Nuevas especies de viguiera (Compositae, Heliantheae) del estado de Durango, México Jerzy Rzedowski M. Socorro González Elizondo Martha González Elizondo Biología Viguiera oligantha y V. inegii se describen como nuevas especies y se ilustran. Ambas son arbustos canescentes que se encuentran en forma simpátrica, endémicos del noreste del estado de Durango. La primera representa una condición poco usual en el género debido a sus cabezuelasnotoriamente reducidas, con 1 ó 2 flores del disco y 0 a 2 flores liguladas. Viguiera oligantha y V. inegii parecen ser especies hermanas posiblemente relacionadas con V. greggii (A. Gray) S. F. Blake, dela que difieren en tener hojas predominantemente alternas con nervaduras impresas, así como cabezuelas y flores más pequeñas. Ambas especies son afines a los componentes de la serie Brevifoliae, aunque para integrar en ella a V. oligantha es preciso ampliar la circunscripción del grupo. Se presenta una clave para la identificación de las especies que conforman la serie Brevifoliae en su carácter enmendado y se incluye una lista de materiales de herbario revisados de los restantescomponentes de esa serie. 2000 artículo científico 0187-7151 https://www.redalyc.org/articulo.oa?id=57405304 es http://www.redalyc.org/revista.oa?id=574 Acta Botanica Mexicana application/pdf Instituto de Ecología, A.C.
