About Tetraria thermalis (L.) C.B.Clarke
Tetraria thermalis (L.) C.B.Clarke, commonly known as bergpalmiet, is a perennial plant species in the family Cyperaceae that is native to South Africa. This species is endemic to the Western Cape, with a range extending from the Cape Peninsula to Nature's Valley. It grows on sandy soils and sandstone slopes. Around 50 species are recognized in the genus Tetraria across Africa and Australasia, and approximately 38 of these species are found in the Cape fynbos. Currently, the genus Tetraria is polyphyletic and requires taxonomic revision. Tetraria thermalis is a pioneer species that recovers rapidly after fire events, and this rapid recovery supports the regrowth of other plant species. Mature individuals of T. thermalis reach around 2.5 meters in height. Stems are trigonous, bearing wiry, drooping yellow-green leaves. The leaves are narrowly sword-shaped, keeled, with scabrid margins lined with minute teeth that point toward the leaf apex. Its flowering stems are erect, triangular in cross-section, and grow well above the height of the leaves. It produces small, trigonous nutlets, which are often crowned by a persistent style; these nutlets are consumed by Chacma baboons.
