Morphometrics in the recurved corolla clade of Burmeistera (Campanulaceae)

In this study, we used morphometric data to test species boundaries in the
genus Burmeistera (Campanulaceae). Morphometrics measurements were made on
herbarium specimens from a monophyletic clade of three species with
recurved corolla lobes: B. crispiloba, B. sodiroana, B.
succulenta. We used using both hierarchical and normal mixture model-based
clustering methods to test the current species hypotheses. Our results
support the recognition of the three known species plus a new species
described in the paper.
