In this paper, supplementary descriptions in Latin and Chinese are provided for inflorescence and fruit characters of Dendrocalamus asper and fruit characters of D.barbatus. The new specimens indicate that flowering branches of D.asper are leafless, 0.5-3m long, and each node bears 3-6 pseudospikelets or 10-25 (-30) pseudospikelets clustered in a spiky globose mass, with 1.5-2cm in diameter; pseudospikelet comprises 4 or 5 florets, and apical one is fertile; fruits are nut-like caryopsis, nearly globose, with 2-4mm in diameter; and apex of caryopsis remains persistent style base which is 1-2mm long and covered with cilia. The fruits of D. barbatus are also nut-like caryopsis, cylindrical, 6-10mm long, 1.2-2mm in diameter;and apex of caryopsis remains persistent style base which is 2-3mm long and covered with cilia.
