general taxon notes:
Pelekium consists of three species, with their main distribution in tropical Asia. B.-Y. Yang and W.-C. Lee (1964) and Watanabe (1972) reported both Pelekium bifarium (Bosch & Sande Lac.) Fleisch. and P. velatum Mitt. from Taiwan. L. Zhang (1990) recently reported the former species from southern Yunnan. In the present study, two species are treated for China.
