LEUCANTHUM / KINDINGERI
S. leucanthum : Elem. Fl. Bulg. 30 (1883). This species was first collected and described from specimens found in the Rila Mountains, Bulgaria. The distribution of this species is apparently limited to the Rila Mountains where it has been re-collected a number of times in the 1930’s. The following is a general description: rosettes 2,5 to 5 cm in diameter, flattish with the inner leaves closed and the outer ones more or less erect. Leaves of rosettes are elongate-cuneate, widest near apex and finely pubescent on both faces, ciliate on edges with hairs of unequal lenght, colour of leaves can vary from pale yellow-green to dark green with a dark pronounced apex; this in some forms almost nonexistent.
Stolons are stout, about 5 to 8 cm in lenght. Lower stems are tall and quite slender with a small inflorescence, petals greenish-yellow, filaments vary from white to purple in individual forms, anthers yellow. This species is quite similar to S. kindingeri (Adamovic), the difference, although S. leucanthum is variable, is that the rosettes are less open and with many more leaves, also much longer stolons. In spite of the hairy nature of its rosettes, S. leucanthum is not a difficult species to grow, but it remains rather rare under cultivation as it increases slowly and is inclined to flower too much.
