There are six species of Heliamphora on the tepuis. Five of the species, like H. minor (shown), tend to have short stems, but one, H. tatei, tends to climb or lean on other plants and reaches 4 m in height. According to DNA data, Heliamphora is most like the ancestor of the family Sarraceniaceae. The flowers are recurved, as in Darlingtonia and Sarracenia. Recurved flowers have been claimed to be an adaptation for keeping rain from collecting in flowers, and thus pollination could occur even during rainy periods.
