Abolboda ciliata

Abolboda ciliata is a perennial herb in the family Xyridaceae, order Poales. The specific epithet ciliata means fringed with cilia or hairs, indicating that some structure of this plant, most likely the leaf margins, bracts, or perianth parts, bears a fringe of fine hairs. Ciliation is a taxonomically useful character in Xyridaceae, helping to distinguish species within genera such as Abolboda and Xyris that can otherwise appear morphologically similar. This genus is endemic to the Neotropics and concentrated in the Guiana Highlands region of northern South America, one of the world's most remarkable centres of plant endemism. Abolboda ciliata grows in the open, waterlogged, nutrient-poor habitats characteristic of the tepui ecosystem, including summit heathlands, rocky outcrops, and seasonally flooded savannas on ancient sandstone substrates. The family Xyridaceae is defined by its rush-like vegetative form, basal leaf rosettes or tufts, scape-borne terminal inflorescences, and three-petalled flowers with yellow, white, or blue corollas that open briefly each day. In Abolboda, the flowers are generally blue or violet. Pollination is by bees, and the small capsular fruits release numerous seeds dispersed by wind or water. The tepui flora, of which Abolboda ciliata forms a part, is of extraordinary scientific significance, representing the remnants of an ancient flora isolated on sky islands for millions of years, resulting in spectacularly high levels of endemism comparable to oceanic islands.
