A considerable genus, spread over the northern hemisphere in Europe, 
Asia, and America.

Leaves lanceolate. Flowers in axillary racemes, Lobes of the

Stems procumbent or trailing. Peduncles 1- ‘flowered, “axill ary: 
Flowers small, rotate. Calyx-segments very narrow ; . 4 2. nemorui. 
Flowers large, almost campanulate. Calyx-segments broad . 3. L. Nummularia. 
Besides the above, Z. ciliata, Linn., a North American species, has 
been gathered apparently wild in Cumberland and near Dumbarton. It 
is an erect plant, like Z. vulgaris, but with fewer flowers on longer 
pedicels, the corolla more rotate and paler coloured, fringed at the edge, 
and the stamens free and spreading. 
1. L. vulgaris, Linn. (fig. 654). Common L., Loosestrife.—Stem erect, 
branched, 2 to 3 feet high, and more or less downy. Leaves usually 
in whorls of 3 or 4, rather large, broadly lanceolate or nearly ovate. 
Flowers in short, compound racemes, or panicles, in the upper axils 
and at the summit of the branches, forming a terminal, leafy panicle. 
Segments of the calyx lanceolate and pointed, varying much in breadth, 
and more or less ciliate on the edges. Corolla yellow, rather campanu- 
late than rotate, deeply divided into 5 broad lobes. Stamens connected 
at the base into a cup enclosing the ovary. 
On shady banks, and along streams, in Europe and Russian Asia, from 
the Mediterranean and the Caucasus to the Arctic Circle. Frequent in 
England, local in Ireland, rare in Scotland. Fl, summer, rather late. L. 
punctata is a marked variety of this species, not uncommon in Germany 
and south-eastern Europe, and occurring, mixed with the common form, 
in north-western England and south-western Scotland. It has the 
pedicels usually 1-flowered in the axils of the stem-leaves, the sepals 
rather narrower, and the lobes of the corolla fringed with minute 
glandular hairs; but none of these characters are constant. . 
2. L. thyrsiflora, Linn. (fig. 655). Z'ufted [.—Stem erect, simple, 
1 to 2 feet high, sometimes slightly downy. Leaves sessile, lanceolate, 
2 to 3 inches long. Flowers small and yellow, in dense axillary racemes, 
more or less pedunculate, but always shorter than the leaves. Sepals 
and petals narrow, the stamens and styles very prominent, and all the 
parts of the flower as often in sixes as in fives. 
On wet banks, and along streams, in central and northern Europe, and 
northern Asia and America, extending to the Arctic Circle. In Britain, 
confined to northern England and central Scotland. Fl. swmmer. 
3. L. Nummularia, Linn. (fig. 656). Moneywort, Creeping Jenny.— 
Stems prostrate, trailing to the length of 1 to 2 feet, often rooting at 
the nodes. Leaves opposite, broadly ovate or rounded, very obtuse, 
on short stalks. Flowers yellow, large and handsome, on axillary 
peduncles not so long as the leaves ; the divisions of the calyx broadly 
ovate and pointed ; the corolla concave, deeply divided into 5 ovate 
lobes. Stamens erect in the centre, with the filaments slightly connected 
at the base. 
On banks, under hedges, and in moist pastures, all over Europe, except 
the extreme north, and eastward to the Caucasus. Not uncommon in
