Utricularia steyermarkii

Utricularia steyermarkii is a small, probably perennial bladderwort endemic to the Guayana Highlands of Venezuela and the sole member of section Steyermarkia. It grows among mosses at the shaded, moist base of sandstone bluffs and ledges on tepuis around 1550-1850 m. Grow it like a highland tepui Utricularia: cool-intermediate temperatures, constant moisture, very high humidity and bright shade.

Where it grows wild

Terrestrial lithophyte in bryophyte mats at the shaded, moist foot of sandstone bluffs and ledges, near waterfalls and streams, and in savanna patches on tepui summits.

Herbarium records at about 1550-1850 m on Auyán-tepui, the Río Churún area, Gran Sabana, Cerro Aracamuni and the Neblina massif; an 880 m record on Neblina looks doubtful.
