tantalilla

Tantalilla is a genus of small South American plants belonging to the family Asteraceae. These plants are typically found in the high-altitude grasslands and páramo ecosystems of the Andes mountains, particularly in Peru, Bolivia, and Ecuador. The genus name "Tantalilla" is thought to be a diminutive of the Greek god Tantalus, possibly alluding to the plants' elusive nature or their preference for inaccessible habitats.

The species within Tantalilla are generally herbaceous perennials, characterized by their low-growing habit and often rosette-forming leaves. The leaves are typically narrow and linear or lanceolate, and can be either smooth or hairy. The flowers are small and daisy-like, with the ray florets often being white, pink, or purple, and the disc florets typically yellow. These flowers are borne on slender stems, which can be either erect or somewhat spreading.

Tantalilla species are adapted to harsh alpine conditions, tolerating cold temperatures, strong winds, and intense solar radiation. Their exact ecological roles are still under study, but like many Asteraceae, they likely contribute to pollination networks and soil stabilization in their native environments. Due to their specialized habitat requirements, some Tantalilla species may be vulnerable to environmental changes, such as climate shifts or habitat degradation. Research into the genus continues to document its diversity and conservation status.
