Involucre campanulate, 5-12 mm wide. Involucral bracts 40-85, outer ovate, inner gradually longer and oblong-obovate with a somewhat spreading, scarious apical limb, innermost very narrowly obovate-spatulate, also with a spreading, scarious apical limb, up to 12.5 mm long, up to 2.8 mm wide, dorsally gland-dotted, obtuse-rounded. Receptacle flat, epaleate. Ray-florets 12-25. Tube cylindrical, 3.2-5 mm long, glandular. Lamina narrowly elliptic, 4.5-11 mm long, 1.2-2.5 mm wide, 4-veined. Style 4.5-6.5 mm long; style-branches 0.8-2.4 mm long. Achenes as in disc-florets. Disc-florets 30-60, perfect or 9-sterile. Corolla 3.8-5.5 mm long, 0.6-1 mm wide. Tube cylindrical, glandular.

Diagnostic description

This species is a low shrub characterized by needle-shaped, pungent, closely set leaves. They have probably developed from a broader form. Although the vascular anatomy does not give us any clue, it seems as if the ventral side has become much reduced, where after the margins have met, resulting in a unifacial leaf. From: Bremer, K. 1976. The genus Relhania (Compositae). Opera Bot. 40: 1-85. [All rights reserved] As: Relhania acerosa (DC.) K.Bremer

Distribution

R. acerosa grows on sandstone rocks south of, in and around Lesotho. The apparent absence of the species on the inner mountains of Lesotho is probably due to insufficient collecting. From: Bremer, K. 1976. The genus Relhania (Compositae). Opera Bot. 40: 1-85. [All rights reserved] As: Relhania acerosa (DC.) K.Bremer
