Rhynchocorys boissieri Contents | |
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. [1] [2]
The genus name Rhynchocorys derives from the two ancient greek words ῥύγχος (rhúnkhos), meaning "snout, muzzle, nose", and κόρυς (kórus), meaning "helmet, head", [3] [4] which is a reference to the shape of the style.
The phylogeny of the genera of Rhinantheae has been explored using molecular characters. [5] [6] 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.

The genus was described in 1844 by August Heinrich Rudolf Grisebach. [7] The type species is Rhynchocorys elephas.
According to the Plant List, 8 species are recognized in the genus Rhynchocorys: [8]
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.
Odontites is a genus of flowering plants in the family Orobanchaceae.
Euphrasia, or eyebright, is a genus of about 450 species of herbaceous flowering plants in the family Orobanchaceae, 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.
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.
Rhinanthus (rattle) is a genus of annual hemiparasitic herbaceous plants in the family Orobanchaceae, formerly classified in the family Scrophulariaceae. The genus consists of about 30 to 40 species found in Europe, northern Asia, and North America, with the greatest species diversity in Europe.
The painted tree-rat is a species of spiny rat from Brazil, restricted to north-eastern Bahia in eastern Brazil. It is the only species in the genus Callistomys.
The giant tree-rat is a species in the family Echimyidae, the spiny rats. It is the only species in the monotypic genus Toromys. It is endemic to Brazil, where it occurs in the flooded forest along the banks of the Amazon River and its tributaries.
The tuft-tailed spiny tree rat is a spiny rat species from South America. It is known from Brazil south of the Amazon River, where it has been found in grassland and gallery forest. It is the only species in the genus Lonchothrix. Very little is known about this rodent. It is small with an average adult weight of about 138 grams. It is nocturnal and solitary in habits.
Phyllomys is a genus of arboreal spiny rat, geographically restricted to the forests of eastern Brazil.
Echimys is a genus of the spiny rats family, the Echimyidae. Members of this genus are collectively called spiny tree-rats.
Dactylomys is the genus of South American bamboo rats They are arboreal members of the family Echimyidae.
Euryzygomatomys is a genus of South American rodents, commonly called guiaras, in the family Echimyidae. It contains two extant and one fossil species, found in Argentina, Brazil and Paraguay. They are as follows:
The armored rat is a species of rodent in the family Echimyidae. It is monotypic within the genus Hoplomys. It is found in Latin America, from northern Honduras to northwest Ecuador. It possesses a range of spines on its back and sides of the body.
Plagiodontia is a genus of rodent in the family Capromyidae.
Bartsia is a genus of flowering plants in the family Orobanchaceae.
Bellardia trixago is a species of flowering plant in the family Orobanchaceae. The only member of the monotypic genus Bellardia, it is known as trixago bartsia or Mediterranean lineseed. This plant is native to the Mediterranean Basin, but it is known in other places with similar climates, such as California and parts of Chile, where it is an introduced species and noxious weed.
Clyomys is a South American rodent genus in the family Echimyidae. It contains two species, found in tropical savannas and grasslands from circa 100 m (300 ft) to 1,100 m (3,600 ft) elevation in central Brazil and eastern Paraguay.
Rhinantheae is a tribe with less than 20 genera of herbaceous plants in the family Orobanchaceae.
Hedbergia decurva, formerly Bartsia decurva, is a species of flowering plants in the family Orobanchaceae.
Hedbergia longiflora, formerly Bartsia longiflora, is a species of flowering plants in the family Orobanchaceae.
