NOTES

It occurs in south China and Thailand and widespread from Australia through Melanesia to the Society Islands (Miller et al. 1983; Zhou et al. 2012). New to Vietnam. It is a very variable taxon with underleaves connate on both sides with the side leaves. Bazzania adnexa closely related to and vicariant of the African Bazzania decrescens (Lehm. & Lindenb.) Trevis. Their relationship should be clarified by molecular methods.
