Phosphoralis Etherealis, from Latin 'phosphorus' (light-bearer) and 'etherealis' (ethereal), is a rare bioluminescent flowering species in the Illuminaetherea Petalens cluster. It features translucent, wavy petals with radial symmetry, luminescent blue veins (450-495nm), and a warm amber glowing corolla near reproductive organs. Its thin, undulating leaves enable aquatic movement, adapted to submerged growth in tropical caves at 0-10ºC. Growing 15-30 cm tall and weighing 10-50 grams, its stem supports petals and facilitates nutrient transport in low-light, humid conditions. The genus contains 10 bioluminescent underwater species. Bioluminescence, from luciferase enzymatic reactions in epidermal cells, emits steady blue light attracting nocturnal cave pollinators like bioluminescent beetles and moth analogs, signaling nectar and enhancing reproduction. This stable species supports nocturnal pollinator networks and cave biodiversity.
