Dendrogram Based on Morphological Characters Described in the FTEA. Using gross morphological characters of the ten Plectranthus species previously described in Table 1, the following character state matrix (Table 5) was created and subjected to hierarchical cluster analysis.
The dendrogram shows taxonomic relationships among the Plectranthus species based on gross morphological characters as described in FTEA .
Such relationships of Plectranthus species described in the FTEA were very similar to what has been observed from the phylogenetic trees created from the MatK and Rbcl gene sequences in the current study.
