ILLUSTRATIONS. — Engel & Glenny 2008: 423, fig. 94 and 426, fig. 95; Zhou et al. 2012: 12, fig. 2; Meagher 2019: 315, fig. 2.

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.
