216 ENGLISH BOTANY. 
Var. y, amygdalina. 
Prats MCCCXV. 
S. amygdalina, Linn. Sm. Eng. Bot. ed. i. No. 1936, and Engl. Fl. Vol. IV. p. 169. 
Hook, Brit. Fl. p. 357. 
Young twigs deeply furrowed. Leaves short, ovate-lanceolate, 
rounded at the base. Stipules larger than in Var. a. Leaves 
glaucous beneath. 
By the sides of streams and in wet woods and osier grounds. 
Common. Generally distributed in England. Rather rare in Scot- 
land, and absent from the north. Not unfrequent in Ireland, but 
often planted. Mr. Carroll considers it indigenous in Cork. 
England, Scotland, Ireland. Tree or shrub. Late Spring, Early 
Summer, sometimes again in Autumn. 
Usually a small tree or shrub, rarely, even when left to itself, 
attaining a height of 20 to 30 feet, and var. @ rarely more than 12 
feet. Bark on the trunk splitting off in sheets as in the plane-tree. 
Young branches brownish, breaking off readily at their origin. Leaves 
variable in shape and size, but usually 2 to 4 inches long when full 
grown, on short petioles with a few glands at the apex. Stipules 
variable in size, generally present, entire or serrate, often large and 
foliaceous on the later shoots. Male catkins 1} to 3 inches long, with 
the scales pale yellow, broader towards the apex than in the female 
catkins, generally hairy towards the base. Stamens surrounded by a 
double nectary. Female catkins ‘more lax than the male, with nar- 
rower and more parallel-sided scales. Nectary single. Ovary in fruit 
1 inch long, reddish. Catkin-scales subpersistent, much shorter tan 
the capsules. 
The varieties appear to pass insensibly into each other. 
This willow can be confounded only with S. undulata, which has 
leaves of the same texture, but in 5. triandra they are shorter, the 
stipules are less acute, and the catkin-scales are glabrous on the out- 
side, at least towards the apex, and are destitute of the long, white, 
woolly hairs, which are so abundant inside the scales of S. undulata. 
S. triandra has also the style scarcely at all developed, and the stigmas 
much shorter than in S. undulata. 
S. contorta, Crowe, which is cultivated in Sussex under the name 
of French willow, appears not to be wild in Britain, and is considered 
by Mr. Borrer as most nearly identical with var. Hoffinanniana, but 
other writers refer it to var. a Hooker and Arnott make it a 
distinct variety, distinguished by furrowed young twigs, linear-lance- 
olate leaves green on both sides, and acuminate capsule. 
Almond-leaved Willow. 
French, Saule a trois étamines. German, Mandelblittrige Weide.
