The Phylogenetic Relationships Of Lembocarpus And Goyazia (Gesneriaceae) Based On NdhF Sequences, James F. Smith

Biology Faculty Publications and Presentations

The phylogenetic relationships of Goyazia and Lembocarpus are investigated based on cladistic analysis of ndhF sequences. Both genera are currently classified in the tribe Gloxinieae, but both are poorly known. Based on its floral morphology, the classification of Goyazia in Gloxinieae is not controversial. Lembocarpus may be placed in Gloxinieae, Episcieae, or Sinningieae. The acaulescent, tuberous nature of Lembocarpus limits the number of characters available for a morphological analysis and has made its classification and phylogenetic relationships difficult to resolve. Phylogenetic analyses of ndhF sequences place both genera in Gloxinieae. Although the affinities within the tribe are ambiguous …
