A new species, new synonyms, typifications, and a name correction in Neomarica from Brazil (Trimezieae, Iridaceae)

As the result of a taxonomic project on Neomarica , we describe and illustrate a new species, Neomarica kollmannii , and propose ten new synonyms for six species of the genus: N. altivallis , N. glauca , N. caerulea , N. longifolia, N. imbricata and N. sabinei . We also designate lectotypes for four accepted species and five new synonyms, and neotypes for three new synonyms. Comments on the synonyms and typifications are provided. Lastly, we indicate the correct spelling of N. sabinei (previously known as N. sabini , as cited in several indexes).
