Three populations of another beautiful Caucasian species Dianthus caucaseus were found and investigated. D. caucaseus is taxonomically close to D. grossheimii. It is found only in Caucasus and Kars (NE Anatolia). We studied and described three populations of this species on the northern slope of Geghama Mountain.
We have described five meadows in different parts of the area visited, we collected herbarium and made lists of the species for each of the sites. Special attention was paid to the populations of target rare Dianthus grossheimii and newly discovered Grossheimia ahverdovii.
Below are descriptions of the most remarkable sites visited on the fieldtrips
Sourb Khach mountain.
The site of particular interest is a small mountain, 2500m above sea level, with Sourb Khach church on it. The mountain has rather steep slopes (about 40-45 degrees) and a crater area of about 400m in diameter. The north-western slope is covered with subalpine meadow with a total area of about 2 hectares. There are a number of beautiful and comparatively rare representatives of Armenian flora such as Aconitum anthorra (density: 2-3 plants in 100 m2), Dracocephalum ruyschiana (3-5 plants in 100 m2) , Dianthus caucaseus (7-15 plants in 100 m2), Vicia cracca (15-25 plants in 100 m2) . The slopes are grazed at the lower altitudes (up to 2300m) and the only potential threat to the meadow may be recreation as the church is a popular pilgrimage site for locals
