Annual or perennial herbs or small shrubs. Leaves alternate, rarely pseudo-opposite, linear to (ob-)ovate. Indumentum variable, rarely glabrous. Inflorescences unbranched or 1–4-branched, ebracteose, bracteose, frondose, or reduced to solitary, axillary flowers. Calyx lobed 1/3rd to 1/2 of length. Corolla white to yellow, lobes subcircular to ovate-acuminate, lobes involute in bud. Anthers long protracted with pubescent apex, apically coherent, closing the corolla tube. Fruit dry, separating into one-seeded mericarpids each with two pits on the abaxial side, rarely dry drupes. Embryo curved.
2n = 14, 24, 28, 32, 42, 48.
A well-supported monophyletic group. All analyses resolve this genus as sister to Myriopus. Resolving phylogenetic relationships within Euploca await further research.
Cosmopolitan with centres of diversity in Africa, Australia, and tropical America.
