Socorro González Elizondo Biología Mexico Durango taxonomy Cyperaceae Eleocharis Eleocharis reznicekii (Cyperaceae, subg. Eleocharis, series Eleocharis), is describedand illustrated. It is morphologically intermediate between E. densa and two species ofEleocharis subseries Eleocharis (E. macrostachya and E. palustris). The new species differsin a combination of characters including conspicuously compressed culms (3 to over 5 timeswider than thick) and stylopodium sessile on a thin annular base. Eleocharis reznicekiidiffers additionally from E. densa by having relatively lax spikelets, mostly bifid styles, andachenes almost smooth at 30x. From E. macrostachya and E. palustris it is distinguished inits oblong to linear-oblong spikelets, the proximal floral scale clasping only 1/3 to slightlymore than 1/2 of the culm, and the proximal plus 1-2(3) subproximal scales without a flower.Eleocharis reznicekii is known only from the state of Durango, in the Mexican high plateauand piedmont of the Sierra Madre Occidental. 2007 artículo científico 0187-7151 https://www.redalyc.org/articulo.oa?id=57408103 en http://www.redalyc.org/revista.oa?id=574 Acta Botanica Mexicana application/pdf Instituto de Ecología, A.C.
