The epithet hortensia is a noun in apposition (www.ipni.org/index.html). Hortensia is a synonym of Hydrangea, of which some species have dense corymbs of blue flowers like those of Myosotidium. The epithet is not to be altered to hortensium as by Heenan & Schönberger (2009) and de Lange et al. (2010, 2013).Garnock-Jones, P.J. 2014: Evidence-based review of the taxonomic status of New Zealand’s endemic seed plant genera. New Zealand Journal of Botany 52(2): 163–212.
