The genus Phyllostachys (Poaceae, Bambusoideae) in the Arkansas (U.S.A.) flora

Le résumé fourni par la source

Previously, the genus Phyllostachys was not well-studied in the Arkansas flora and only P. aurea was known from the state in the naturalized condition. Field work in 2025 by the authors in central and western Arkansas has increased the known distribution of P. aurea and documented the first occurrences of three additional species of Phyllostachys: P. aureosulcata, P. bambusoides, and P. nigra outside of cultivation. Whereas P. bambusoides and P. nigra are infrequent (known from 2 and 1 county, respectively), P. aureosulcata has a more wide-spread distribution in Arkansas, where it is documented from several counties. Phyllostachys aureosulcata and P. aurea are similar morphologically and easily confused without close examination, which may explain why P. aureosulcata remained undetected in the state’s flora until now. Keys to identification of Arkansas Phyllostachys species and morphologically similar taxa, diagnostic and habitat photographs, current state distributions, and notes on their ecology and invasiveness are provided.
