Rhinantheae
Rhinantheae is a tribe with less than 20 genera of herbaceous plants in the family Orobanchaceae. Phylogeny The phylogeny of the genera of Rhinantheae has been explored using DNA markers. Three assemblages can be distinguished in this tribe: * ''Rhinanthus'' is the sister genus to ''Lathraea'', and then to ''Rhynchocorys''. These taxa are closely related to the core Rhinanteae. * In the core Rhinantheae, ''Odontites'' sensu lato, including ''Bornmuellerantha'' and ''Bartsiella'', is the sister genus to ''Bellardia'', including ''Parentucellia'' and ''Bartsia canescens'' + ''B. mutica''. These taxa are closely related to ''Hedbergia'' (including ''Bartsia decurva'' + ''B. longiflora'') and ''Tozzia''. In turn, these genera share phylogenetic affinities with ''Euphrasia'', and then with ''Bartsia'' sensu stricto (''Bartsia alpina''). * ''Melampyrum'' occupies an isolated, deep-branching position. The median crown age of Rhinantheae was estimated to be ca. 30 Myr. Systematics ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Melampyrum
''Melampyrum'' is a genus of about 20 species of herbaceous flowering plants in the family Orobanchaceae known commonly as cow wheat. They are native to temperate regions of the Northern Hemisphere. They are hemiparasites on other plants, obtaining water and nutrients from host plants, though they are able to survive on their own without parasitising other plants.Kim, K. and S. Yun. (2012)A new species of ''Melampyrum'' (Orobanchaceae) from southern Korea.''Phytotaxa'' 42 48-50. ''Melampyrum'' species are used as food plants by the larvae of some Lepidoptera species, including the mouse moth (''Amphipyra tragopoginis''). Phylogeny The phylogeny of the genera of Rhinantheae has been explored using molecular characters. ''Melampyrum'' appears as a distant relative of other genera of Rhinantheae. It is the sister group of two clades: (i) ''Rhynchocorys'', ''Lathraea'', and ''Rhinanthus'' ; and (ii) the core Rhinantheae containing ''Bartsia'', ''Euphrasia'', ''Tozzia'', ''Hedbergi ...

Euphrasia
''Euphrasia'', or eyebright, is a genus of about 450 species of herbaceous flowering plants in the family Orobanchaceae (formerly included in the Scrophulariaceae), with a cosmopolitan distribution. They are semi-parasitic on grasses and other plants. The common name refers to the plant's use in treating eye infections. Many species are found in alpine or sub-alpine meadows where snow is common. Flowers usually are borne terminally, are zygomorphic, and have a lower petal shaped like a lip. The most common flower colours are purple, blue-white, and violet. Some species have yellow markings on the lower petal to act as a guide to pollinating insects. Alternative names, mainly in herbalism, are ''Augentrostkraut, Euphrasiae herba, Herba Euphrasiae'' and ''Herbe d'Euphraise''. Use in herbalism and medicine The plant was known to classical herbalists, but then was not referred to until mentioned again in 1305. Nicholas Culpeper assigned it to the Zodiac sign Leo, claiming that it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Odontites
''Odontites'' is a genus of flowering plants in the family Orobanchaceae. Phylogeny The phylogeny of the genera of Rhinantheae has been explored using molecular characters. ''Odontites'' belongs to the core Rhinantheae. It is the sister genus to ''Bellardia'', and then to ''Tozzia'' and ''Hedbergia''. These taxa are closely related to the genus ''Euphrasia''. In turn, these five genera share phylogenetic affinities with ''Bartsia''.

Lathraea
''Lathraea'' (toothwort) is a small genus of five to seven species of flowering plants, native to temperate Europe and Asia. They are parasitic plants on the roots of other plants, and are completely lacking chlorophyll. They are classified in the family Orobanchaceae. The toothwort is a protocarnivorous plant. Most of the plant consists of a branched whitish underground stem closely covered with thick fleshy colourless leaves, which are bent over so as to hide the under surface; irregular cavities communicating with the exterior are formed in the thickness of the leaf. On the inner walls of these chambers are stalked hairs, which when stimulated by the touch of an insect send out delicate filaments by means of which the insect is killed and digested. Etymology The genus name ''Lathraea'' derives from the ancient greek (), meaning "clandestine", which is a reference to the fact that it is inconspicuous until it flowers.

Tozzia
''Tozzia'' is a monotypic genus of flowering plants within the broomrape family Orobanchaceae. It contains a unique species, ''Tozzia alpina''. While the plant in its young, vegetative stage is holoparasite, it becomes hemiparasite in its flowering stage. The originality of this species is therefore to combine half and full parasitism. The range of ''Tozzia alpina'' extends from the Pyrenees and the Alps to the Balkans and the Carpathians. Description Vegetative features ''Tozzia alpina'' is a herbaceous, perennial plant, reaching heights of . The quadrangular stem is hairless in the lower part, hairy on the edges in the middle and upper part. The simple, bright green leaves are broad, ovate, serrate, with a length of 1 to 3.5 centimeters, a rounded or slightly heart-shaped basis, and a sharp upper end. Reproductive features The flowering period is from June to August. The hermaphroditic zygomorph flowers are organized into a raceme inflorescence. The bracts have a ...

Rhynchocorys
''Rhynchocorys'' is a small genus of flowering plants belonging to the family Orobanchaceae, formerly classified in the family Scrophulariaceae. It is native to Europe, Morocco and Algeria. Etymology The genus name ''Rhynchocorys'' derives from the two ancient greek words (), meaning "snout, muzzle, nose", and (), meaning "helmet, head", which is a reference to the shape of the style. Phylogeny The phylogeny of the genera of Rhinantheae has been explored using molecular characters. ''Rhynchocorys'' is the sister genus to ''Lathraea'' and ''Rhinanthus''. These three genera share phylogenetic affinities with members of the core Rhinantheae: ''Bartsia'', ''Euphrasia'', ''Tozzia'', ''Hedbergia'', '' Bellardia'', and ''Odontites''. ''Melampyrum'' appears as a more distant relative. Taxonomy The genus was described in 1844 by August Heinrich Rudolf Grisebach. The type species is ''Rhynchocorys elephas''.

Hedbergia
''Hedbergia'' is a monotypic genus of flowering plants, initially classified in Scrophulariaceae, and now within the broomrape family Orobanchaceae. It contains a unique species, ''Hedbergia abyssinica''. It is an afromontane genus, widespread in grasslands and scrubs of the mountains of tropical Africa, and known from Ethiopia, Zaire, Uganda, Kenya, Tanzania, Malawi, Nigeria, and Cameroons. The genus name is a taxonomic patronym honoring the Swedish botanist Karl Olov Hedberg. Description ''Hedbergia abyssinica'' is a high, very hispid perennial plant, with subsessile thick leaves, and densely crowded, white to pink or magenta flowers. Phylogeny The phylogeny of the genera of Rhinantheae has been explored using molecular characters. ''Hedbergia'' belongs to the core Rhinantheae.

Bartsia
''Bartsia'' is a genus of flowering plants in the family Orobanchaceae. Bartsia grows in damp places, such as marshes and wet meadows, in several parts of the west of England and Wales and in southwest Scotland. Etymology ''Bartsia'' was named after Johann Bartsch (Latinized as Johannes Bartsius, 1709-1738), a botanist of Königsberg. The plant was named for him by his associate Carl Linnaeus, and the genus has been sometimes spelt as ''Bartschia''.
