Muehlbergella is a monotypic genus of flowering plants in the family Campanulaceae. It contains a single species, Muehlbergella oweriniana. It is critically endangered
The species is endemic to an area of ~40 km2 in Dagestan, North Caucasus, where it grows between cracks and calcareous rocky ground.[1]
The genus and species were both described by Heinrich Feer and published in Botanische Jahrbücher für Systematik, Pflanzengeschichte und Pflanzengeographie Vol.12 (Issue 5) on pages 615–616 in 1890.[2]
The genus name of Muehlbergella is in honour of Friedrich Mühlberg (1840–1915), a Swiss geologist.[3] The Latin specific epithet of oweriniana refers to the original collector, Alexander Pavlovic Owerin, a Russian military topographer, florist, and botanical collector. Owerin had collected plants from the mountains of Dagestan (1860–61) and other places in the Caucasus.[4]
