Ovule and seed development of Lacandonia schismatica (Lacandoniaceae).

Lacandonia is a genus of mycoheterotrophic plants in the Triuridaceaewith very unusual inverted floral morphology. Botanical Journal of the Linnean Society4: Climate change and habitat destruction could permanently alter the conditions so that this plant can no longer exist in the wild.

This suggests that the inversion evolved before the Lacandonia schismatica lineage diverged. It has two known species: The chromosome number of Lacandonia schismatica Lacandoniaceae. Pollen development and fertilization in Lacandonia schismatica Lacandoniaceae.

To figure out why L. It is not quite clear how this system could have evolved in this species.

It is also possible that chromosomal repatterning, also known as chromosomal rearrangement, was the origin of this species. From Wikipedia, the free encyclopedia. Lacandonia is a mycoheterotrophic plant that contains no chlorophyll and has the unusual characteristic of inverted positions of the male androecium and female gynoecium floral parts, something that had not been seen in any other plants with the occasional exception of some individuals of the related Triuris brevistylis.

How this inverted position of the androecium and lacandoni evolved is unknown, but some studies have posed hypotheses. Views Read Edit View history.

Inside-out flowers characteristic of Lacandonia schismatica evolved at least before its divergence from a closely related taxon, Triuris brevistylis. The sole member of its genus, Lacandonia schismatica grows in only a few locations in the Lancandon Jungle of southeastern Mexico.

It was discovered that every once in a while, a closely related species known as Triuris brevistylis will sometimes produce flowers with a similar inverted morphology.
