A wheat ribosomal DNA probe was used to determine the number of rDNA-carrying chromosomes in 2 Erianthus sect. Ripidium species using FISH (fluorescent in situ hybridisation) and non-fluorescent ISH. Two and four ribosomal DNA sites were revealed in E. elephantinus (2n = 20) and E. procerus (2n = 40), respectively. This result, together with previously published data showing 6 rDNA-carrying chromosomes in E. arundinaceus (2n = 60), confirms a possible basic chromosome number of x = 10 in Erianthus sect. Ripidium.
