Fig. 3 in The Crinum flaccidum (Amaryllidaceae) species complex in Australia

Fig. 3. Three-dimensional NMDS of Crinum flac-cidum and C. luteolum with biplot analysis of the morphological data using Gower similarity. The vectors are the biplot analysis of the 16 variable morphological characters (Table S3), where direc-tion and length are the extent to which the char-acters are affecting the species complex in the dendrogram (Fig. 2). Group 1 (light blue) consists of all New South Wales Crinum flaccidum samples; Group 2 (dark blue) comprises all South Australian C. flaccdium; and Group 3 was formed using all C. luteolum. The ordination plot has a STRESS score of 11.84%. The polygons represent the area covered by each group. Sample and character codes can be found in Tables S1 and S3 respectively.
