Trenia

Trenia is a genus of plants in the family Asteraceae, commonly known as the tribe Astereae. These plants are native to various parts of the world, with a significant presence in temperate regions. The genus contains several species, each with distinct characteristics and geographical distributions.

The morphology of Trenia species can vary, but they generally exhibit herbaceous growth habits, often with alternate leaves. Their flowers are typically borne in capitula, or flower heads, which are characteristic of the Asteraceae family. These flower heads are composed of numerous small florets, often with ray florets surrounding central disc florets, giving them a daisy-like appearance. The color of the flowers can range from white and yellow to shades of blue and purple, depending on the species.

Trenia plants are important components of their native ecosystems, providing habitat and food sources for various insects, including pollinators. Some species have also found uses in traditional medicine or as ornamental plants in horticulture. The exact ecological roles and ethnobotanical uses can differ significantly between the various species within the genus. Further research continues to explore the biodiversity and potential applications of Trenia.
