1, BE. angustifolium, Linn. (fig. 341). Willow Epilobe, French 
Willow, Rose-bay.—A handsome plant, simple or scarcely branched, 2 or 
4 feet high, glabrous or slightly hoary, but never hairy. Rootstock creep- 
ing. Leaves shortly stalked, lanceolate, entire or with very minute distinct 
teeth. Flowers large, purplish red, in long terminal racemes; the petals 
slightly unequal, entire, and spreading from the base; the stamens and 
styles inclined downwards. Stigma deeply 4-lobed. Pod 1 to 2 inches long, 
more or less hoary. 
On moist banks, and in moist open woods, chiefly in light soils, in Arctic 
and northern Europe, Asia, and North America, extending into the moun. 
tainous districts of central Europe and Asia. Widely spread over Britain, 
but not common, and in many places introduced. FV. summer. 
2. &. hirsutum, Linn. (fig. 342). Great EHpilobe, Great Willow- 
herb, Codlins-and-cream.—Stems stout and branched, 3 or 4 or even 5 feet 
high, the whole plant softly hairy. Leaves lanceolate, clasping the stem 
at the base, and bordered with small teeth. Flowers large and handsome ; 
the petals erect at the base, spreading upwards, and deeply notched. -Pod 
very long, quadrangular, and hairy. 
On the sides of ditches and rivers, and in wet places, throughout Europe 
and central and Russian Asia, except the extreme north. Abundant in 
England, but less common in Scotland. FV. summer. 
3. &. parviflorum, Schreb. (fig. 343). Hoary EHpilobe.—Some speci- 
mens of this plant look like the H. hirsutum on a small scale, others 
approach EH. montanum. It is distinguished from the former by its 
smaller stature and much smaller flowers. The lower leaves, also, and 
sometimes the upper ones, are shortly stalked; the middle ones usually 
sessile, but scarcely clasping the stem. From BE. montanum there is little 
to separate it but the soft hairs with which it is clothed, the narrower 
leaves with shorter stalis, and the rather larger flowers. But none of these 
characters appear to be quite constant, and it may possibly prove to bea 
mere variety of L. montanum. 
In Europe and western Asia, but not so common as #. montanum, and 
generally found in wetter situations. It has nearly the same range over 
Britain, excepting the extreme north of Scotland. VU. summer. 
4, &.montanum, Linn. (fig. 344). Broad Hpilobe-—Stems erect, 
simple or slightly branched, from 6 inches to a foot or more high, eylin- 
drical, without any decurrent lines or angles, and usually glabrous or 
slightly hoary ; the autumnal offsets usually short, and sometimes sessile. 
Leaves shortly stalked, or sometimes almost sessile, ovate or broadly Janceo- 
late, and toothed. Flower-buds erect or slightly nodding ; ovary downy,
