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.[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.

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]

  • Rhynchocorys boissieri Post
  • Rhynchocorys elephas (L.) Griseb.
  • Rhynchocorys intermedia Albov
  • Rhynchocorys kurdica Nábělek
  • Rhynchocorys maxima Richt. ex Stapf, possibly to be reduced under synonymy of R. elephas
  • Rhynchocorys odontophylla R.B.Burb. & I.Richardson
  • Rhynchocorys orientalis Benth.
  • Rhynchocorys stricta Albov
