The toothwort is a protocarnivorous plant.‹See TfD› Most of the plant consists of a branched whitish underground stem closely covered with thick fleshy colourless leaves, which are bent over so as to hide the under surface; irregular cavities communicating with the exterior are formed in the thickness of the leaf. On the inner walls of these chambers are stalked hairs, which when stimulated by the touch of an insect send out delicate filaments by means of which the insect is killed and digested.

  • Common toothwort (Lathraea squamaria) is parasitic on the roots of hazel and alder, occasionally on beech, in shady places such as hedge sides. Lathraea squamaria is widespread in Europe.
  • Purple toothwort (Lathraea clandestina) grows on the roots of alder, poplar and willow At Arduaine Garden in Argyll in the absence of the three well-known hosts it grows on the roots of a variety of ornamental trees and shrubs; in the same garden cats are frequently seen to roll in the flowers and to eat them. It differs in the dark purple flowers being produced one on each stem. Purple toothwort grows in Middle and South Europe: Western Belgium, Western and Central France and Northern Spain, and locally in Central Italy. Elsewhere, especially in the British Isles, the plant is locally naturalized in parks and old gardens.
  • Rhodope toothwort (Lathraea rhodopaea) is common in the Rhodope Mountains and Rila mountain range in southeastern Europe.

    In Pavel Ivanovich Melnikov's "In the Forests" a Russian wise woman (znakharka) calls this plant Peter's Cross and says it protects against devils but only if collected with a prayer to God.

    Etymology

    The genus name Lathraea derives from the ancient greek λαθραῖος (lathraîos), meaning "clandestine", which is a reference to the fact that it is inconspicuous until it flowers.
