Discussion | Genera 8, species 170–180 (5 genera, 40 species in the flora). Affinities of Cistaceae are evidently with Malvales. Members of Cistaceae are widely cultivated, especially cultivars of hybrids and species of Cistus, Crocanthemum, Halimium (Dunal) Spach, and Helianthemum Miller. Hairs on Cistaceae plants may be simple or stellate (comprising tight clusters or tufts of simple, unbranched hairs) and glandular or eglandular. Two species of Cistaceae have been collected in the flora area as waifs. Helianthemum nummularium Miller is known from Colorado, Missouri, and Oregon; it differs from species of Crocanthemum by the combination of glabrous abaxial surfaces of sepals and stellate-tomentose ovaries. Helianthemum salicifolium (Linnaeus) Miller is known from New York; it differs from species of Crocanthemum by its opposite leaves and erect, curved pedicels.
