Utricularia pusilla
A tiny annual terrestrial bladderwort in section Setiscapella, widespread from Mexico and the Caribbean to Argentina. It grows in waterlogged soil in wet savannas, flooded grasslands and seepages, trapping microscopic prey with bladders in the wet substrate and sending up slender, thread-like stalks of small yellow flowers. In cultivation treat it as a short-lived, self-seeding plant for a permanently wet tray.
Where it grows wild
Herbarium labels describe wetlands with very wet soil, mats of wetland plants, dense seasonally flooded grassland without trees and the edges of premontane rain forest. It favours open, sunny, constantly wet sandy or peaty ground, much of it seasonally inundated.
Records run from sea level to about 1900 m; half lie below about 325 m, so it is mainly a lowland plant.
