Morphology General Habit
Aquatic or terrestrial completely glabrous herb, varying in habit according to habitat.
Morphology Stem
Stem 6-38 cm. long, either erect or ascending and simple, rooting at lower nodes or at most nodes except for the apical ones, or stem widely trailing and rooting at nodes and emitting short, erect branches throughout, these simple or with 1-2 branchlets towards the apex, fleshy, somewhat thick but flaccid, green, mauve or purplish at the nodes; internodes up to 3·8 cm. long, the basal and median ones longer than the leaves, the uppermost equalling them or shorter.
Morphology Leaves
Leaves 5·5-20 x 1-5 mm., linear or oblong to oblong spathulate, acute to obtuse, sessile and connate at the base in a hyaline or purplish, 1-2 mm. long sheath, erect or erect-spreading but the undermost patent or slightly reflexed, fleshy, somewhat thick and rigid or nearly membranous on drying, light green, neither lineolate nor punctate near the margin.

Morphology Reproductive morphology Flowers Calyx
Calyx 0·75-1·25 mm. long, green or yellow-green; sepals oblong, subacute to rounded at the apex, connate at the base.
Morphology Reproductive morphology Flowers Corolla
Petals 1-1·75 mm. long, oblong or oblong-obovate, rounded at the apex, white, sometimes with carmine-red midrib or completely pinkish-white to carmine.
Morphology Reproductive morphology Flowers Androecium Stamens
Filaments 0·5-0·75 mm. long, carmine-red; anthers 0-15-0-25 mm. — long, transversely ovate or subcircular, purplish.
Morphology Reproductive morphology Fruits
Follicles 1-1·25 mm., obovoid, rounded at the top, contracted into the style, carmine; styles c. 0·5 mm. long, reflexed.
