Abstract
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.

Methods
Morphometric measurements were made from 95 herbarium specimens using a ruler and digital calipers. The herbarium specimens were sourced from three herbaria: MO, NY, and QCA. Measurements include 23 continuous quantitative variables and two qualitative variables, which are described in more detail in the README file. The measurements are unprocessed.
