U. antennifera & U. quinquedentata in situ

[Siggi_Hartmeyer]

Near Beverley Springs (Australian Kimberley), we were able to film Utricularia antennifera in situ. The plants possess two antenna-like filaments at the otherwise inconspicuous flowers. According to Prof. W. Barthlott (University Bonn), that is probably a form of Mullerian mimicry: The flowers mimic a female insect to attract the male partners for pollination. Directly beside grows one of the smallest bladderworts. With a size of only two millimeters, the white flowers of U. quinquedentata are quite hard to find. We fished out these 1995 shots of rare Utricularia from our archive and remastered them for bladderwort enthusiasts.
