NOMENCLATURE OFINDIAN SPECIES OF OXYTENANTHERA MUNRO1 H.B. Naithani2 The genus Oxytenanthera was described by species while the rest ofthe Asiatic species placed Munroin 1868.Holttum(1956)pointedoutthatthis underthis genusbelongeitherto Gigantochloa or genus is in fact monotypic with Oxytenanthera Dendrocalamus. This view has been supported by abyssinica (A. Rich.) Munro, a nativeAfrican type Clayton and Renvoize (1986) and Widjaja (1987) also.HoweverwhileworkingonthebamboosofSri Accepted September1990.
