Casatia
Casatia is a genus of flowering plants belonging to the family Burmanniaceae. These are small, myco-heterotrophic herbs, meaning they obtain nutrients from fungi rather than through photosynthesis.
Description
Casatia plants are typically characterized by their slender, thread-like stems and small size. They lack chlorophyll and therefore appear pale or translucent white, sometimes tinged with pink or yellow. The leaves are reduced to scales, and the flowers are small and inconspicuous. They are often found in damp, shaded environments within forests.
Distribution
Species within the Casatia genus are primarily found in tropical regions of Asia, particularly Southeast Asia and the Indian subcontinent. Their specific distribution varies depending on the species.
Ecology
As myco-heterotrophs, Casatia plants are entirely dependent on symbiotic relationships with fungi for their carbon and nutrients. They establish connections with fungal networks within the soil, tapping into resources obtained through the fungus's association with other plants or decomposing organic matter. This mode of nutrition makes them highly specialized and vulnerable to habitat disturbance.
Taxonomy
The taxonomic classification of Casatia has seen revisions over time. The genus belongs to the family Burmanniaceae. The exact number of species within the genus is subject to change as new species are discovered and existing classifications are refined.
