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]

Etymology[]

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.

Phylogeny[]

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 cladogram has been reconstructed from nuclear and plastid DNA molecular characters (ITS, rps16 intron and trnK region).[5][6]

Taxonomy[]

The genus was described in 1844 by August Heinrich Rudolf Grisebach.[7] The type species is Rhynchocorys elephas.

Species[]

According to the Plant List, 8 species are recognized in the genus Rhynchocorys:[8]

  • Post
  • (L.) Griseb.
  • Albov
  • Nábělek
  • Richt. ex Stapf, possibly to be reduced under synonymy of R. elephas[citation needed]
