Dianthus bolusii

Dianthus bolusii, sometimes called the Cape pink and commonly known as bergangelier (mountain carnation) in Afrikaans, is a tufted perennial reaching heights from 10 cm to 40 cm.

The blue-grey leaves are narrow and hairless. Joined in opposite pairs at the plant base, or clustered near the ground in a short sheath, the leaves appear grass-like. Leaf dimensions are 5 cm long and 3 mm wide.

The distribution of this South African endemic lies mainly in the Western Cape, possibly spreading somewhat into the Northern Cape and the Eastern Cape. The plant in picture was seen in the Little Karoo. 

It normally grows in sandy soil on rocky outcrops, mainly in fynbos. The habitat population is deemed of least concern early in the twenty first century (Vlok and Schutte-Vlok, 2015; iNaturalist; iSpot; http://redlist.sanbi.org).
