Dianthus bolusii, called the mountain pink or bergangelier, is a species of flowering plant in the family Caryophyllaceae.[1]
Distribution
It is indigenous to the Northern Cape and Western Cape Province, South Africa , where it occurs on sandstone slopes, from the Cederberg in the north, eastwards to the Swartberg mountains, and southwards to the Du Toitskloof mountains and Swellendam area.[2]
In the west is recorded from the Skurweberg, Michell's Pass near Ceres, Tulbagh and near Riebeek-Kasteel. In the south it is recorded from the Sonderend and Buffeljags rivers in the Swellendam area. In the far east there is a possible outlying record from the mountains north of George.
The variety luteus (distinguished by its yellow-green flowers) is recorded from the Groot Drakenstein mountain near Paarl. [3]
Description
Dianthus bolusii is a tufted perennial reaching 40 cm, with linear (max.200mm x 3mm) blue-grey leaves, densely clumped near to the ground.[4]
The inflorescence is usually branched (1-8 flowers per stem), and rises c. 20 cm above the main leaf tufts. The flowers are cream to dark purple, and appear in Spring-Summer (Sept-Feb.).
The petals are oblanceolate, very deeply fringed, lacerate or fimbriate (and sometimes strongly downcurved/drooping). Occasionally, some specimens can bear darker red markings, near the bases of the petals. [5]
The calyx is 23-27 mm in length, with 2-6 bract-pairs. The bracts have narrow papery margins and reach c. 1/3 up the length of the calyx.[6]
