CAUCASICUM

Originally described in 1872. Dr. Praeger had not succeeded in seeing either living or dried specimens of this species when he wrote his monograph on the genus in 1932. However, Praeger does make an interesting reference on page 76 under S. caucasicum, to quote:” Boissier, who transcribed from Ruprecht’s MS. (Ruprecht made the original description from living material which he collected), remarks that from badly dried specimens seen by him he finds little in which the plant differs from S. tectorum except its few-flowered corymb and rather longer petals.” In 1935 this species was collected by Dr. Giuseppi and W.E.Th. Ingwersen in the Caucasus from an unspecified mountain above the Georgian Highway in the region of Mount Kasbek. The  type specimen of S. caucasicum was collected in Daghestan by Ruprecht, and in many respects the specimen collected in 1935 corresponds with the description of Ruprecht and the observation made by Boissier. After all this said, there still remains some doubt concerning the plants under cultivation as the type specimen did have somewhat pubescent leaves, and until it is possible to see living material from the original locality, namely Daghestan, this point cannot be finally settled.

The plant under cultivation has rather few-leaved rosettes, about 2 to 3,5 cm in diameter. Rosette leaves spathulate, abruptly contracted, mucronate with dark brown apex and edged with short cilia, and just a very few hairs on back surface, otherwise glabrous. Offsets are numerous and carried on long stolons. The flowers are red.
