The thickly fleshy leaves of Felicia australis are alternate and narrowly oblong or linear with pointed tips, in picture turned brown on older leaves. Sessile, i.e. stalkless, the leaf attachment to the stem is broad, elongated downwards at its edges. The leaf margins are entire or sometimes slightly toothed. The margins are ciliate, i.e. sparse, bristly hairs are present in a row along them.
Tufts of small, young leaves have sprouted from the axils of old leaves in the photo. The soft stem here is thick, pale creamy green and slightly translucent (Manning, 2007; Le Roux, et al, 2005; Manning and Goldblatt, 1997; iNaturalist).
