Floralumina Caelesti, named for its glowing, celestial appearance, is a bioluminescent plant of the genus Corallium within the Celestialia cluster. It features translucent, ruffled, radially symmetrical petals with fine venation highlighted by bioluminescent pigmentation in pale blues to peachy oranges. Tiny filamentous reproductive structures concentrate at petal margins. The flexible, filament-like stem enables undulating movement in marine caves (5-15°C). Luminescence at 470-530nm emits a blue-green glow from photoproteins in epidermal cells, triggered by environmental stimuli. Rare and small (10-25 cm, 0-15 g), it sustains nocturnal marine pollinators via hydrophilous cross-pollination, representing an evolutionary link between floral biology and oceanic darkness within its 10-species group.
