Utricularia spruceana
A tiny bladderwort from the lowland Amazon and Guiana Shield. It is anchored in wet sand or shallow water at lake and river margins and in white-sand campinas. It was once merged with U. resupinata but is now accepted as a separate species. Little is recorded about it, so grow it like other small, warm, sun-loving affixed aquatic bladderworts: wet sand, high light and constant warmth.
Where it grows wild
A small, affixed subaquatic or terrestrial bladderwort. Labels note it as a terrestrial herb at the lake margins of Lago Verde at Alter do Chão, near Santarém, around the mouths of blackwater creeks, and in a white-sand campina on the Rio Uneiuxi in the Rio Negro basin.
It is a lowland plant: the labelled elevations are 11–130 m, and Colombia's catalogue gives about 120 m.
