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). However recent work (Clark 2008) indicates that the temperate woody bamboos are sister to a group of tropical woody bamboos and the Olyreae. An early detailed classificatory scheme of the woody bamboos (Dransfield & Widjaja 1995) consists of 9 subtribes, without evidence of it being based on any published phylogeny, although the existence of some of these subtribes is presented in the cladograms of Zhang & Clark (2000) and of Clark et al. (2007).
GrassWorld currently includes 112 genera and 1647 species within the Bambusoideae (Table 2). Of these 21 genera and 116 species belong to the herbaceous Olyreae and the remaining 90 genera and 1062 species to the woody Bambuseae. Many new genera have been described since Dransfield & Widjaja (1995) and, of them, 21 have not been designated to a subtribe. It appears that a number of these new genera have no phylogenetic basis but are described on the basis of phenetic differences from existing genera. The rationale for having them described at this stage of their knowledge is probably related to issues of conservation and having names for communication. The bamboos are unusual in this respect in that in many cases no flowering material is known and new species have been described solely from sterile material (Franklin 2008).
