Description
It is a ruderal species. [1]
"Erect, profusely branched perennial, 3-8 dm tall, the stems pubescent. Especially about the nodes. Leaves glandular-punctate, opposite, ovate-lanceolate to rhombic-ovate, 1-3 cm long, 6-16 mm wide, the distal ½-2/3 serrate. Flowers axillary, usually solitary, pedicel shorter than the petiole of the subtending leaf; calyx 4-parted, 1.5-2 mm long, the lobes widely ovate to elliptic, equaling or much exceeding the tube; corolla 4-parted, white, rotate, regular, the throat lanose, lobes ca. 1 mm long; stamens 4. Capsule subglobose to widely ellipsoid, ca. 2 mm long or broad." [2]
