title: Phylogenetic analysis of Bambusa (Poaceae: Bambusoideae) based on internal transcribed spacer sequences of nuclear ribosomal DNA.
abstract: Phylogenetic analyses of Bambusa species were performed using internal transcribed spacer sequences of nuclear ribosomal DNA. The 21 species sampled included members of Bambusa (sensu stricto), Dendrocalamopsis, Dendrocalamus, Guadua, Leleba, and Lingnania. Arundinaria gigantea was used as an outgroup. Using the maximum parsimony method with PAUP*, gaps were treated as missing states or new states. Parsimonious analysis revealed that Dendrocalamus latiflorus was closely related to the members of Dendrocalamopsis. Dendrocalamus membranaceus was a sister species to Dendrocalamus strictus. Three Dendrocalamus species were closely related to and nested in a polyphyletic Bambusa. Bambusa subaequalis was a sister species to B. multiplex, B. emeiensis to B. chungii, B. contracta to B. hainanensis, and B. flexuosa was a sister species to B. sinospinosa, B. tuldoides, B. surrecta, B. intermedia, and B. valida group, which raised doubts about the monophyly of the subgenera Bambusa (sensu stricto), Dendrocalamopsis, Leleba, and Lingnania under the genus Bambusa.
