New records of Digitaria filiformis var. laeviglumis (Paniceae, Panicoideae, Poaceae) for the Flora del Bajío and Durango, Mexico
Background and Aims: Since its publication in 1920, Digitaria filiformis var. laeviglumis had been considered as an endangered taxon endemic to New Hampshire, USA. However, a recent inventory of the grasses of Mexico showed that it also occurs outside its type locality. New findings for the ongoing...

| description | Background and Aims: Since its publication in 1920, Digitaria filiformis var. laeviglumis had been considered as an endangered taxon endemic to New Hampshire, USA. However, a recent inventory of the grasses of Mexico showed that it also occurs outside its type locality. New findings for the ongoing project Flora del Bajío have yielded additional new records. The objective of this work is to report this taxon from the Mexican states of Michoacán and Durango, increasing the number of known localities of Digitaria filiformis var. laeviglumis.Methods: Online databases and herbaria were reviewed. Botanical herbarium specimens were collected in the state of Michoacán.Key results: Digitaria filiformis var. laeviglumis is reported as new for the Flora del Bajío in the state of Michoacán, as well as from a herbarium specimen from Durango which has both var. laeviglumis and var. filiformis mounted on the same sheet and that was misplaced among other specimens.Conclusions: With the addition of this variety, the number of taxa in the subfamily Panicoideae increases for the Flora del Bajío and the state Durango. With these findings there are more intermediate localities between the northern and southern range for this variety. |

Antecedentes y objetivos: Desde su publicación en 1920, Digitaria filiformis var. laeviglumis fue considerado como un taxon endémico y en peligro en Nueva Hampshire, EUA. Sin embargo, un reciente inventario de las gramíneas de México mostró que también ocurre fuera de su localidad tipo. Nuevos hallazgos dentro del proyecto Flora del Bajío representan nuevas adiciones. El objetivo de este trabajo es reportar registros nuevos recientemente encontrados de Michoacán y Durango, incrementando el número de localidades de D. filiformis var. laeviglumis.Métodos: Se revisaron bases de datos en línea y herbarios. Se colectaron especímenes botánicos en el estado de Michoacán.Resultados clave: Se reporta Digitaria filiformis var. laeviglumis como nuevo para la Flora del Bajío en Michoacán, además de un ejemplar de Durango que tiene ambas variedades laeviglumis y filiformis montadas en el mismo ejemplar y que estaba mal colocado entre otros especímenes.Conclusiones: Con la adición de esta variedad el número de taxa de la subfamilia Panicoideae se incrementa para la Flora del Bajío y el estado de Durango. Con estos hallazgos aumentan el número de localidades intermedias entre el intervalo norte y sur de esta variedad.
