Cistaceae

Sage-leaved rock rose Cistus salvifolius, copyright Sten Porse.

Belongs within: Malvales.

The Cistaceae, rock roses, are a group of aromatic shrubs that are most diverse in the Mediterranean region with species also present in North and South America. In the last region they are represented by a single genus, Pakaraimaea, that was until recently classified with the Dipterocarpaceae. A number of species of the genera Helianthemum and Cistus are widely cultivated as ornamentals.

Characters (from the Angiosperm Phylogeny Website): Herbs to shrubs; root hairs absent; phloem not stratified; nodes 1:1; petiole bundles arcuate; cuticle waxes absent; hairs glandular, or simple, clustered, or stellate, each cell with a basal internal compartment; leaves usually opposite (occasionally spiral), lamina venation more or less conduplicate-curved, margin toothed, secondary veins pinnate or palmate, stipules present or absent; calyx and corolla more or less opposite, sepals 5, 2 outer smaller than others, petals crumpled in bud; anthers (3-)many and centrifugal; pollen often starchy; gynoecium opposite petals or median member abaxial, placentation usually parietal (occasionally axile), style hollow, stigmas small to capitate and/or lobed, dry, with multicellular multiseriate papillae; ovules (1-)2-many/carpel, straight, outer integument ca 2 cells across, inner integument 2-4 cells across, parietal tissue ca 2 cells across, nucellar cap ca 2 cells across, hypostase present; testa often mucilaginous; embryo more or less strongly curved, long, cotyledons thin, curved or folded, radicle short, stout.
