The longish, thin leaves of Lampranthus stenopetalus grow in opposite, equal pairs, spaced on the stems. The succulent leaves are nearly cylindrical to slightly triangular in cross-section and taper to pointed tips. Rough-surfaced, the leaf colouring is blue green, grey green or sometimes dark green.
Leaf dimensions are about 15 mm long and 1,5 mm wide (Smith, et al, 1998; iNaturalist; Wikipedia; https://asknature.org).
