This Ochna serrulata leaf has an off-centre midrib. The blade parts bulge on both sides of the midrib, and curve down towards the tip. The lateral veins are less straight nearer the margins, and more inclined to fork there. The marginal teeth are not all similar seen close-up.
Fairly long, brownish and curved pedicels allow the flowers to nod. The shorter, greener, more bulging sepals shine. The non-shiny, also bulging, yellow petals outshine them (Venter, 2012; Coates Palgrave, 2002; Pooley, 1993; iNaturalist).
