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 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. 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 ...

Cistus Incanus
''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. ''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 ''Halimium'', ''Helianthemum'' and '' Tuberaria'', all in the family Cistaceae. The common name ''gum cistus'' is applied to resin-bearing species, especially ''C. ladanifer''. 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 have showy 5-petaled flowers ranging from ...

Pakaraimaea Dipterocarpacea
''Pakaraimaea'' is a genus of trees in the family Cistaceae. The genus contains a single species, ''Pakaraimaea dipterocarpacea'', from South America. 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.

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'', it generally went unrecognized by taxonomists and its species were included in a broad concept of ''Helianthemum'' throughout much of the 1800s and 1900s.

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 ''Lechea'' is based primarily in eastern North America and contains about 18 species referred to as "pinweeds." Most are low-growing herbs with narrow leaves and may 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 Anders Celsius (; 27 November 170125 April 1744) was a Swedish astronomer, physicist and mathematician. He was professor of astronomy at Uppsala University from 1730 to 1744, but traveled from 1732 to 1735 visiting notable observatories in Ger .... S ...

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. The leaves are in a rosette at the base of the plant, and then in opposite pairs up the stem; they are simple oval, 2–5 cm long and 1–2 cm broad. The flowers are 2–5 cm diameter, with five petals, yellow with a red spot at the base of each petal, the red spot acting as a 'target' for pollinating insects. ''Tuberaria'' species are used as food plants by the larvae of some Lepidoptera species including the ''Coleophora ''Coleophora'' is a very large genus of moths of the family Coleophoridae.

''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. The leaves are opposite, simple oval, 1–5 cm long and 0.5–2 cm broad, varying from glossy green to tomentose grey-green. The flowers are 1.5–4 cm diameter, with five petals, white or yellow; in some species the flowers are bicoloured with a dark red or brown basal spot on each petal to act as a nectar guide for pollinating insects. ;Selected species *'' Halimium alyssoides'' *'' Halimium atriplicifolium'' *'' Halimium calycinum'' (syn.

Soil
Soil, also commonly referred to as earth or dirt Dirt is an unclean matter, especially when in contact with a person's clothes, skin, or possessions. In such cases, they are said to become dirty. Common types of dirt include: * Debris: scattered pieces of waste or remains * Dust: a gener ..., is a mixture of organic matter, minerals, gases, liquids, and organisms that together support life. Some scientific definitions distinguish ''dirt'' from ''soil'' by restricting the former term specifically to displaced soil. Soil consists of a solid phase of minerals and organic matter (the soil matrix), as well as a Porosity, porous phase that holds Soil gas, gases (the soil atmosphere) and water (the soil solution). Accordingly, soil is a three-state of matter, state system of solids, liquids, and gases. Soil is a product of several factors: the influence of climate, terrain, relief (elevation, orientation, and slope of terrain), organisms, and the soil's parent materials (ori ...
