APPENDIX 2 in An integrative taxonomic revision of Aneuraceae H.Klinggr. (Marchantiophyta) from Guadeloupe and Martinique, French West Indies

APPENDIX 2. — ASAP partitions: the fifth best ASAP scores were retained. We retained the first and the third (2 and 4.5) because the partition with the second best score (3) merges three morphological very distinct species (R. palmata (Hedw.) Carruth., R. gasparii Reeb & Gradst. and R. crenulata Schiffn.). In the left column, the final hypothesis proposed by this study are reported, and colored bars indicate the retained species, even if the two scores we retained merged them (e.g. R. fucoidea (Sw.) C.Massal. and R. hymenophytoides (Spruce) Meenks).
