Angraecum cadetii and its pollinator Glomeremus sp. (A) Flower of A. cadetii with pollinia exposed (anther cap removed). A pollinarium (Po) consists of two hard, pale-yellow pollinia, both of unusual size and shape relative to those of related species; they are larger, triangular, and flat; both pollinia are removed simultaneously by pollinators. The fleshy lip (Li) is reduced relative to related species and forms a short conical spur (Sp) that has wide entrance with a large amount of nectar. (B) Glomeremus sp. Note the absence of wings. (C and D) Glomeremus sp. foraging on A. cadetii flowers and carrying pollinaria (Po) on its head (pictures from video captured with the night-shot option).
