Data on pollination ecology of Araceae are still scarce and most concern species belonging to the subfamily Aroideae (García-Robledo et al. 2004, Gibernau 2003, Ivancic et al. 2004, 2005; Maia & Schlindwein 2006). In this subfamily, inflorescences consist of unisexual flowers: female flowers are located in the lower portion and the male flowers are in the upper portion of the inflorescence (Mayo et al. 1997). In the documented neotropical Aroideae, pollinators are nocturnal beetles and pollination mechanisms take place within a floral chamber during a short flowering cycle (generally 24–48 h) with floral rewards (sterile flowers rich in proteins and/or lipids) for the beetle pollinators, the secretion of resin to secure pollen on the pollinator, and the production of heat and odours (Chouteau et al. 2007, García-Robledo et al. 2004, Gibernau & Barabé 2002, Gibernau et al. 1999, 2000, 2003; Maia & Schlindwein 2006, Young 1986).

Most Diuris species possess flowers of pea-like form and colour, and occur in association with flowering peas of the tribe Mirbeliae. Previous studies of the pollination of Diuris maculata sensu lato have found evidence for guild mimicry of pea flowers. The flowers of Diuris alba are also pea-like in form but not in colour, and this species is frequently found in habitats where peas are uncommon or absent. We investigated the pollination of Diuris alba, which we expected may have a distinct pollination system at Lake Munmorah, New South Wales. Many Diuris species lack floral rewards, but D. alba produced a small amount of nectar. Flower visitors, and hence putative pollinators, were mainly female Exoneura bees, but also the wasps Eurys pulcher and a Paralastor species. Reproductive success of D. alba, both in woodland containing abundant Dillwynia retorta and in heathland where this pea was absent, was higher than in the previously studied D. maculata s.l. We suggest that the pollination of D. alba is more generalised than that found in the legume guild mimic D. maculata s.l. Although its flowers may display structural similarity to pea flowers, other characteristics suggest that its pollination system has diverged from a presumed pea-mimicry ancestral condition.
