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 saxosum

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.[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.

Genus-level cladogram of tribe Rhinantheae.

Rhinantheae

Melampyrum

Rhynchocorys

	Lathraea

	Rhinanthus

Core Rhinantheae

Bartsia sensu stricto (Bartsia alpina)

Euphrasia

Tozzia

Hedbergia
(including Bartsia decurva + B. longiflora)

Bellardia

	Neobartsia (New World Bartsia)

	Parentucellia

Odontites sensu lato
(including Bornmuellerantha
and Bartsiella)

The cladogram has been reconstructed from nuclear and plastid DNA molecular characters (ITS, rps16 intron and trnK region).[2][3]
