. helvetica Andersson in DC. Prodr. xvi, pt. ii, 277 (1868); S. Iapp 07 ium subsp. helvetica v. Seemen 
in Ascherson und Graebner Syn. iv, 186 (1909) excl. syn. Reichenbach ; Rouy FI. France xii, 201 (1910); 
excluding syn. S. arenaria Smith and S. glauca Smith and their equivalents, and excluding references to 
Reichenbach Exsicc. 1628 et 2520. 
Exsiccata: — A. et J. Kerner 5, 89; herb. Smith, as 5 . glauca. 
Differs from S. lapponum in the following characters : — Laminae darker green and glabrous 
above, snowy white below. Catkins on longer peduncles which are leafy towards the base, and more 
slender. Ovaries snowy white with very dense hairs, almost as in 3 ". glauca L. 1 
White (op. cit. p. 428) points out that a specimen in Herb. Univ. Edinb. labelled by Winch “ Salix glauca Ben 
Lawers,” Perthshire, is S', helvetica Villars ; and the Rev. E. F. Linton, as is seen by a note on the same sheet, subscribes to 
this determination. The specimen undoubtedly agrees with the original description of S. helvetica. Winch’s specimen also 
agrees with specimens in Smith’s herbarium named by Smith S. glauca. There is an identical plant in herb. Forster (in 
Herb. Mus. Brit.) by Winch “from Scotland,” and another from Borrer in Herb. Univ.' Cantab, labelled by Babington 
“S’, glauca Smith! (Borrer); Mr Borrer’s garden, 1844.” 
However, these plants — V. glauca Smith herb. — are not, in our opinion, .S’. glauca Smith Eng. Bot. t. 1810, which we 
regard as the same as S. arenaria Smith Eng. Bot. t. 1809, both of which, along with S. stuartiana Smith Eng. Bot. 
t. 2586, we place under 5 . lapponum. 
We believe that the description of .S. glauca Smith Eng. FI. iv, 201 (1828) refers to S. helvetica-, but the initial 
diagnosis is simply repeated from S. glauca of his English Botany. 
With regard to Winch’s record of S. helvetica (sub nom. S. glauca) from Ben Lawers, White remarks that “it is 
desirable that it should be rediscovered.” Perhaps White suspected that there had been some mixing or planting of 
specimens, a view we are inclined to adopt. Cf. 5 . hastata (see below) and S. rosmarinifolia (page 48). 
In the Alps of France, Switzerland (ascending to about 2600 m.), Austria, and Italy. Recorded also for 
Scandinavia, but we have seen no specimens. 
[*SALIX HASTATA]

und Graebner Syn. iv, 152 (1909); Rouy FI. France xii, 212 (1910); S', malifolia Smith FI. Brit. 1053 ( 1 804) ! ; 
Eng. FI. iv, 180 (1828). 
leones: — Svensk Bot. t. 719; Smith Eng. Bot. t. 1617, as S. malifolia ; Forbes Sal. Woburn, t. 35, t. 36, 
as S. malifolia ; FI. Dan. t. 1238; Reichenbach Icon. t. 570, fig. 2013 [1213]; Hartig Forst. Culturffl. t. 111

Exsiccata: — Billot, 3899, as S. jayetiana\ Fries, iii, 53; A. et J. Kerner, 41, 42; Reichenbach, 956; 
Leefe, ii, 36, as S. hastata var. malifolia. 
Undershrub, 1 — 2 m. high. Stipules often very large (up to 2^5 cm.) giving the leaves a hastate 
appearance. Petioles short, stout. Laminae ovate or elliptical, acute, glabrous on both surfaces, 
about 4 — 6 cm. long and 2^5 broad. Catkins on leafy peduncles, appearing with the leaves; May and 
June. Styles rather long. Stigmas about as long as the style. Capsule stalked, glabrous; June 
and early July. 
1 S. glauca L. Sp. PI. 1019 (1753) is not known to be a British plant. Cf. Billot, 1961 ; Fellman, 216; Fries, iii, 52; A. et 
J. Kerner, 77, 78 ; Reichenbach, 1628, 2520. Has leaves as in S. lapponum , stout catkins, and capsules white with very dense hairs. 
It should be searched for in Scotland. S. glauca x lapponum occurs in Scandinavia, and A. glauca x helvetica in Switzerland.
