Abstract:

Phylogenetic relationships among core taxa of the paleotropical bamboo clade placed in subtribe Bambusinae, comprising Bambusa s.l. (including Bambusa s.str. and its subgenera Leleba and Lingnania) and its allies (including Dendrocalamopsis, Dendrocalamus, Gigantochloa, Melocalamus and Thyrsostachys), and with Neosinocalamus and Oxytenanthera, were examined by separate and combined cladistic analyses of the nuclear GBSSI gene and plastid psbA-trnH, rpl32-trnL and rps16 intron sequences using maximum parsimony and Bayesian inference analyses. The taxa were strongly supported as a monophyletic group, which represents subtribe Bambusinae. Melocalamus and Thyrsostachys were confirmed as good genera. In the combined analysis, Bambusa s.l. and Dendrocalamopsis formed one of two clades with reasonable support, and Dendrocalamus clustered with Gigantochloa, Neosinocalamus and Oxytenanthera in the other. The topology also identified several taxa that were misplaced in Bambusa or Dendrocalamus. Sinocalamus (currently a subgenus of Dendrocalamus) appeared to be heterogeneous and contained taxa allied to Bambusa or Dendrocalamus. Except for Oxytenanthera, the alliance of Bambusa and allies appeared well characterized by a broadly conical, solid and typically hairy ovary summit. The taxonomic significance of rachilla and floret characters, considered useful in distinguishing subsets of genera, remains uncertain.
