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. [1]
Melampyrum species are used as food plants by the larvae of some Lepidoptera species, including the mouse moth (Amphipyra tragopoginis).
The phylogeny of the genera of Rhinantheae has been explored using molecular characters. [2] [3] 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 , Hedbergia , Bellardia , and Odontites .

Fagaceae is a family of flowering plants that includes beeches and oaks, and comprises eight genera with about 927 species. The Fagaceae are mostly deciduous but often evergreen trees and shrubs, characterized by alternate simple leaves with pinnate venation, unisexual flowers in the form of catkins, and fruit in the form of cup-like (cupule) nuts. Their leaves are often lobed and both petioles and stipules are generally present. Their fruits lack endosperm and lie in a scaly or spiny husk that may or may not enclose the entire nut, which may consist of one to seven seeds. In the oaks, genus Quercus, the fruit is a non-valved nut called an acorn. The husk of the acorn in most oaks only forms a cup in which the nut sits. Other members of the family have fully enclosed nuts. Fagaceae is one of the most ecologically important woody plant families in the Northern Hemisphere, as oaks form the backbone of temperate forest in North America, Europe, and Asia and one of the most significant sources of wildlife fodder.
The Scrophulariaceae are a family of flowering plants, commonly known as the figwort family. The plants are annual and perennial herbs, as well as one genus of shrubs. Flowers have bilateral (zygomorphic) or rarely radial (actinomorphic) symmetry. The Scrophulariaceae have a cosmopolitan distribution, with the majority found in temperate areas, including tropical mountains. The family name is based on the name of the included genus Scrophularia L.
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.
Paulowniaceae are a family of flowering plants within the Lamiales. They are a monophyletic and monogeneric family of trees with currently 7 confirmed species. They were formerly placed within Scrophulariaceae sensu lato, or as a segregate of the Bignoniaceae.
Orobanchaceae, the broomrapes, is a family of mostly parasitic plants of the order Lamiales, with about 90 genera and more than 2000 species. Many of these genera were formerly included in the family Scrophulariaceae sensu lato. With its new circumscription, Orobanchaceae forms a distinct, monophyletic family. From a phylogenetic perspective, it is defined as the largest crown clade containing Orobanche major and relatives, but neither Paulownia tomentosa nor Phryma leptostachya nor Mazus japonicus.
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.
Rehmannia is a genus of six species of flowering plants in the order Lamiales and family Orobanchaceae, endemic to China. It is the only member of the monotypic tribe Rehmannieae. Contrary to the immense majority of the taxa of Orobanchaceae, Rehmannia is not parasitic.
Resedaceae is a family of mostly herbaceous dicotyledonous plants comprising 107 known species in 8 to 12 genera:
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.
Bartsia is a genus of flowering plants in the family Orobanchaceae.
Bellardia trixago is a species of flowering plant in the family Orobanchaceae. 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.
Parentucellia is a small genus of flowering plants in the family Orobanchaceae containing about four species. They are known generally as glandweeds. The genus was named for Pope Nicholas V, whose surname was Parentucelli.
Melampyrum arvense, commonly known as field cow-wheat, is an herbaceous flowering plant of the genus Melampyrum in the family Orobanchaceae. It is striking because of the conspicuous spike of pink or purple terminal bracts which includes the flowers.
Rhinantheae is a tribe with less than 20 genera of herbaceous plants in the family Orobanchaceae.
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.
Tozzia is a monotypic genus of flowering plants within the broomrape family Orobanchaceae. It contains a unique species, Tozzia alpina.
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.
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.
