Lysimachia. | XLVI, PRIMULACEM. 293 
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 
Anagallis arvensis. 3 
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. VU. all summer. 
V. TRIENTALIS. TRIENTALE. 
A single species, only distinguished from ZLysimachia ,by a somewhat 
different habit, and by the parts of the flower being usually in sevens in- 
stead of in fives, although these numbers are not quite constant. 
1, T.europeea, Linn. (fig. 656). Common Trientale.—Rootstock 
perennial and slightly creeping. Stems erect, simple, 3 to 6 inches high, 
bearing 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 pink, with a yellow ring, 
rather larger than in Lysimachia nemorum. Calyx-segments narrow. 
Corolla rotate. Stamens with slender filaments, and short, recurved 
anthers. 
In woods, in northern and Arctic Europe, Asia, and America, reappearing 
here and there in mountain woods of central Hurope. Local in the Scotch 
Highlands, more rare in the north of England, and unknown in Ireland. 
Fl. early summer. 
VI. GLAUX. GLAUX. 
A single species, distinguished from all Primulacee by the absence of 
any real corolla, the coloured campanulate calyx assuming the appearance 
of one, the stamens alternating with its lobes. Capsule opening in 2 or 4 
valves, 
1, G. maritima, Linn. (fig. 657). Sea Glaux, 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 5-lobed. Stamens about the same length, with slender fila- 
ments and small anthers, 
On sands, salt-marshes, and muddy places, near the sea, in Europe, 
_ northern Asia, and America, extending to the salt tracts and inland seas of 
central Asia. Common on the British coasts. #7. summer. 
VII. ANAGALLIS. PIMPERNEL. 
Procumbent or creeping herbs, with opposite leaves, and opposite axil- 
lary flowers on slender pedicels, Calyx deeply cleft into 5 narrow seg-
