Pollinarium Morphology and Floral Rewards inBrazilian Maxillariinae (Orchidaceae)

Pollinarium morphology, floral rewards and generic boundaries in brazillian orchids

Sixty species from seven genera of the orchid subtribe Maxillariinae are examined by Singer and Koehler (pp. 39-51) with a view to distinguishing major clades. They employ morphological characteristics of pollinaria and biomechanics of pollination. These reveal a larger than expected diversity that is expected to help redefine and diagnose clades of the Maxillariinae.
