Desfont.&#8221; Por lo que es necesario lectotipificar aquí. Por prioridad, Dioscorea pubescens es el nombre publicado previamente para ser empleado, aunque D. pilosiuscula Bertero ex Spreng., ha sido el nombre tradicionalmente usado desde su descripción en 1825. Dioscorea pubescens es muy variable, principalmente en su pubescencia y en la forma y tamaño de las hojas a través de su intervalo de distribución, y es esta variabilidad la razón por la cual este taxón ha sido descrito bajo diferentes nombres, de los cuales 7 son sinonimizados aquí. También, de acuerdo con sugerencias y cambios en el Código Internacional de Nomenclatura Botánica, todos los taxones incluidos deben ser lectotipificados.]]></p></abstract>

Martin s.n. collections filed in FI and P citing only &#8220;V.f. in herb. Desfont.&#8221; So it is necessary to lectotypify herein. By priority, Dioscorea pubescens is the earliest published name to use, although D. pilosiuscula Bertero ex Spreng., has been a name traditionally used since its description in 1825. Dioscorea pubescens is very variable, principally in its pubescence and in the form and size of leaves throughout its distribution range, and this variability has been the reason for the taxon&#8217;s description under different names, 7 of which are synonymized herein. Also according to new suggestions and changes in the International Code of Botanic Nomenclature, all of the taxa included in here should be lectotypified.]]></p></abstract>
