Hibiscus pusillus three-lobed leaf

Some Hibiscus pusillus leaves are three-lobed, the one in picture quite deeply. The lateral lobes are oblong, ending in three large teeth at their tips. The marginal teeth on the central lobe are more in number and smaller in size, commencing nearly halfway up the leaflet blade sides with angled tips bent back slightly.

The dark-green leaflet blades are concave on top, darker than the stem. Longitudinal lines angle up and outwards, or curve out upon the blades that appear rigid and thickish.

The ascending petiole is channelled on top, angled up more sharply than the blade (Curtis-Scott, et al, 2020; Vlok and Schutte-Vlok, 2015; Manning, 2009; Pooley, 1998; Van Wyk and Malan, 1997; Gledhill, 1981; iNaturalist).
