SALIX 
39 
The British plants are referable to S. hastata var. vegeta Andersson Monogr. Sal. 172 (1867) (= var. malifolia Giirke 
Plant. Eur. ii, 22 (1897)). 
Like A. rosmarinifolia, this species was figured in Eng. Bot. (as S. malifolia ) ; but the evidence that it was British was 
then slight (see Smith Eng. FI. loc. cit.). Later, it was recorded from the Sands of Barrie, Forfarshire, by Drummond (see 
Hooker, Brit. FI. 433 (1830)); and there is a specimen by him from this locality in Herb. Mus. Brit. The plant has also 
been recorded from Middlesex (Woods, Bot. Guide , 413 (1805)). However, there is no evidence to show that S. hastata 
has ever occurred in this country as an indigenous plant.

Exsiccata : — Billot, 1962 ; Fries, vi, 61 ; A. et J. Kerner ( H.S.A. ), 33 ; Leefe ii, 47 ; E. F. et W. R. Linton, 22. 
Dwarf shrub, up to about 1 m. high. Branches erect, or ascending, or procumbent, or prostrate, 
short, sometimes rooting ; young ones glabrous in summer, smooth, somewhat shining. Stipules 
usually caducous, or small. Petioles short (2 — 4 mm.). Laminae broadly or narrowly oblong- 
elliptical to ovate, cuneate to broad at the base, margin glandular- 
denticulate to subentire, acute, with numerous white dots, somewhat 
shiny above, subglaucous underneath, turning blackish on drying. 
Catkins small, rarely more than about 2 cm. long, cylindrical, appearing 
with the leaves ; May. Bracts hairy, reddish-brown towards the summit, 
often not longer than half the ovary. Nectary comparatively large, 
yellowish. Staminate catkins subsessile, leafy at the base, rarely more 
than 1 '5 cm. long and often shorter. Filaments glabrous. Anthers 
reddish-yellow before dehiscence. Pistillate catkins on leafy peduncles 
which are sometimes as long as the catkins, longer than the stami- 
nate ones, elongating up to about 3 cm. in fruit. Ovaries pubescent. 
Style distinct, rather slender, usually comparatively long at maturity. 
Stigmas more or less bifid, yellowish or more or less tinged with pink. 
Capsules subsessile or on stalks shorter than the nectaries, more or less 
hairy ; June. 
The British forms are referable to var . foetida Koch Syn. 658 (1837) (= S. vacciniifolia 
Smith loc. cit.) and to var. prunifolia Koch loc. cit. (= S. prunifolia Smith loc. cit. and 
A. venulosa Smith loc. cit. and A. carinata Smith loc. cit.): the var. waldsteiniana Koch loc. cit. (= S. waldsteiniana Willdenow 
Sp. PI. iv, 679 (1805)) does not appear to be represented among the known British forms.
