Obscuraflora Radiancea, named from Latin for 'dark flower,' is a bioluminescent species in the Luminous Petalaceae family. It grows 10–25 cm tall, weighing 15–50 g. Flowers have densely packed, ruffled petals arranged spirally, exhibiting a gradient from deep emerald green with speckles to fiery crimson at the core. Leaves are elongated, undulating with a turquoise sheen, found in moist habitats. The sturdy, flexible stem supports nocturnal swaying. Bioluminescence emits a cool blue-green glow (450–495 nm) along petal edges and reproductive parts via epidermal luciferin-luciferase reactions. Native to tropical wetland forests at 20–30°C and high humidity, it facilitates moth and nocturnal insect pollination. This unique species is endangered due to habitat loss, highlighting conservation needs.
