Habitat
An acaulescent herb with radical, rosulate, bullate leaves dark green and shiny above and paler below, with flowers mostly hidden under the leaves. Bolus lumped his type material of G. capensis from Gnadouw Mountain (probably Nadouwsberg, 40 km E. of Graaff Reinet) and Oudeberg (probably Ouberg 20 km N.W. of Graaff Reinet) under one number, Bolus 818. The specimen in Bolus Herbarium from Gnadouw Mountain with notes by Bolus in his own handwriting is presumably the holotype rather than the one from Oudeberg marked 'typus auctoris', but not in Bolus's hand.

Guthriea capensis H. Bol. in Hook. Icon. PI. 1.1161 (1876); Marloth, Fl. S. Afr. 2,2: 200 (1925). Type: Cape, "in saxosis in monte Gnadouw-Sneeuwbergen in ditione Graaff Reinet", et "in monte Oudeberg prope Graaff Reinet in locis graminosis", Bolus 818 (BOL, holo.!; K!;PRE!; SAM!; Z!).
