The red disa is pollinated solely by the mountain pride butterfly, Meneris tulbaghia, and it is the abundance of this butterfly that dictates the success of the red disa in different habitats. Those plants growing in a rocky gorge are far more successful than those in an open valley, as the mountain pride butterfly prefers rocky, sheltered habitats (7). Red disas are evergreen plants but bear flowers only during the summer months, from December to March, with a peak flowering period in mid-February (5). Flowers of the red disa produce nectar to tempt the mountain pride butterfly to feed, and when the butterfly drinks from the long, tubular nectaries that store the nectar, pollen is deposited on their feet, facilitating pollination (8). The seed of the red disa is a relatively large balloon-shaped structure; a shape which is thought to have evolved to be suited to dispersal by water (9), perfectly adapted to their stream-side habitat.
