Primulacetz Dodecatheon. 377 



D. integri folium is a much dwarfer species, having entire 

 leaves and rather larger showy lilac-purple or crimson flowers ; 

 and D. Jeffreyanum, of recent introduction, is distinguished by 

 its greater stature, fleshy midribs of its very large leaves, and 

 by the tetramerous not pentamerous flowers. 



Soldanella alplna 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. montana 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 Xvcrty, a release from, 

 and //-a%7, 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 is a handsome plant, abundant in some parts of 

 England, and often transferred to the garden. L. nemorum, 

 the Yellow Pimpernel, is another native trailing species with 

 ovate acute leaves, narrow acute sepals, and free glandless fila- 

 ments. 



3. L. thyrsiflora, syn. Naumbergia 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
