FIGURE 4 in Integration of nuclear and mitochondrial gene sequences and morphology reveals unexpected diversity in the forest cobra (Naja melanoleuca) species complex in Central and West Africa (Serpentes: Elapidae)
FIGURE 4. Ordination of individual specimens and OTU centroids of four of the mitochondrially defined candidate species of the N. melanoleuca complex along the first two canonical variates. CS5-peroescobari was omitted due to the small available sample size. Canonical variates 1 and 2 account for 57.9 and 22.8% of total variance, respectively. Enlarged symbols indicate OTU centroids.

Top left: specimen from Kakamega, western Kenya, illustrating the typically deep black and white specimens with strong facial markings from the periphery of Lake Victoria. Bottom left: specimen from Chuka, Mount Kenya, Kenya, illustrating an extreme of the brown forebody and reduced facial pigmentation typical of the species in much of its range. Photos W. Wüster, courtesy Royjan Taylor / Bio-Ken snake farm live collection, Watamu, Kenya.

FIGURE 3 in Sansevieria (Asparagaceae, Nolinoideae) is a herbaceous clade within Dracaena: inference from non-coding plastid and nuclear DNA sequence data
FIGURE 3. Bayesian maximum clade reliability trees based on combined nuclear At103 and chloroplast rps16, trnL-F datasets for Dracaena, Sansevieria, and selected outgroups. The values above the branch represent the maximum parsimony bootstrap percentage (BS), and the ones below are the Bayesian posterior probability (PP). Bold branches indicate strong support, interpreted as ≥ 70 BS and ≥ 95 PP. Long branches were shortened by half their length (indicated by \\).
