﻿AbstractSasaoblongulawas described in 1987 based on a cultivated plant at the bamboo garden of Sun Yat-sen University. This species has two or three branches at the upper nodes, which differ from the rest ofSasaspecies that have a single branch per node. During the field trip to Baishi Town, Yunfu City, Guangdong Province in July 2021, one bamboo species with oblong foliage leaves was collected and matches the isotype. Then, our question was to test the identity ofS.oblongulaconcerning otherSasaspecies based on morphology and molecular data. To do that, we sequenced the whole chloroplast genome ofS.oblongulaand did a phylogenetic analysis. Our morphological results indicate that the new collection isS.oblongula. The phylogenetic tree showed thatS.oblongulais close toPseudosasa, instead ofSasaspecies. Therefore, we transferred it to the genusPseudosasa, and a revised description ofP.oblongulais provided here.
