The taxonomy of the Sino-Himalayan alpine bamboos is controversial due to their complex evolutionary history and further complicated by scarcity inflorescence. Here, we supplement description inflorescence Fargesiaangustissima T.P. Yi Yushaniapauciramificans Yi, which shed light on Fargesia Franchet, Borinda Stapleton Yushania Keng. F.angustissima has compressed unilateral stretching out from reduced spathe, showing a transitional state between species with condensed embraced spathe-like bracts open without bracts. Considering that extensive gene flow existed several clades found in recent studies, broadly-defined s. l. should be adopted. Meanwhile, Y.pauciramificans typical characteristics Yushania, such as axilla tuberculate glands, rachilla internodes ciliate cylindrical florets, supporting delimitation Yushania.
