While attempting to clarify the circumscription of <jats:italic>Arthrostylidium</jats:italic>, we discovered three West Indian species (<jats:italic>A. angustifolium, A. farctum, A. pinifolium</jats:italic>) that possess putative Guaduinae features. We test the hypothesis that these three species should be classified within subtribe Guaduinae and revise their taxonomy. Phylogenetic inference based on sequences of four plastid markers (<jats:italic>ndhF, trnC\u2010rpoB, trnD\u2010trnT, rps16\u2010trnQ</jats:italic>) recovered <jats:italic>Arthrostylidium</jats:italic> as polyphyletic, with <jats:italic>A. angustifolium, A. farctum</jats:italic>, and <jats:italic>A. pinifolium</jats:italic> forming a well\u2010supported clade sister to the Guaduinae. Parametric bootstrap tests uphold this topology as significant. Detailed morphological and anatomical analyses revealed <jats:italic>A. angustifolium, A. farctum</jats:italic>, and <jats:italic>A. pinifolium</jats:italic> lack characteristics diagnostic for Arthrostylidiinae but conform to Guaduinae.
