A review of the generic taxonomy of the genus gigantochloa, oxytenanthera and pseudoxytenanthera from Vietnam
Keywords:
Gigantochloa, Oxytenanther, Pseudoxytenanth, VietnameseAbstract
The genus Gigantochloa Kurz ex Munro, Oxytenanthera Munro and
Pseudoxytenanthera Soderstrom & Ellis from Vietnam are thoroughly studied and revised. Based on collected specimens, specimens in some herbaria, compared with the major modern systems of classification of the wood bamboos, the authors suggests that Gigantochloa should include Oxytenanthera, Pseudoxytenanthera. We also suggested
the diagnostic characters were mid-culm branch complement with a dominant primary branch and several small secondary branches, 1-5 perfect flowers, an imperfect or not an imperfect terminal floret, palea 2-keeled or convex, filaments always fused into a tube. And based on the structure of the pseudospikelets which are a perfect terminal
floret and an imperfect terminal floret, two subgenera, subgen. Heterofloreta and Monofloreta were established
