Bioluminis Floraeternum, meaning 'eternal luminous flower,' exhibits enduring bioluminescence within the Nereid Petalus cluster. It features multilayered, translucent petals (15-30 cm) with a gradient from blue-tinted bases to orange, ruffled, pollen-dense margins, mimicking aquatic undulation despite a terrestrial habitat. Semi-transparent leaves with fine venation and a slender, sturdy stem support its 15-50 g mass. Emitting 420-490 nm light via photocytes on petal surfaces, its chemiluminescence involves luciferin-like compounds and structural refraction. Native to tropical rainforest canopies at 10-20°C, it uses petal movements to attract nocturnal pollinators like moths and bioluminescent beetles. Endangered, conservation targets its ecological niche and pollination symbiosis.
