Sepals 5, somewhat united at the base. Petals 5 (rarely by abortion fewer
or none), 2-cleft or lobed, often perigynous. Stamens 10 (or by abortion
3-8). Styles 3, sometimes 4. Capsule 1-celled, 3- (sometimes 4-) valved ;
valves usually 2-parted, membranaceous. Seeds numerous.—Herbs, mostly
inhabiting moist or shady places. Flowers terminal in dichotomous cymes,
or solitary.
The apparently lateral peduncles of several speeies are at first terminal but become
pseudo-axillary by the evolution of a branch in the axils of the upper leaves
which continues the stem. So also in Arenaria lateriflora, &c.
