The rarity of Atuna indica, an endemic and endangered tropical tree species of the Western Ghats, India has been analysed in this study. The phenology, floral biology, including pollen–ovule ratio, pollinators, fruit development and biotic interactions in natural dynamics were studied. Extreme reduction in the number of flowering individuals, microhabitat conditions, low fruit set, seed infestation and fruit predation were identified as the factors leading to rarity of the species in situ.
