The simple leaves of Ruttyruspolia 'Phyllis van Heerden' are opposite on long stalks. The leaf shape is ovate; the tips taper, the bases rounded to tapering. The leaves may turn yellow in autumn.
The softly textured and hairless green leaves are paler on their lower surfaces. Four to six lateral veins ascend from the midrib on either side to the margins and curve in; not opposite in pairs. Some net-veining is also visible, all the venation slightly recessed on the upper surfaces.
The bristle-like beginnings of an inflorescence are visible at the stem tip, as well as a couple of more developed buds growing from leaf axils close by (www.plantzafrica.com).
