Nomenclature: Drosera cuneifolia L.f.

Publication: Linnaeus, C. [fil.] (1782 [“1781”]). Supplementum Plantarum Systematis Vegetabilium Editionis Decimae Tertiae, Generum Plantarum Editionis Sextae, et Specierum Plantarum Editionis Secundae. Brunsvigae [Braunschweig]: Impensis Orphanotrophei, p. 188

Description: Rosetted herb with sessile to semi-erect cuneate leaves. Inflorescence emerging erect and glandular along the entire length with eglandular hairs at the base. Flowers pink to lilac bearing three styles, divided once only at the base. 

Distribution in South Africa: WC

There are three main populations of D. cuneifolia: Table Mountain/Oudekraal, Silvermine/Muizenberg, and a population in the mountains north of Smitswinkel Bay

Habitat: In permanently wet and seasonally moist areas in Peninsula Sandstone Fynbos in the mountains around the Cape Peninsula.

Conservation: Although all populations of D. cuneifolia are entirely within Table Mountain National Park, too-frequent fires, invasive species, and climate change may threaten this range-restricted species. 

Phenology: Perennially growing, though plants in drier areas may die back during the driest months of summer after flowering. 

Taxonomy & Variation: Plants from Table Mountain tend to be smaller than those from Silvermine. Especially red plants from the summit might be introgressed with D. aliciae or D. admirabilis. Eric Green informally referred to one variant from Silvermine with slightly undulating leaf margins as "D. cuneifolia var. undulata" but this is not taxonomically significant not representative of the population at Silvermine. I have not observed plants from the newly-discovered Smitswinkel Bay population.
