    The alternate leaves of Tetragonia hirsuta are short-stalked and hairy, the hairs stiff and spreading. The specific name, hirsuta, is a Latin word meaning hairy, a descriptor that suits the plant in general. There are no stipules.

    The leaf-shape is variable, lanceolate to ovate, sometimes elliptic or oblong. The leaf tapers to an acutely pointed tip and attenuates to the base. The pale cream midrib is conspicuous near the leaf base before sometimes becoming less visible higher up.

    The upper surface of the blade is flat or convex and the margins rolled under. Apart from the surface hairs the fleshy blades are also finely warty and sometimes shiny, the shades of green variable (Le Roux, et al, 2005; Bond and Goldblatt, 1984; JSTOR; iNaturalist).
