FIGURE 4 in First occurrence of Gracilaria chilensis, and distribution of Gracilariopsis lemaneiformis (Gracilariaceae, Gracilariales) in Peru on the basis of rbcL sequence analysis
FIGURE 4. Phylogenetic tree based on rbcL sequences inferred from a maximum-likelihood analysis as implemented by RAxML. Taxa highlighted in red were newly sequenced for this study. GenBank numbers are listed after each taxon. Bootstrap proportions (>50%) for ML (1000 replicates, Left) and Bayesian Posterior Probability (Right) are shown at the nodes. Full support denoted as *.

FIGURE 11. Neighbor-joining phylogram for the UPA region showing the grouping of the specimens sequenced in this study (in bold) and available from Genbank. Taxa names are followed by herbarium voucher or field ID numbers (new sequences) or access numbers (sequences from Genbank). Bootstrap support values> 50 are indicated.
