Leaf: generally simple, basal and/or cauline, generally alternate, generally petioled; veins +- palmate. Inflorescence: raceme or panicle, generally +- scapose. Flower: generally bisexual, generally radial; hypanthium free to +- fused to ovary; calyx lobes generally 5; petals generally 5, free, generally clawed, generally white; stamens 3, [4], 5, 8, or 10; pistils 1 (carpels +- fused, ovary lobed, chambers 1 or 2, placentas generally 2(3), axile or parietal or occasionally proximally axile and distally marginal in ovary lobes) or 2 (carpels free, placentas marginal), ovary nearly superior to inferior, occasionally more superior in fruit, styles generally 2(3). Fruit: capsule (generally 2(3)-beaked, valves generally 2(3), generally equal) or 2 follicles. Seed: generally many, small. Genera In Family: +- 30 genera, 600 species: especially northern temperate, arctic, alpine; some cultivated (Bergenia, Darmera, Heuchera, Saxifraga, Tellima, Tolmiea). Note: California Mitella moved to Mitellastra, Ozomelis, Pectiantia; Suksdorfia ranunculifolia to Hemieva. Parnassia moved to Parnassiaceae. eFlora Treatment Author: Michael S. Park & Patrick E.

(Note: any qualifiers in the taxon distribution description, such as 'northern', 'southern', 'adjacent' etc., are not reflected in the map above, and in some cases indication of a taxon in a subdivision is based on a single collection or author-verified occurrence).
MAP LEGEND View all CCH records All markers link to CCH specimen records. The original determination is shown in the popup window.
Blue markers indicate specimens that map to one of the expected Jepson geographic subdivisions (see left map). Purple markers indicate specimens collected from a garden, greenhouse, or other non-wild location.
Yellow markers indicate records that may provide evidence for eFlora range revision or may have georeferencing or identification issues.
