Abstract

In the late 1950s, S!"#$% V&'"( provided evidence that tiny 0ies (Dipteras) act as regular pollinators of the trap 0owers of Ceropegia, Apocynaceae-Asclepiadoideae, (micromyiophily). 1ese studies laid the foundation for later, breathtaking discoveries, namely that 0owers of several non-related families have adapted to the pollination by another group of tiny 0ies: fungus gnats (Mycetophilidae, Sciaridae and relatives). In particular, V&'"( demonstrated that the respective plants (mainly dwellers of the dark, damp forest 0oor, with 0owers positioned within in or slightly above the forest litter) have obtained morphological and olfactory characters of fungi in the course of evolution. Such “fungus mimetes” represent a then undescribed ecological subcate-gory of the myiophilous 0oral syndrome. 1ey have evolved (at least) in four plant families: Aristolochiaceae (birthwort family), Araceae (aroids), Corsiaceae, and Orchidaceae (orchids). Perhaps the most spectacular examples are provided by Aristolochia arborea, with a perfect mushroom dummy placed at the entrance of the pitfall 0ower, and species of the orchid genus Dracula, in which the labellum imitates the head of a gilled mushroom.
