Abstract:
A comprehensive taxonomic revision of the genus Luziola (Poaceae: Oryzeae) is presented. Based on observations of herbarium material and living plants of the twelve previously recognized species of Luziola, we recognize nine species in the genus. The utility of specific taxonomic characters is also evaluated, with particular emphasis on inflorescence, lemma and palea characters. Detailed taxonomic descriptions are given for every species including phenological data, chromosome number and uses. Morphological and anatomical structures related to an aquatic habitat are also discussed. The names Luziola doelliana Prod. and Luziola leiocarpa Lindm. are lectotypified. Luziola caespitosa, L. subintegra and L. spruceana are illustrated.
