- Pollination biology of Habenaria parviflora (Orchidaceae: Habenariinae) in southeastern Brazil Rodrigo B. Singer Biología Moths flies Crane Orchids Habenaria The pollination biology of Habenaria parviflora (Orchidaceae: Habenariinae) was studied inPicinguaba, São Paulo State, southeastern Brazil in order to broaden our knowledge on the pollinationbiology and functional morphology of this terrestrial orchid genus. Plants are self-compatible butpollinator-dependent. The recorded pollinators were crane-fly (Diptera: Tipulidae) females and pyralidmoths (Lepidoptera: Pyralidae). The pollination mechanism is the same regardless of the kind ofpollinator: the pollinaria are fixed on the insect proboscis through the glove-like viscidium and removedwhen the insects leave the flowers. A pollinarium-carrying insect visiting another flower will brush thestigmatic surfaces and leave clumps of massulae, thus effecting pollination. This mode of pollinariumfixation is, as far as we know, reported for the first time for the genus Habenaria and is a clearconsequence of viscidiums morphology. The involute, glove-like viscidium is a unique flower featureamong neotropical Habenaria species. Flower features promoting cross-pollination are brieflydiscussed. This is also the first report of orchid pollination by crane-flies (Tipulidae) in the neotropics 2001 artículo científico 0011-6793 https://www.redalyc.org/articulo.oa?id=66939402 en http://www.redalyc.org/revista.oa?id=669 Darwiniana application/pdf Instituto de Botánica Darwinion Darwiniana (Argentina) Num.3-4 Vol.39
