292 THE PRIMROSE FAMILY. [Lytimachi*. 



England ; from York and Durham southward ; not indigenous in Scot- 

 land or Ireland. PI. summer and autumn. 



1. L. nemorum, Linn. (fig. 657). Wood L. A procumbent plant, 

 with the habit and rotate corolla of Anayattis arvensis, but with the 

 yellow flowers and the capsule of a Lysimachia. Stem slender, often 

 rooting at the base, 6 inches to a foot long. Leaves opposite, broadly 

 ovate, on short stalks. Pedicels slender, axillary, rather longer than 

 the leaves, each with a single, rather small flower. Calyx-segments 

 narrow and pointed. Corolla rotate, of a bright yellow. Stamens quite 

 free, with slender filaments. As the capsule ripens, the pedicels roll 

 round, as in AnagaHit arvensis. 



In woods and shady places, not uncommon in western Europe, 

 extending far northward in Scandinavia, and eastward through central 

 Europe to Transylvania. Generally distributed over Britain. Fl. all 

 summer. 



V. TRIENTALIS. TRIENTALE. 



A single species only distinguished from Lysimachia by a some- 

 what different habit, and by the parts of the flower being usually 

 in sevens instead of in fives, although these numbers are not quite 

 constant. 



1. T. europaea. Linn. (fig. 658). Trientale. Rootstock perennial 

 and slightly creeping. Stems erect, simple, 3 to inches high, bear- 

 ing at the top a tuft or irregular whorl of 5 or 6 leaves, varying 

 from obovate to lanceolate, usually pointed, the largest near 2 inches 

 long, with 2 or 3 small alternate leaves below the whorl. From 

 the centre of the leaves arise from 1 to 4 slender pedicels, about 

 as long as the leaves, each terminated by a single flower, white or pale 



S' ik, with a yellow ring, rather larger than in Lysimachia nemorum. 

 lyx-segments narrow. Corolla rotate. Stamens with slender fila- 

 ments, and short, recurved anthers. 



In woods, in northern and Arctic Europe, Asia, and America, re- 

 appearing here and there in mountain woods of central Europe. Local 

 in the Scotch Highlands, more rare in the north of England, and un- 

 known in Ireland. PI. early summer. 



VI. OLAUX. GLAUX. 



A single species, distinguished from all Primulacece by the absence of 

 any real corolla, the coloured campanulate calyx assuming the appear- 

 ance of one, the stamens alternating with its lobes. Capsule opening in 

 2 or 4 valves. 



1. G. maritima, Linn. (fig. 659). Sea Milkwort, Black Saltwort. 

 A low, decumbent, branching perennial, glabrous and often slightly 

 succulent, from 3 to 4 or 5, rarely 6 inches high, with a more or less 

 creeping rootstock. Leaves small, mostly opposite, sessile, ovate, 

 oblong or almost linear, and entire. Flowers of a pale pink colour, 

 not 2 lines long. Calyx deeply 6-lobed, Stamens about the same 

 length, with slender filaments and small anthers. 



On sands, salt-marshes, and muddy places, near the sea, in Europe,
