Subspecies

This type splits into three subspecies:

• Saxifraga stellaris subsp. stellaris
• Brood Star saxifrage ( Saxifraga stellaris subsp. Prolifera ( Sternb. ) Temesy )
• Usually star - saxifrage ( Saxifraga stellaris subsp engleri P. Fourn; Syn: .. Saxifraga stellaris var hispida Dalla Torre, Saxifraga stellaris var robusta Engl, S. stellaris subsp alpigena Temesy. )

The Nominatunterart subsp. stellaris missing in Central Europe. It comes in Scandinavia, Scotland, Ireland, Iceland, in the south of Greenland and in the extreme northeast of Canada. Widely used in the mountains of southern and central Europe, from Spain to the Carpathians, the Ordinary Star saxifrage (p. stellaris subsp. Engleri ). The third subspecies, the brood - star saxifrage ( S. stellaris subsp. Prolifera ), carries in addition to or in lieu of flowers blossom leaf buds in the inflorescence.
