Sequences were compared specifying gaps as missing data with the pairwise deletion option: (A) combined ITS region distance matrix; (B) average distance matrix within and between groups of Spanish and non-Spanish Haplophyllum species.

Numbers and letters along the top and left margins of each matrix correspond to samples. 1, H. blanchei; 2, H. linifolium; 3, H. coronatum; 4, H. rosmarinifolium; 5, H. suaveolens; 6, H. bastetanum; S, Spanish Haplophyllum species; R, non-Spanish Haplophyllum species.
