Primutacee—Dodecatheon. a77 
D, integrifolium is a much dwarfer species, having entire 
leaves and rather larger showy lilac-purple or crimson flowers ; 
and D. Jeffreyanwm, of recent introduction, is distinguished by 
its greater stature, fleshy midribs of its very large leaves, and 
by the tetramerous not pentamerous flowers. 
Soldanélla alpvna is an elegant diminutive mountain plant 
about 2 or 3 inches high with small petiolate rotundate cor- 
date crenate glandular leaves, and 2- or 3-flowered bracteolate 
scapes. Corolla blue or lilac, campanulate, limb finely fringed, 
capsule splitting transversely. S. monténa is a somewhat 
larger hairy plant; and S. minima and S. pusilla have one- 
flowered scapes, and more regular less deeply fringed corollas. 
5. LYSIMACHIA. 
Erect or creeping herbs with leafy stems and yellow or 
white, rarely purple flowers. Leaves simple, alternate, opposite 
or whorled. Flowers solitary, racemose or paniculate, axillary 
or terminal. Corolla rotate; lobes spreading or erect. Stamens 
5 or 6, included or exserted. Capsule 5 or 10-valved. There 
are about forty species, spread over the north temperate zone, 
less frequent in the southern hemisphere, and at great eleva- 
tions in the tropics. The name is from Avous, a release from, 
and wdyn, strife. 
1. L. vulgaris. Yellow Loosestrife.—This is an indigenous 
species of erect habit, about 3 feet high, usually found in damp 
places and on river-banks. Leaves opposite or whorled, ovate 
or lanceolate, acute, furnished with black glandular dots. 
Flowers deep yellow, in terminal panicled cymes, appearing in 
Summer. 
2. L. Nummularia. Creeping Jenny, Moneywort.— A 
prostrate creeping species with opposite rotundate cordate 
obtuse glabrous leaves and large solitary axillary yellow flowers 
having broad sepals, ciliate petals, and glandular connate fila- 
ments. This isa bandsome plant, abundant in some parts of 
England, and often transferred to the garden. L. némorwm, 
the Yellow Pimpernel, is another native trailing species with 
ovate acute leaves, narrow acute sepals, and free glandless fila- 
ments. 
3. DL. thyrsiflora, syn. Nawmbérgia thyrsiflora.—An erect 
species from 1 to 3 feet high with sessile lanceolate leaves and 
dense axillary racemes of yellow flowers, produced in Summer. 
This plant has been separated from the other species on account 
of the presence of small scales in the throat of the corolla and
