Leaf: simple, alternate or opposite [whorled], often +- reduced, entire or not, petioled or not, stipuled or not. Inflorescence: raceme- or panicle-like cymes or flowers 1. Flower: generally bisexual, +- radial; sepals 3 or 5 (outer 2 often narrower), free or fused at very base, often persistent in fruit, 3 twisted in direction opposite that of petals; petals [0(3)]4--5, generally ephemeral; stamens (3--10) many, free, often sensitive to touch, +- persistent in fruit or not; ovary superior, chambers 1 (or +- 3--12 from intruded parietal placentas), style 0--1, stigma 1(3), lobes 0 or 3--12. Fruit: loculicidal capsule, valves 3--12. Seed: [1--]3--many. Genera In Family: 8 genera, +- 175 species: temperate, especially southeastern United States, Mediterranean; some cultivated (Cistus; Crocanthemum; Tuberaria).

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.
