Abstract
<jats:italic>Cyperus prophyllatus</jats:italic>, an endangered new species of <jats:italic>Cyperus</jats:italic> (Cyperaceae) from an aquatic ecosystem of the Atlantic Forest, Espírito Santo State, southeastern Brazil, is described and illustrated. The spikelet morphology of <jats:italic>Cyperus prophyllatus</jats:italic> is unique among the c. 950 species of <jats:italic>Cyperus</jats:italic> in having both a conspicuous spikelet prophyll and a corky rachilla articulation, which remain persistent at the base of the spikelet after disarticulation. Our molecular phylogenetic data support the placement of <jats:italic>C</jats:italic>. <jats:italic>prophyllatus</jats:italic> in the C<jats:sub>3</jats:sub> <jats:italic>Cyperus</jats:italic> Grade and more precisely in the clade representing <jats:italic>Cyperus</jats:italic> sect. <jats:italic>Oxycaryum</jats:italic>, which also includes <jats:italic>C</jats:italic>. <jats:italic>blepharoleptos</jats:italic> and <jats:italic>C</jats:italic>. <jats:italic>gardneri</jats:italic>. Anatomical and (micro)morphological analyses corroborate the phylogenetic results, provide a better understanding of ecology and taxonomy, as well as reveal compatibility of structures with survival and dispersion in aquatic environments. A distribution map, table with distinctive characters of allied species, and conservation status are made available.</jats:p>
