FIGURES 1–6 in Reinstatement of Phrix (Delesseriaceae, Rhodophyta) based on DNA sequence analyses and morpho-anatomical evidence

FIGURES 1–6. Phrix spatulata (E.Y. Dawson) comb. nov. 1. Living branches ramifying through dead blade. Scale bar = 50 μm. 2. Live filament extends through axial filament of dead blade and into culture medium. Scale bar = 150 μm. 3. This filamentous basal system attached to glass was derived from a single excised filament. The levorotary growth pattern expands outward. At the center of the basal disc numerous coalescent parallel filaments occur at the bases of developing blades. Scale bar = 1 mm. 4. Formation, coalescence and elongation of horizontal filaments. Shoot on right with central axial filament enclosed by parallel adherent branches bearing oblique uniseriate laterals projecting toward middle shoot also enclosed by parallel filaments. Middle shoot has 3 uniseriate laterals growing toward and attaching to uniseriate shoot on left. Scale bar = 100 μm. 5. Basal system of radiating filaments developing into thick structure of adherent parallel filaments projecting up and around lower blade. Scale bar = 70 μm. 6. Two young blades arising from thickened bases like that in Fig. 5 entangled with live filaments. Scale bar = 200 μm.
