Abstract:

<p>Carex reznicekii is described as new from mesic to dry-mesic forests of Alabama, Arkansas, Connecticut, Delaware, District of Columbia, Georgia, Kentucky, Maryland, Mississippi, Missouri, New Jersey, New York, North Carolina, Pennsylvania, Rhode Island, South Carolina, Tennessee, and Virginia. Previously, C. reznicekii had mostly been misidentified as either G umbellata or C. nigromarginata. It is distinguished from these species as well as other members of section Acrocystis by a combination of lack of basal spikes, short culms, narrow leaves, and only slightly red pistillate scales. A key to the 19 taxa of section Acrocystis that occur in eastern North America is provided.

Previamente, G reznicekii, hab&iacute;a estado en su mayor parte mal interpretada como G umbellata o C. nigromarginata. Se distingue de estas especies as&iacute; como de otros miembros de la secci&oacute;n Acrocystis por la combinaci&oacute;n de carencia de espiga basal, c&uacute;lmenes cortos, hojas estrechas, y escamas femeninas s&oacute;lo levemente rojas. Se proporciona una clave para los 19 taxa de la secci&oacute;n Acrocystis que ocurren en el este de Norteam&eacute;rica.</p>
