If you have recently travelled along SH1 between Wellington and Paekakariki you may have noticed that some of the roadside cuttings and banks are tinged with pink. The culprit is the daisy pink ragwort (Senecio glastifolius). Pink ragwort is native to a small area of coastline in South Africa and was first recorded

Although the frond is small and lacking the diagnostic reproductive characters, I think it is the introduced holly fern (Cyrtomium falcatum). It looks like the shining spleenwort (Asplenium oblongifolium), but the
