Pollination Biology of Myrrhinium atropurpureum (Myrtaceae): Sweet, Fleshy Petals Attract Frugivorous Birds
Myrrhinium atropurpureurn has unusual floral characteristics: sweet, juicy petals, long vivid stamens, and absence of nectar and odor. This uncommon syndrome is morphologically and anatomically described. Floral phenology is also described, and censuses of flower visitors are provided. The main pollinators are frugivorous passerine birds, which are attracted by the petals. This type of floral reward is vev uncommon and seems to be restricted, in South America, to Myrrhinium, &&a (Myrtaceae) and Calreohria (Scrophulariaceae). The possible origin of the pollination mechanism is discussed.
