420 CARYOPHYLLEA. XVIII. Mancura. XIX. 
7 S. Quite’nsis (H. B. et Kunth, gen. et spec. amer. 6. p. 19.) 
stems filiform, procumbent? leaves rather falcate ; peduncles 
axillary, 1-flowered, bearing 4*bracteas above the middle ; fruit- 
bearing peduncles straight, elongated ; flowers apetalous, some- 
what drooping. ©.H. Native of South America on the sandy 
banks of Rio Blanco at the height of 4800 feet. Valves of cap- 
sule revolute. 
Quito Pearlwort. Fl. May, Aug. PI. trailing. 
8 S. rascicuta‘ra (Poir. dict. 6. p. 390.) stems creeping, 
rooting, jointed ; branches somewhat erect; leaves secund in 
bundles ; peduncles axillary, 1-flowered. %.H. Native about 
Algiers. Very like S. proctimbens. Calyx glabrous, with short 
oval, obtuse, spreading lobes, which are reflexed after flowering. 
Petals white. 
Bundle-leaved Pearlwort. Fl. May, Aug. PI. 1 to 3 inches. 
Cult. None of the species of this genus are worth cultivating 
except the double-flowering variety of S. procúmbens and S. 
fasciculata : both should be kept in small pots well drained with 
potsherds, in a mixture of loam, peat, and sand; and the best 
way of increasing them is by dividing the plants at the roots. 
The rest of the species are only worth preserving in Botanical 
gardens; they require no care, but if once introduced to the 
garden, it will be hereafter quite impossible to extirpate them.

XIX. HYMENE’LLA (a diminutive of vunv, hymen, a 
membrane, on account of the thin little petaloid crown at the 
base of the petals.) Moc. et Sesse, fl. mex. icon. ined. D. C. 
prod. 1. p. 389. 
Lin. syst. Tetrdndria, Trigynia. Calyx 4-parted, spreading,

gardens. P. Carmelitarum, Sancti Angeli, Buff dnia tenuifdlia,

acute, glabrous; pedicels solitary, 1-flowered, axillary ; flowers

Cult. This plant should be kept in pots in a mixture of sand, 
loam, and peat, and placed in a green-house or frame during 
winter. It may be either increased by seeds or by dividing the 
plants at the root, but it is not worth cultivating except in bo- 
tanical gardens. 
XX. MOEHRI'NGIA (in honour of Paul Henry Gerard 
Moehring, a German physician, author of Hortus Proprius, 
1736.) Lin. gen. 264. Geert. fruct. 226. t.129. f. 11. D. C. prod.

1 M. muscosa (Lin. spec. p. 515.) leaves linear, connate ; 
segments of calyx flat, lanceolate, acute; flowers axillary, soli- 
tary. Y. H. Native of Europe in humid parts of moun- 
tains at the margins of woods. Lam. ill. t. 314. Schkuhr. handb.

imbricated ; flowers terminal, solitary. 2.H. Native of the 
Alps of Tenda. M. muscdsa, var. Balb. misc. bot. 20. t. 5. f.

Strict-leaved Moehringia. Fl. June, July. Pl. 4 foot. 
Cult. These pretty little alpine plants are well adapted for 
rock-work or to be grown in small pots. A mixture of sand, 
loam, and peat suits those grown in the latter way; and the best 
method of increasing them is by dividing the plants at the root.
