A new record of Dinochloa malayana S.Dransf. (Poaceae, Bambusoideae) from central Sumatra, Indonesia, reveals the continuous distribution of Dinochloa in western Malesia

Abstract

We report a new record of Dinochloa malayana S.Dransf. (Poaceae, Bambusoideae) from Sumatra, Indonesia, specifically in Sumpur Kudus, Sijunjung, West Sumatra. This discovery expands the known western range of Dinochloa Buse in Malesia. On the mainland of Sumatra, this genus, represented by D. glabrescens Widjaja, was previously only reported from Lampung in the south. Dinochloa was once thought to have a disjunct distribution in western Malesia, limited to the Malay Peninsula and southern Sumatra. Our new data confirm the continuous distribution of Dinochloa throughout western Malesia.
