Molecular Phylogeny and Taxonomic Revision of the Genus Diastatea (Campanulaceae: Lobelioideae)

This dataset contains the digitized treatments in Plazi based on the original journal article Johnson, Elizabeth P., Ayers, Tina J. (2022): Molecular Phylogeny and Taxonomic Revision of the Genus Diastatea (Campanulaceae: Lobelioideae). Systematic Botany (Basel, Switzerland) 47 (1): 61-84, DOI: 10.1600/036364422X16442668423392, URL: doi.org/10.1600/036364422x16442668423392 Abstract — Diastatea (Campanulaceae-Lobelioideae) is a genus of small, herbaceous annuals found mostly in Mexico.

Differences in the number of recognized species in the historical treatments, and the lack of a phylogeny, suggested that a revision of the genus was necessary. Species boundaries and species level relationships were tested based on a sampling of nearly 50 individuals. Sequences of the chloroplast spacer regions, atpB-rbcL and ndhF-rpl32, as well as the ITS, were generated and then analyzed using maximum likelihood and Bayesian inference methods.
