Summary
The herbaceous bambusoid genus Olyra is revised. Four new South American species are described: Olyra amapana, O. latispicula, O. retrorsa, and O. tamanquareana. Three species of Olyra were found to differ significantly from the rest of the genus in possessing the following combination of characters: weak, scandent culms; filiform female spikelet pedicels; female spikelets that fall entire, have a pulvinate internode between the inflated glumes, and a stipitate anthecium; and a hilum that does not extend for the entire length of the caryopsis. The segregate genus Parodiolyra is established to accommodate these species, and the new combinations P. lateralis, P. luetzelburgii, and P. ramosissima are proposed. The new genus may share affinities with Raddiella and Diandrolyra rather than Olyra. Keys to the species in both genera are presented, as well as complete descriptions, field photographs, and distribution maps. Scanning electron microscope studies of the surface of the female anthecia yielded characters of taxonomic significance. These are illustrated and incorporated in the key. Two appendices account for all names that have been published in the genus Olyra.
