FIGURE 7 in Multilocus phylogeny reveals Gibsmithia hawaiiensis (Dumontiaceae, Rhodophyta) to be a species complex from the Indo-Pacific, with the proposal of G. eilatensis sp. nov.

FIGURE 7. Gibsmithia eilatensis sp. nov. Early post-fertilization stages. A) Vegetative lateral branch (arrowhead) on basal cell of carpogonial filament, and curved hypogynous cell (arrow). Slide DG210-4. Scale bar 50 μm. B) Presumed early fertilization stage showing lateral extension of carpogonium and hypogynous cell (arrowhead). Slide DG210-1. Scale bar 50 μm. C) Auxiliary cell branch. Slide DG234-4. Scale bar 50 μm. D) Unsegmented incoming connecting filament (ic) partly and laterally fused to auxiliary cell, and unseptated outgoing connecting filament (oc). Slide DG234-2. Scale bar 100 μm. E) Incoming connecting filament (ic) segment partly fused with auxiliary cell, and outgoing connecting filament (oc) segment (arrow) partly fused with nearby auxiliary cell. Slide DG234- 3. Scale bar 50 μm. F) Gonimoblast initial (arrow) developed from the short segment partly fused to auxiliary cell, between incoming connecting filament (ic) and outgoing connecting filament (oc). Slide DG234-3. Scale bar 50 μm. G–H) Multiple gonimoblast initials cut off bilaterally from connecting filament segment (arrow) fused to auxiliary cell. G) Slide DG234-3. Scale bar 50 μm. H) Slide DG234-5. Scale bar 50 μm. I) Young clusters of spermatangia (arrow) formed terminally and laterally in assimilatory filaments. Slide DG220-1. Scale bar 50 μm.
