Flowers usually 1-3(-8). Pedicels glan¬dular. Sepals free or basally united, acute or obtuse. Petals yellow, twice or more the length of sepals, broadly ovate or obovate.

S. flagellaris is a very variable species with a wide geographic range. Many infra-specific taxa have been recognised. The type sub-species is described from Mt. Casbec, Caucasus and not found in our area; its distribution is in the Caucasus, main mountain chain, with a few localities N & S. of it.
However, following Hulten's revision of the complex, 4 subspecies have been recognised from our area.
