Camissonia, sometimes commonly known as sun cup or sundrop, is a genus of annual and perennial plants in the evening primrose family Onagraceae.
 A total of 12 species are known, nearly all from western North America, especially in the California Floristic Province, but also one from South America.
 Previous circumscriptions of the genus had recognized up to 62 species before it was split among other closely related genera.
Cistus (from the Greek "kistos") is a genus of flowering plants in the rockrose family Cistaceae, containing about 20 species (Ellul "et al." 2002).
 They are perennial shrubs found on dry or rocky soils throughout the Mediterranean region, from Morocco and Portugal through to the Middle East, and also on the Canary Islands.
Hudsonia (goldenheather, poverty grass) is a small genus of three species of flowering plants in the family Cistaceae, native to North America.
 They are typical of sand dune habitats.
The Cistaceae are a small family of plants (rock-rose or rock rose family) known for their beautiful shrubs, which are profusely covered by flowers at the time of blossom.
 This family consists of about 170(-200) species in nine 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.
Helianthemum , known as rock rose, sunrose, rushrose, or frostweed, is a genus of about 110 species of flowering plants in the family Cistaceae.
 They are widely distributed throughout the Northern Hemisphere, especially in the Mediterranean.
 There are New World species, but it has been proposed that these be transferred to genus "Crocanthemum".
Pakaraimaea is a genus of flowering plants in the family Cistaceae in the American subfamily Pakaraimoideae.
Halimium (rockrose, false sun-rose, or halimium) is a genus of 12 species of evergreen or semi-evergreen subshrubs in the family Cistaceae, closely related to "Cistus".
 They are native to Europe, North Africa and Asia Minor, with the centre of diversity in the western Mediterranean region.
Tuberaria is a genus of about 12 species of annual or perennial plants in the rockrose family Cistaceae, native to western and southern Europe.
 They occur on dry, stony sites, often close to the sea.
Cistus ladanifer is a species of flowering plant in the family Cistaceae.
 It is native to the western Mediterranean region.
 Common names include gum rockrose, laudanum, labdanum, common gum cistus, and brown-eyed rockrose.
Dacrydium is a genus of conifers belonging to the podocarp family Podocarpaceae.
 Sixteen species of evergreen dioecious trees and shrubs are presently recognized.
 The genus was first described by Solander in 1786, and formerly included many more species, which were divided into sections A, B, and C by Florin in 1931.
 The revisions of de Laubenfels and Quinn (see references), reclassified the former section A as the new genus "Falcatifolium", divided Section C into new genera "Lepidothamnus, Lagarostrobos" and "Halocarpus", and retained Section B as genus "Dacrydium".
