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] |

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 Albidus
''Cistus albidus'', the grey-leaved cistus, is a shrubby species of flowering plant in the family Cistaceae, with pink to purple flowers, native to south-western Europe and western north Africa. Description ''Cistus albidus'' grows up to tall. Its leaves are oblong to elliptical in shape, usually long by wide. They have three prominent veins and are densely covered with short hairs, producing a greyish-white appearance. The flowers are arranged in cymes of one to seven individual flowers, each across with five purple to pink petals and five sepals. Taxonomy and phylogeny ''Cistus albidus'' was first described by Carl Linnaeus in 1753 in ''Species Plantarum'' (p. 524). The specific epithet ''albidus'' means "whitish", referring to the leaves and shoots. A 2011 molecular phylogenetic study placed ''C. albidus'' as the sister to '' Cistus creticus'' in the purple and pink flowered clade (PPC) of ''Cistus'' species.

Labdanum
Labdanum, also called ladanum, ladan, or ladanon, is a sticky brown resin obtained from the shrubs ''Gum rockrose, Cistus ladanifer'' (western Mediterranean) and ''Cistus creticus'' (eastern Mediterranean), species of rockrose. It was historically used in herbal medicine and is still used in the preparation of some perfumes and vermouth, vermouths. History In ancient times, labdanum was collected by combing the beards and thighs of goats and sheep that had grazed on the cistus shrubs. Wooden instruments used were referred to in 19th-century Crete as ''ergastiri''; a ''lambadistrion'' ("labdanum-gatherer") was a kind of rake to which a double row of leathern thongs were fixed instead of teeth. These were used to sweep the shrubs and collect the resin which was later extracted. It was collected by the shepherds and sold to coastal traders. The resin was used as an ingredient for incense, and medicinally to treat colds, coughs, menstrual problems and rheumatism. as cited in Labdan ...

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'' case-bearers ''C. confluella'' (recorded on ''T. guttata'') and ''C. helianthemella'' (recorded on ''T. lignosa''). Species 12 species are accepted. *'' Tuberaria acuminata'' (Viv.) Grosser *'' Tuberaria brevipes'' (Boiss. & Reut.) Willk. *'' Tuberaria bupleurifolia'' (Lam.)

Flowering Plant
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (). The term angiosperm is derived from the Ancient Greek, Greek words (; 'container, vessel') and (; 'seed'), meaning that the seeds are enclosed within a fruit. The group was formerly called Magnoliophyta. Angiosperms are by far the most diverse group of Embryophyte, land plants with 64 Order (biology), orders, 416 Family (biology), families, approximately 13,000 known Genus, genera and 300,000 known species. They include all forbs (flowering plants without a woody Plant stem, stem), grasses and grass-like plants, a vast majority of broad-leaved trees, shrubs and vines, and most aquatic plants. Angiosperms are distinguished from the other major seed plant clade, the gymnosperms, by having flowers, xylem consisting of vessel elements instead of tracheids, endosperm within their seeds, and fruits that completely envelop the seeds. The ancestors of flowering plants diverged from the commo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Plants Of The World Online
Plants of the World Online (POWO) is an online taxonomic database published by the Royal Botanic Gardens, Kew. History Following the Convention on Biological Diversity, the Royal Botanic Gardens in Kew launched Plants of the World Online in March 2017 with the goal of creating an exhaustive online database of all seed-bearing plants worldwide. (Govaerts wrongly speaks of "Convention for Botanical Diversity (CBD)). The initial focus was on tropical African flora, particularly flora ''Zambesiaca'', flora of West and East Tropical Africa. Since March 2024, the website has displayed AI-generated predictions of the extinction risk for each plant. Description The database uses the same taxonomical source as the International Plant Names Index, which is the World Checklist of Vascular Plants (WCVP). The database contains information on the world's flora gathered from 250 years of botanical research. It aims to make available data from projects that no longer have an online ...

Paraphyly
Paraphyly is a taxonomic term describing a grouping that consists of the grouping's last common ancestor and some but not all of its descendant lineages. The grouping is said to be paraphyletic ''with respect to'' the excluded subgroups. In contrast, a monophyletic grouping (a clade) includes a common ancestor and ''all'' of its descendants. The terms are commonly used in phylogenetics (a subfield of biology) and in the tree model of historical linguistics. Paraphyletic groups are identified by a combination of synapomorphies and symplesiomorphies. If many subgroups are missing from the named group, it is said to be polyparaphyletic. The term received currency during the debates of the 1960s and 1970s accompanying the rise of cladistics, having been coined by zoologist Willi Hennig to apply to well-known taxa like Reptilia (reptiles), which is paraphyletic with respect to birds. Reptilia contains the last common ancestor of reptiles and all descendants of that ancest ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polytomy
An internal node of a phylogenetic tree is described as a polytomy or multifurcation if (i) it is in a rooted tree and is linked to three or more child subtrees or (ii) it is in an unrooted tree and is attached to four or more branches. A tree that contains any multifurcations can be described as a multifurcating tree. Soft polytomies vs. hard polytomies Two types of polytomies are recognized, soft and hard polytomies. Soft polytomies are the result of insufficient phylogenetic information: though the lineages diverged at different times – meaning that some of these lineages are closer relatives than others, and the available data does not allow recognition of this. Most polytomies are soft, meaning that they would be resolved into a typical tree of dichotomies if better data were available. In contrast, a hard polytomy represents a true divergence event of three or more lineages. Applications Interpretations for a polytomy depend on the individuals that are represented ...
