The common name in Afrikaans for Glottiphyllum longum is volstruiskos (ostrich food). The long green succulent leaves grow in two opposite arrays often lying flat on the ground. New leaves emerge in the centre at the top of the latest additions.
The leaves tend to be wavy or slightly twisted rather than straight. The plant spreads by adding more rosettes, forming a clump. The flowers are similarly yellow in colour to others in the genus, mesemb-like with many oblong petals and a yellow cluster of stamens in the centre. The fruit is large, light brown with about twelve narrow triangular valves visible on the top.
This species had two noted varieties, viz. G. longum var. hamatum and var. heterophyllum, but apparently no longer as the two are sunken back into the main species (Smith, et al, 1998; Wikipedia; www.bakersfieldcactus.org; www.redlist.sanbi.org).
