Description: leaves alternate, rarely decussate, erect to spreading, occasionally squarrose, often somewhat fleshy and (sub) terete; leaf surface flat to somewhat involute but margins not rolled, both leaf surfaces lacking hairs except sometimes in young growth; both leaf surfaces usually distinctly and densely glandular-punctate with usually small, sunken, pellucid glands, no veins visible except midrib; leaves often viscid with a clear, shiny resin. Capitula solitary, in pairs, or 3–15 together, sessile or peduncles up to 25 mm long. Receptacle usually paleate (epaleate in three species). Ray florets 4–25, cypselas glabrous or (usually) densely pilose, disc florets 8–65, cypselas glabrous, glandular or sparsely pilose, rarely sterile. Pappus of more-or-less connate, lacerate scales <2 mm long, in one species some additional barbellate bristles sometimes present (Oe. sedifolia). Fourteen species, occurring in the more arid habitats in the GCFR (arid fynbos, renosterveld, or succulent karoo); one species in the Drakensberg.

Cytology: all species have been investigated and are diploids with 2n = 14 (Bremer, 1976a).
