Psorodendron spinosum (A.Gray) Rydb. View in CoL = Dalea spinosa A.Gray = Asagraea spinosa (A.Gray) Baillon = Parosella spinosa (A.Gray) A. Hell. = Psorothamnus spinosus (A.Gray) Barneby.
4. Dalea is paraphyletic with respect to Marina , as D. filiciformis results sister to Marina . This result was obtained in all the partitioned and the combined analyses, including that based on the ITS- trnK/matK dataset with a significantly increased sampling within the species-rich Dalea . The bootstrap values that support this particular result ranged from 95 % in the ITS-based analysis (Suppl. Fig. 1 View Figure 1 ) to 100 % in the combined ITS + matK/trnK analysis ( Fig. 2 View Figure 2 ). Barneby (1977: 149) already stated that D. filiciformis “has no really close relative in Dalea and its affinities are difficult to estimate,” and pointed out its pod morphology resembles that found in Marina species. Thus, the following formal transfer is required:
