Alstroemeria maranhensis (Alstroemeriaceae): A new species from the Cerrado of Brazil

Abstract We describe, discuss and illustrate Alstroemeria maranhensis, a new species from the Cerrado domain in south-central Maranhão State, Brazil. We also provide a distribution map, a photographic plate and taxonomic comments. The new species is morphologically similar to A. viridiflora, though differs by having predominantly white flowers (vs. reddish or yellowish in A. viridiflora), falcate lower outer tepals (vs. not falcate) and obovate-spatulate lower inner tepal with attenuate and flat base (vs. spatulate without attenuate and/or flat base).
