Lacandonia schismatica is a species of mycoheterotrophic plant in the Triuridaceae (although some taxonomists place the genus in a separate family; the Lacandonaceae.).

[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.

Gerrit Davidse and Esteban Martínez noted in 1990 how the plants are "extremely localized and highly endangered" due to encroaching habitat conversion to cattle pasture.

They also explain that the species is difficult to cultivate and therefore they encourage other scientists to study this unique organism's biology before it can no longer be found in the wild.
