Are Margyricarpus and Lathraea both plants?
Lathraea 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.
Lagynias Lagynias was a genus of flowering plants in the Rubiaceae family but is no longer recognized. In 2005, it was sunk into synonymy with "Vangueria", based on a phylogenetic study of DNA sequences.
