Synonyms: Cheilanthes inaequalis (Kunze) Mett. var. inaequalis
Notholaena inaequalis Kunze
Notholaena tricholepis Baker
Common names:
Frequency: Frequent
Status: Native
Description:
Rhizome shortly creeping to suberect, c. 5 mm in diameter; rhizome scales narrowly lanceolate to linear in outline, margin entire, up to 2 cm long, rust-coloured. Fronds erect, tufted, herbaceous to coriaceous, shriveling up during the dry winter months. Stipe dark brown to black, up to 12(16) cm long, with short, fine white hairs and with scales similar to those of the rhizome at the base. Lamina ovate to lanceolate in outline, up to 22 cm × 11 cm, deeply 2-pinnatifid to 3-pinnatifid on the basal pinnae which are not reduced in size. Pinnae upper surface sparsely set with stiff hairs, lower surface densely covered with short hairs, turning reddish-brown with age, margins entire to lobed. Rhachis dark brown. Sori marginal, discrete at first but continuous when mature; indusium continuous or discontinuous.
Notes: Could be confused with C. eckloniana which has shiny golden-brown scales along the costae and costules, and basal pinnae that might be slightly reduced. The lower surface of the lamina of C. inaequalis var. buchananii is only sparsely covered with long, whitish hairs.
Derivation of specific name: inaequalis: unequal; referring to the unaequal structure of the basal pinnae.
Habitat: Cracks and crevices and in the shelter of boulders on granite sheetrock, in full sun or bases of rocks in woodland or grassland.
Altitude range: (metres) 1200 - 2350 m
Worldwide distribution: Widespread in southern and tropical Africa, also on Madagascar.
Zimbabwe distribution: N,W,C,E,S
Growth form(s): Lithophyte, terrestrial.
