Dianthus thunbergii (Thunberg's wild pink) is a species of flowering plant in the family Caryophyllaceae.[1]
It is indigenous to the southwestern Cape, South Africa, where it occurs on rocky slopes from Swellendam in the Western Cape, eastwards into the Eastern Cape Province.[2]
Dianthus thunbergii is a spreading or tufted herbaceous perennial reaching 40 cm, with linear (50mm x 3mm) blue-grey leaves.
The inflorescence is usually sparsely branched and rises c. 20cm above the plants, bearing 2-5 flowers.
The flowers are usually pink (sometimes white), 15mm wide, and appear in Spring-Summer (Sept-Feb.). The petals are shortly fimbriate to dentate.[3]
The calyx is cylindrical and 20-30 mm in length. The lower half of the calyx is covered with 2-4 bract pairs. The bracts are lanceolate or acute to acuminate in shape.[4]
In the far western extent of its distribution range, D. thunbergii co-occurs with a related species, Dianthus albens, but D. thunbergii can be distinguished from the latter species by a combination of its longer calyx (20-30 mm long, rather than 12-18 mm); by the narrower lobes at the tip of its calyx (narrowly ovate, rather than deltoid-ovate); by the shape of the bracts at the base of the calyx (lanceolate-elliptic, rather than ovate-elliptic); by the number of bract pairs at the base of the calyx (2-4, rather than 1-3); by its uniformly dentate to shortly fimbriate petal tips (rather than entire-crenulate to rarely shallowly dentate); and by its seed capsule not extending beyond the calyx when ripe.
It also co-occurs with another related species, Dianthus caespitosus, but D. thunbergii can be distinguished from the latter species by its calyx which is shorter (20-30 mm, rather than 32-65mm long).[5]
