The leaves of Crassothonna sedifolia are alternate, often mainly near the stem-tips.The specific name, sedifolia, is derived from the Latin words sedi meaning to sit and folia meaning leaves, referring to the absence of leaf petioles or their general near-absence.
The leaves are short, succulent, grey-green cylinders or ellipsoids, some tending to obovoid and occasionally nearly spherical. Mostly rounded at the tips in picture, there is sometimes more evidence of a small, pointed tip that may become brownish. The leaves are about 5 mm to 10 mm long and 4 mm wide.
The plant in picture has lost moisture causing the surface wrinkling, quickly fixed by a little rain. The plant is palatable to stock and game, much browsed (Manning, 2009; Shearing and Van Heerden, 2008; Le Roux, et al, 2005; iNaturalist).
