Cistaceae
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 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, petals ('' Lechea''). The petals are free, usually crumpled in the bud, and sometimes in the open flower (e. g. '' Cistus incanus''). It has five sepals, the inner three of which a ...

Cistus
''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, Spain, Italy, Greece, through to the Middle East, and also on the Canary Islands. ''Cistus'', with its many hybrids and cultivars, is commonly encountered as a garden flower. The common name rockrose (rock rose in the UK) is applied to the species, a name also shared by the related genera '' Helianthemum'' and '' Tuberaria'', all in the family Cistaceae. The common name ''gum cistus'' is applied to resin-bearing species, especially ''C. ladanifer''. Sometimes known as 'Pheasant's Compromise' Description The leaves are evergreen, opposite, simple, usually slightly rough-surfaced, 2–8 cm long. In a few species (notably ''C. ladanifer''), the leaves are coated with a highly aromatic resin called labdanum. They ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Crocanthemum
''Crocanthemum'' is a genus of flowering plants in the family Cistaceae. They are native to both North and South America where they are widespread. The common name frostweed relates to the ice crystals which form from sap exuding from cracks near the base of the stem in the late fall. ''Crocanthemum'' are herbaceous perennials or subshrubs with alternate leaves. With the exception of species in California, they generally produce two types of flowers: showy, yellow chasmogamous (cross-pollinated) produced earlier in the growing season, followed by cleistogamous (self-pollinated) flowers that are smaller and lack petals. All species of ''Crocanthemum'' are fire tolerant and are found in open habitats. Although the genus was first named in 1836 to encompass New World species of ''Helianthemum ''Helianthemum'' (), known as rock rose, sunrose, rushrose, or frostweed, [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pakaraimaea Dipterocarpacea
''Pakaraimaea'' is a genus of trees in the family Cistaceae. The genus contains a single species, ''Pakaraimaea dipterocarpacea'', from South America. It was formerly placed in subfamily Pakaraimoideae of the family Dipterocarpaceae. The species is found in the western highlands of Guyana and in adjacent Bolivar State in Venezuela. It maintains strong ectomycorrhizal associations with a wide variety of fungal species. The trees can sometimes be seen forming large stands in the western Guyanas. Taxonomy As of APG IV, the species has been moved out of the Dipterocarpaceae (formerly in subfamily Pakaraimoideae) and is now placed within an expanded Cistaceae due to molecular evidence showing that it is sister to the remainder of Cistaceae.

Lechea
''Lechea'' (pinweed) is a genus in the family Cistaceae of the order Malvales.USDA, NRCS. 2014. The PLANTS Database (http://plants.usda.gov, 1 December 2014). National Plant Data Team, Greensboro, NC 27401-4901 USA. The genus contains about 18 species referred to as "pinweeds" primarily in eastern North America. Most are low-growing herbs with narrow leaves and many small flowers that resemble pinheads. Linnaeus named the genus ''Lechea'' for Swedish botanist Johan Leche (1704–1764), who taught in Finland and is regarded as the father of Finnish meteorology and space research, based on his documentation of the northern lights and early measurements of air temperature in collaboration with Anders Celsius. Species 18 species are accepted. *'' Lechea cernua'' *'' Lechea cubensis'' *'' Lechea deckertii'' *'' Lechea divaricata'' *'' Lechea intermedia'' *''Lechea lakelae'' *'' Lechea maritima'' *''Lechea mensalis'' *''Lechea minor'' *''Lechea mucronata'' *''Lechea pulchella ...

Tuberaria
''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.

Stamen
The stamen (: stamina or stamens) is a part consisting of the male reproductive organs of a flower. Collectively, the stamens form the androecium., p. 10 Morphology and terminology A stamen typically consists of a stalk called the filament and an anther which contains sporangium, microsporangia. Most commonly, anthers are two-lobed (each lobe is termed a locule) and are attached to the filament either at the base or in the middle area of the anther. The sterile (i.e. nonreproductive) tissue between the lobes is called the Connective (botany), connective, an extension of the filament containing conducting strands. It can be seen as an extension on the dorsal side of the anther. A pollen grain develops from a microspore in the microsporangium and contains the male gametophyte. The size of anthers differs greatly, from a tiny fraction of a millimeter in ''Wolfia'' spp up to five inches (13 centimeters) in ''Canna iridiflora'' and ''Strelitzia nicolai''.

Sepal
A sepal () is a part of the flower of angiosperms (flowering plants). Usually green, sepals typically function as protection for the flower in bud, and often as support for the petals when in bloom., p. 106 Etymology The term ''sepalum'' was coined by Noël Martin Joseph de Necker in 1790, and derived . Collectively, the sepals are called the ''calyx'' (plural: calyces), the outermost Whorl (botany), whorl of parts that form a flower. The word ''calyx'' was adopted from the Latin ,Jackson, Benjamin, Daydon; A Glossary of Botanic Terms with their Derivation and Accent; Published by Gerald Duckworth & Co. London, 4th ed 1928 not to be confused with 'cup, goblet'. The Latin ''calyx'' is derived from Greek 'bud, calyx, husk, wrapping' ( Sanskrit 'bud'), while is derived from Greek 'cup, goblet'; both words have been used interchangeably in botanical Latin.
