Perennial or sometimes biennial, amphibious herb from a shallow creeping rhizome, smooth throughout or thinly glandular-hairy in the inflorescence; stems decumbent to erect, 10-70 cm long/tall, rooting at the lower nodes, simple to much-branched at the base, somewhat fleshy.
Opposite, mostly unstalked, somewhat clasping-based, elliptic to broadly lanceolate, 2-8 (10) cm long, 1.5-3 times as long as wide, usually distinctly but remotely toothed.
Inflorescences several long, rather narrow, opposite, stalked racemes arising from the axils of upper leaves, the racemes of to 30 or more stalked flowers, the flower stalks upcurved, 3-8 mm long, as long as or slightly longer than the reduced linear-lanceolate bracts; corollas blue to pale violet with darker lines, saucer-shaped, 5-10 mm across, irregularly 4-lobed, the lobes much longer than the short tube, the lowest lobe narrower than the others; calyces 3-6 mm long, deeply 4-lobed, the lobes unequal, broadly lanceolate; styles 1.5-3 mm long, exserted; stamens 2.
Capsules, 2.5-4 mm long, a little longer than wide, plump, somewhat globe-shaped, scarcely notched at the tip; seeds numerous, flattened, 0.3-0.5 mm long.
