根据在云南采集到的标本,对竹亚科牡竹属马来甜龙竹的花序特征做了较为详细的中文以及拉丁文补充描述,对马来甜龙竹和小叶龙竹的果实特征进行了描述。

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