Heliamphora
Heliamphora, commonly known as sun pitchers or marsh pitcher plants, is a genus of carnivorous plants native to the remote, high-altitude tepuis of Venezuela, Guyana, and Brazil. These plants feature tubular traps formed from rolled leaves with fused edges, designed to lure and capture insects using nectar secreted from a small spoon-like structure at the top of each pitcher.
Unlike many other pitcher plants, Heliamphora lacks a lid; instead, it has evolved drainage holes or slits to prevent rainwater overflow, maintaining optimal trap conditions. The inner surfaces of the pitchers are lined with downward-pointing hairs that guide prey into the digestive zone. Some species, like Heliamphora tatei, produce their own digestive enzymes, while others rely on symbiotic bacteria.
With over 20 known species, Heliamphora exhibits remarkable diversity and adaptation to its harsh, nutrient-poor environment, making it a subject of interest in evolutionary biology and a prized plant among carnivorous plant enthusiasts
