Fig. 1. Maximum likelihood tree for rbcL sequences of Osmundea and Laurencia species, rooted with Halopithys incurvus, Lophocladia trichoclados and Chondria dasyphylla. Branch lengths are proportional to the amount of sequence change, and bootstrap values (1000 replicates) for MP (top), NJ (middle) and ML (bottom) are indicated at the nodes.
Fig. 2. Parsimony tree for rbcL sequences of Osmundea and Laurencia species (the roots pruned) showing character states for the presence (blue) or absence (red) of secondary pit connections (upper tree) and the shape (urn-shaped, blue; cup-shaped, red; trichoblast-type, black) of the spermatangial receptacles (lower tree).
