Cistaceae
The Cistaceae are a small family of plants (the rock-rose or rockrose family), mostly shrubs, which are profusely covered by flowers in the spring and summer. This family consists of about 170-200 species in eight genera that are not very distinct, distributed primarily in the temperate areas of Europe and the Mediterranean basin, but also found in North America; a limited number of species are found in South America. Most Cistaceae are subshrubs and low shrubs, and some are herbaceous. They prefer dry and sunny habitats. Cistaceae grow well on poor soils, and many of them are cultivated in ga

半日花科（学名：Cistaceae）属真双子叶植物锦葵目，共包括8属约170-200余种。 目录 1 分布 2 特征 3 分类 4 参考文献 5 外部链接 分布 本科主要分布在北温带气候干旱、阳光比较强烈的地区，如地中海沿岸、北美，也有少数种分布在南美。中国只有一属一种—半日花（Helianthemum polifolium DC.），主要分布在新疆、内蒙一带。 特征 本科大部分为灌木或亚灌木，也有部分种为草本，被有星状毛；单叶对生或有时互生；花两性，辐射对称，花瓣5，偶有3，花开放的时间很短就凋谢，因此得名；果实为蒴果。 本科植物由于对土壤要求不高，被广泛种植在园林中。其根常有块菌共生，因也常被欧洲人用来培植块菰。有的品种也可以提炼香精。 分类 1981年的克朗奎斯特分类法将半日花科分到堇菜目中，1998年根据基因亲缘关系分类的APG 分类法将其列入锦葵目。 参考文献 Chevalier, G., D.

The Cistaceae are a small family of plants (the rock-rose or rockrose family), mostly shrubs, which are profusely covered by flowers in the spring and summer. This family consists of about 170-200 species in eight genera that are not very distinct, distributed primarily in the temperate areas of Europe and the Mediterranean basin, but also found in North America; a limited number of species are found in South America. Most Cistaceae are subshrubs and low shrubs, and some are herbaceous. They prefer dry and sunny habitats. Cistaceae grow well on poor soils, and many of them are cultivated in gardens.
They often have showy yellow, pink or white flowers, which are generally short-lived. The flowers are bisexual, regular, solitary or borne in cymes; they usually have five, sometimes three (Lechea), petals. The petals are free, usually crumpled in the bud, and sometimes in the open flower (e. g. Cistus incanus). The flowers have five sepals, the inner three of which are distinctly wider, and the outer two are narrow and sometimes regarded as bracteoles. This sepal arrangement is a characteristic property of the family.
