Descrizione
È una piccola specie erbacea priva di clorofilla e micoeterotrofica, cioè che intrattiene relazioni saprofitiche con alcuni funghi.[2]
Il fiore ha caratteristiche uniche nel mondo vegetale, con il gineceo che circonda l'androceo.[3][4]

Lacandonia schismatica is a species of mycoheterotrophic plant in the Triuridaceae (although some taxonomists place the genus in a separate family; the Lacandonaceae.). It is endemic to Lacandon Jungle in the State of Chiapas in southern Mexico.[1] It is known from very few populations and is considered endangered by the researchers who investigate this species.[2] It, and its recently discovered relation Lacandonia braziliana, are the only known flowering plants which in its natural population has a spatial inversion of the reproductive floral whorls (ie stamens and carpels): the 2 to 4 stamens are positioned centrally within the flower, and the 60 to 80 carpels arranged in a ring around them.[3] [4] Perhaps even more remarkable than the reversed positions of male and female parts is the unique mode of pollination. The pollin grain never leaves the anther, but sends the pollin tube backwards through the length of the stamen, across the receptacle and then into the pistil from below.[5]- [it] Lacandonia schismatica
