[3] Owing to the preathesis cleistogamy, a form of autogamy (self-pollination), the known population of L. schismatica lacks genetic variability and has a high incidence of homozygosity.
[4] Lacandonia is a genus of mycoheterotrophic plants in the Triuridaceae, with very unusual inverted floral morphology.
[11] The difficulty expressed in placing the species in the proper family is due to the unique floral morphology.
This discovery led the authors of the study to conclude that the inverted floral morphology evolved before L. schismatica and T. brevistylis diverged.
Isolated populations during the Quaternary Period (around five million years ago), when temperatures in the Lacandon lowland rainforest were six to eight °C (10.8 to 14.4 °F) cooler than today.
