We present the first multi-locus chloroplast phylogeny of Arthrostylidiinae, a subtribe of neotropical 26 woody bamboos. The morphological diversity of Arthrostylidiinae makes its taxonomy difficult and prior molecular analyses of bamboos have lacked breadth of sampling within the subtribe, leaving internal 28 relationships uncertain. We sampled 51 taxa, chosen to span the range of taxonomic diversity and mor phology, and analyzed a combined chloroplast DNA dataset with six chloroplast regions: ndhF, trnD-trnT, 30 trnC-rpoB, rps16-trnQ, trnT-trnL, and rpl16. A consensus of maximum parsimony and Bayesian inference  analyses reveals monophyly of the Arthrostylidiinae and four moderately supported lineages within it. 32 Six previously recognized genera were monophyletic, three polyphyletic, and two monotypic; Rhipidocladum sect. Didymogonyx is here raised to generic status. When mapped onto our topology, many of the 34 morphological characters show homoplasy.
