editorial
Flora II (clearly aware of Koyama’s publications) uses the combinations in Baumeaand cites Koyama’s combinations in Machaerinaas synonyms. Brummitt, R.K. (1992), Vascular Plant Families and Genera: 58; Goetghebeur, P. in Kubitzki, K. (Ed) (1998), The Families and Genera of Vascular Plants 4: 180-181, and Mabberley, D.J. (2008), Mabberley's Plant-Book Edn. 3.: 509; Flora of China etc. all have Marchaerinaas preferred name and Baumeaas a synonym. NZ was the last country left still using Baumea,. All other countries have switched back over to Machaerina(Australia, Africa, etc.). Unpublished DNA data also supports putting Baumea and Machaerina together.
