Figure 6.
(A) Scatter plots of five morphological characters: width:length ratio for the terminal (term_dim) and lateral (lat_dim) leaflets; ratio of terminal:lateral petiolule length (pet_dim); number of hairs in a 9 mm2 area on the abaxial surface of the terminal leaflet (hairs); and first principal component of the elliptic Fourier analysis of the lateral leaflet (lat_PC1). (B) Phylogenetic relationships among the three groups, with an example of the typical terminal and lateral leaflet shape and hairiness. Lineage names according to Parker (1996) are given in parentheses.
