Utricularia humboldtii
A spectacular bladderwort from the Guiana Highlands of Venezuela, Guyana and Brazil, with the largest flowers in the genus, probably its largest traps too, and large, rounded leaves. It usually lives in the water-filled leaf tanks of Brocchinia and Orectanthe bromeliads, sending out upright stolons that find neighbouring tanks. It also grows as an epiphyte on tree trunks, in shallow water and in wet soil in open savanna. It wants cool-to-intermediate highland conditions with constantly wet roots.
Where it grows wild
It is typically found in the tanks of large bromeliads (Brocchinia, Orectanthe) on tepui slopes and summits, and in open, wet savanna. It also grows in shallow water, in wet soil and on tree trunks. Its stolons grow up and over into nearby tanks to form new plants.
It grows mostly at 1,200-2,500 m, but has been found as low as 300 m.
