Oscularia deltoides leaves

The paired leaves of Oscularia deltoides display the spaced, pink to purple-tipped teeth along their margins and the keels at their backs. The upper (or inner) leaf surfaces are slightly concave with faint signs of wrinkling, as if they would appreciate some rain.

The opposite positioning of leaf pairs reveals the slight inequality in some of the pairs, the fusing of pairs at the base not visible here. Oscularia leaves are always covered in a white waxy layer (Smith, et al, 1998; iNaturalist).
