Gigantochloa  

Bambusoideae. -- Much progress is being made in the understanding of bamboo phylogeny, largely due to the efforts of the BPG (Bamboo Phylogeny Group), a collaboration of 20 bamboo specialists from 11 countries, working on the first widely sampled data-rich phylogeny estimation for bamboos (Clark 2008; Kelchner & Clark 2008). Early phylogenetic study on the bamboos (Judziewicz et al., 1999) has them as being monophyletic, with two main lineages - herbaceous bamboos (Olyreae) and woody bamboos (Bambuseae).
