Figures 11–30: NeoharaldiophyllUm Udoense (M.S. Kim et J.C. Kang) J.C. Kang et M.S. Kim comb. nov. Vegetative structures. (11–12) Holdfast and stipe from rope (11) and rhodolith (12). (13) Cross-section of stipe. (14) Basal portion of blade with the evanescent fanwise radiating thickened nerves. (15–19) Cross-sections of blade through base (15), nerves (16), lower (17), middle (18) and upper (19) portions of blade. (20–23) Cortical cells and chloroplasts from the near meristematic (20), upper (21), middle (22) and lower (23) parts of blade. (24) Diagram of apical organization of young blade with the order of cell-rows (numbers) and cells produced by intercalary divisions (i), thick-walled cells (black arrows) budded off from cortical cells, and linked by secondary pit connections to adjacent cells, and traces of oblique divisions (red arrowheads). (25–26) Tips of young thalli growing by means of transverse (25) and oblique (26) divisions of an apical cell. (27–28) Tips of mature blades with transversely (27) and obliquely (28) dividing apical cell. (29–30) Marginal crenulations.
