Contents

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.

Etymology

The genus name Lathraea derives from the ancient greek λαθραῖος (lathraîos), meaning "clandestine", [1] which is a reference to the fact that it is inconspicuous until it flowers. [2]

Phylogeny

The phylogeny of the genera of Rhinantheae has been explored using molecular characters. [3] [4] Lathraea is the sister genus to Rhinanthus , and then to Rhynchocorys . 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.

<span class="mw-page-title-main">Orobanchaceae</span> Family of flowering plants known as broomrapes

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.

<i>Boschniakia rossica</i> Species of plant

Boschniakia rossica, commonly known as the northern groundcone, is a holoparasitic plant that lives in the northern latitudes of the northern hemisphere. In the Pacific Northwest Temperate Rainforest, it does not grow south of Prince of Wales Island, beyond that boundary is the Vancouver groundcone habitat. It does not contain chlorophyll, so it must be parasitic to obtain nutrients. It specializes on Alnus species, but can parasitize off of other trees and shrubs such as on Betula (birch), Salix (willow), Vaccinium (blueberry), Picea (spruce), and Chamaedaphne. This organism is likely to be found at mid elevations alongside rivers and streams, where moisture is abundant. This species propagates itself through water flow. In some places bears are known to have eaten the starchy roots, or tubers, of this plant.

Orobanche hederae, the ivy broomrape, is, like other members of the genus Orobanche, a parasitic plant without chlorophyll, and thus totally dependent on its host, which is ivy.
