Pennantia baylisiana - technically has no common name - some people like to call it 'Three Kings Kaikomako' which to me is a terrible construct because it has little resemblance to Pennantia corymbosa (kaikomako). As far as I am concerned it has no common name. As Astrid points out the species is well described and illustrated on the NZPCN website. Failing that try reading the account in: de Lange, P.J.; Heenan, P.B.; Norton, D.A.; Rolfe, J.R.; Sawyer, J.W.D. 2010: Threatened Plants of New Zealand. Christchurch, Canterbury University Press. 471pp. - available from CUP.
