The species is characterized by its elongate side leaves tapering much to the trilobate apex. Its underleaf sinuate without hyaline cells and with auriculate base. Bakalin & Nguyen (2016) enumerates it from Vietnam, erroneously referring to Pócs (1971), where it is not mentioned and till now unknown from the country. Bazzania asymmetrica is a rare species with scattered distribution in New Guinea, Borneo and southern China and is new to Thailand ( Lai et al. 2008).
