Utricularia humboldtii is a largeperennialcarnivorous plant that belongs to thegenusUtricularia.Peter Taylor lists it as either an "aquatic-epiphyte", a subaquatic or a terrestrial species.U. humboldtii isendemic toSouth America, where it is found inBrazil,Guyana, andVenezuela. It was originally published and described byRobert Hermann Schomburgk in 1840. It is usually found growing in the water-filled leaf axils of some species ofbromeliad, includingBrocchinia micrantha,B. tatei, andB. reducta and also plants in the genusOrectanthe. It also grows as anepiphyte on tree trunks or as a subaquatic or terrestrial species in shallow water or wet soil in open savanna. It is found mostly between altitudes of 1,200 m (3,937 ft) and 2,500 m (8,202 ft), though it has been found at altitudes as low as 300 m (984 ft). It has been collected in flower throughout every month of the year.[1]
U. humboldtii possess the largest flower of the genus and most likely also the largest bladder traps. As it usually lives within the water-filled leaf axils of bromeliads, it occasionally needs to search for new pools of water, so it sends out uprightstolons that find nearby bromeliads, descend into the water, and grow into a new plant.[1]
