TL;DR: Thirteen additional characters taken from stem, leaf, involucre, corolla and achenes together with geographical data were used to show that the two major groups and only one subgroup exhibit taxonomic properties.
Abstract: Summary Thirteen numerical attributes taken from phyllaries, calycule, peduncle and florets were recorded for a sample of 65 specimens representing the New Zealand Erechtites arguta (syn. Senecio glomeratus)—Erechtites scaberula (syn. Senecio hispidulus) complex. The comparative data were subjected to computer analyses using Squared Euclidean Distance (D2 ) and Gower's Index as similarity statistics in conjunction with Nearest. Median and Furthest neighbour and Centroid (C) sorting strategies during the commissioning of ASSORT, a package of interrelated Algol procedures. The resulting agglomerative polythetic classifications conform to a basic structure exemplified by the D2 -C result. Two major groups consisting of four and five subgroups respectively were detected from the computed hierarchy. Thirteen additional characters taken from stem, leaf, involucre, corolla and achenes together with geographical data were used to show that the two major groups and only one subgroup exhibit taxonomic properties.
