Phosphorae radians, named for its radiant light-bearing flowers, is a bioluminescent herbaceous species with complex inflorescences featuring elongated, ruffled petals transitioning from vibrant orange centrally to lilac and violet edges. Translucent glandular dots on petals likely aid light diffusion. The dense central capitulum contains tubular florets with anthers and stigmas emitting an amber glow. Leaves, presumably ovate and basal, support a 30-50 cm tall, sturdy yet flexible stem (50-150 g). Bioluminescence occurs in the blue-green spectrum (450-495 nm) via luciferin-luciferase reactions in specialized epidermal cells of petals and reproductive organs, producing gentle light visible in dim tropical understory conditions. Native to warm (20-30°C), humid forests, it attracts nocturnal moths and bioluminescent beetles through synchronized luminescent signals and petal movement. Taxonomically, it belongs to Herbaceous Scintillans in genus Phosphorae, with 10 glowing species. Vulnerable status necessitates conservation.
