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.
