Saxifragaceae
Family of mainly herbaceous and subshrubby plants from mountainous and alpine zones of the northern hemisphere. Includes genera of succulent or semi-succulent rosettes such as Saxifraga, Bergenia and Chondrosea (= section Aizoon of Saxifraga). Many form dense cushions in rock crevices or stony soils. Circumpolar-alpine distribution.
Chondrosea
Chondrosea
Genus of succulent or semi-succulent plants of the Saxifragaceae family, corresponding to section Aizoon of Saxifraga in most modern treatments (APG IV). Species form compact rosettes of coriaceous or fleshy leaves frequently with calcareous incrustations on the margins. Distributed across European mountains (Alps, Pyrenees, Apennines, Carpathians) and Mediterranean regions. Most grow in limestone rock crevices. The name Chondrosea was established by Haworth. Many species were described by Jordan & Fourreau in the mid-19th century.

Large genus of plants in Saxifragaceae with numerous species adapted to alpine and rocky environments. Species of section Ligulatae (encrusted saxifrages) are particularly prized in cultivation for their rosettes covered with decorative calcareous encrustations.
Spathulata
Spathulata
Genus of Saxifragaceae plants, xerophytes adapted to arid and rocky conditions of eastern Europe and Asia Minor.
