Co-Innovation Center for Sustainable Forestry in Southern China, Nanjing Forestry University, Nanjing 210037, ChinaThe flowering habit of Pleioblastus yixingensis was observed at first, and the inflorescence morphological structure was described. Genus Pleioblastus has 3 stamens according to the Flora Reipublicae Popularis Sinicae, but the number of stamens with 3, 4, 5 or 6 were observed during field investigation, of which 3 was the majority. These enriched the data of Pleioblastus. The boron was not necessary element during pollen germination. The pollen was stained aborted with germination rate only 5.11%, which was an important reason of low setting of P. yixingensis. Pleioblastus yixingensis in Henan, Jiangsu, Zhejiang, Anhui was synchronized flowering in 2017 with fruiting rate less than 10%.
