Notes on the marine algae of the Bermudas. 15. Dichotomaria huismanii (Galaxauraceae, Rhodophyta), a new species in the D. marginata complex from the western Atlantic
(Ellis & Solander) Ellis & Solander, 1786
Figures 3–6: Dichotomaria marginata. (3) Lectotype of Corallina marginata (=Dichotomaria marginata): Ellis and Solander illustration (1786, pl. 22 figure 6). (4) Sample from St. Croix (STX032), scale bar=2 cm. (5) Section through outer cortex showing subcortical cell bearing a pair of assimilatory outer cortical cells, scale bar=25 µm. (6) Surface view of outer cortical assimilatory cells (STX054), scale bar=25 µm.
Figure 1: Species groups in the Galaxauraceae determined with UPGMA clustering of the COI-5P genetic barcode, with Scinaia and Liagora as outgroups. Sequences generated for this study are in bold text.
Figure 2: Phylogeny of the Galaxauraceae based on maximum-likelihood analyses of rbcL sequences. Branch values are bootstrap supports for ML (1000 replicates) followed by Bayesian posterior probabilities expressed as a percentage of support out of 1. An asterisk (*) indicates 100% support for both robustness metrics while a dash (-) indicates support values <60%. Sequences generated for this study are in bold text.
