1. E. angustifolium, Linn. (fig. 349), “[preneh Willow, Rose-bay.— 
A handsome plant, simple or scarcely branched, 2 or 4 feet high, 
glabrous or slightly hoary, but never hairy. Rootstock creeping. 
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 mountainous districts of central Europe and Asia. Widely spread 
over Britain, but not common, and in many places introduced. I. 
summer. [A cultivated form with shorter capsules, £. brachycarpum, 
Leight., occurs as a garden escape. ] 
2. EH. hirsutum, Linn. (fig. 343). 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. Fl. summer. 
3. E. parviflorum, Schreb. (fig. 344). Hoary #.—Some specimens 
of this plant look like the #. hirsutum on a small scale, others approach 
£. montanum. It is distinguished from the former by its smaller 
stature and much smaller flowers. The lower leaves, also, and some- 
times the upper ones, are shortly stalked; the middle ones usually — 
sessile, but scarcely clasping the stem. From £. montanum there is —
