David, I believe there are somewhere in the region of 140 - 150 endemic plants in Cyprus.
Regarding this one, Dianthus strictus var troodi, our friend, Yiannis Christofides, in his book 'Illustrated Flora of Cyprus' describes it as;
Perrenial herb,to 50cm high, stems slender, flowers solitary at the ends of branches, calyx bracts 6-8, the lower elliptic, upper obovate, cuspidate with a broad membranous margin, petals pink. Alt 0-1960 m, fl May-Aug.
The photo was taken of ours in May last year. It is not very clear and the colour has been washed out, it is much more of a pink than it appears.
It has not yet flowered this year.
