FIGURES 7–11 in Reinstatement of Phrix (Delesseriaceae, Rhodophyta) based on DNA sequence analyses and morpho-anatomical evidence

FIGURES 7–11. Phrix spatulata (E.Y. Dawson) comb. nov. 7. Apex of blade with numerous fusiform spermatangial sori in series between lateral veins of the wings. Scale bar = 200 μm. 8. Permanent mount slide showing folded blade margin and sori (one indicated by arrow) with branching of spermatangial mother cells and spermatangia (one indicated by small arrow). Scale bar = 50 μm. 9. Excised mature blade 18 mm long with 6 secondary blades. Scale bar = 2 mm. 10–11. Permanent mount slide showing apical (10) and middle (11) parts of blade. Note undivided pericentral cells (arrows show one in each Fig) as well as incipient spermatangial sori (one indicated by asterisk in Fig. 11). Scale bars = 50 μm.
