Abstract

To clarify the taxonomic status of Arundinella setosa var. tengchongensis and its relationships with A. setosa var. setosa and other related species, molecular phylogenetic analyses based on nuclear ITS and two plastid DNA (matK and trnL-F) sequences, and morphological comparisons using one-way ANOVA were carried out. Our results reveal that A. setosa var. tengchongensis is recovered within a different clade and separated from the type variety. Morphologically, A. setosa var. tengchongensis can be easily distinguished from A. setosa var. setosa and other varieties by its smaller spikelets, shorter awns, and bearded nodes. Thus, A. setosa var. tengchongensis is here elevated to the species rank and newly combined as A. tengchongensis.
