Tyleria

Tyleria is a genus of flowering plants belonging to the family Ochnaceae. These plants are characterized as shrubs or small trees, primarily found in the Guiana Shield region of South America, notably in Guyana, Suriname, and Venezuela.

Tyleria species are known for their coriaceous (leathery) leaves and their relatively small, often white or cream-colored, flowers. The fruit are typically small drupes.

The taxonomic classification and evolutionary relationships within the Ochnaceae family, including Tyleria, have been subject to ongoing research and refinement. Several species were originally classified within the genus Adenanthe before being reassigned to Tyleria.

Currently, recognized species within the genus Tyleria include, but may not be limited to: Tyleria grandiflora, Tyleria phelpsiana, and Tyleria silvana.

The ecological role of Tyleria plants is related to their presence in the rainforest and tepui ecosystems of the Guiana Shield. They contribute to the biodiversity of these regions and serve as a food source or habitat for various local fauna.
