little to separate it but the soft hairs with which it is clothed, the 
narrower (mostly alternate) leaves with shorter stalks, and the rather 
larger flowers. But none of these characters appear to be quite con- 
stant, and it may possibly prove to be a 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. FI. 
summer. [E. rivulare, Wablb., is an almost glabrous form, and £&. inter- 
medum, Merat., one with all the leaves alternate. | 
4, E. montanum, Linn. (fig. 345). Broad-leaved H.—Stems erect, 
simple or slightly branched, from 6 inches .to a foot or more high, 
cylindrical, 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 lanceolate, and toothed. Flower-buds erect or slightly nodding ; 
ovary downy, tapering into a stalk at the base, and crowned by a calyx 
2 or 3 lines long, divided below the middle into 4 reddish lobes. Petals 
pink, usually nearly twice as long, but sometimes scarcely exceeding the 
calyx, always deeply notched. Style divided at the top into 4 oblong, 
spreading, stigmatic lobes. Pod slender, 2 to 3 inches long. 
In waste and cultivated places, roadsides, woods, &c., throughout 
Europe and Russian and central Asia, and apparently in many other 
parts of the globe. Very abundant in Britain. Fl. summer. It varies 
much in the size of the flowers, which are in dry situations often nearly 
as small as in &. rosewm, from which it is then chiefly distinguished by 
the deeply-cleft stigma. [Z. montanum has usually opposite leaves ; 
the closely allied £. lanceolatum, Sebast. and Maur., which occurs in 
some of the southern counties of England, has these mostly alternate. 
It is sometimes regarded as a variety of £. rosewm.] 
5. E. roseum, Schreb. (fig. 346). Pale #.—An erect plant, glabrous 
or hoary when young, much resembling at first sight a small-flowered 
EL. montanum, but the leaves are narrower, on longer stalks, the lower 
ones generally opposite, with a raised line descending more or less along 
the stem from the junction of the leafstalk on each side, almost as in 
E. tetragonum. They vary from ovate-lanceolate to narrow-oblong, and 
from 1 to 3 inches in length. Flowers in a short, terminal, leafy, 
branched raceme or panicle; the limb of the calyx scarcely 2 lines 
long, and the notched petals not much longer. Buds erect or slightly 
nodding, the style ending in a club-shaped stigma, either entire or 
very shortly 4-lobed. . Pods from 1 to 2 inches long. 
Along ditches, and in moist situations, in Europe and Russian Asia, 
but not so common as either the preceding or the following species, 
nor extending so far to the north. Scattered over several parts of 
Britain, from Edinburgh southwards. It is often confounded with Z£. 
montanum or £. parviflorum. Fl. summer. 
6. E. tetragonum, Linn. (fig. 347). Square #.—Stems erect, often 
much branched, 1 to 2 feet high, glabrous or hoary with a very short 
down, and more or less angular from raised lines descending on each 
side from the margins of the leaves; the autumnal offsets often long 
and thread-like, with a fleshy bud at the extremity, more rarely short 
and scaly or leafy, as in #. montanum. Leaves sessile or nearly so, 
narrow, and toothed. Flowers small, in terminal leafy racemes, the
