Heliamphora collina
Heliamphora collina is a species of marsh pitcher plant known from the Los Testigos and Ptari-tepui massifs in Venezuela[1] It grows at elevations of 1700–1825 m.[1] The first specimens of the species were first collected by Otto Huber, Julian Steyermark and others in 1986 and originally classified as Heliamphora heterodoxa. After additional in-situ studies it was described as a new species in 2011 by Andreas Wistuba, Joachim Nerz, Stewart McPherson and Andreas Fleischmann.[1] First believed to be endemic to the common foothills of the four tepuis of the Los Testigos chain,[1] observations of plants possibly matching the description of Heliamphora collina had been made from a distance during helicopter expeditions to the summit of Ptari-tepui in 2009 and 2017. Specimens of Heliamphora collina were later confirmed to occur on the southwestern slopes of Ptari-tepui by Mateusz Wrazidlo during an expedition to the massif in 2018.[2] References
