Multiple research questions are being pursued towards better understanding of the genus Stellaria (starworts) and close relatives.

Systematics & Taxonomy:

Phylogenetic synthesis of the genus Stellaria:

Taxonomic notes on the genus Stellaria:

“Taxonomic Observations within Stellaria (Caryophyllaceae): Insights from Ecology, Geography, Morphology, and Phylogeny Suggest Widespread Parallelism in Starworts and Erode Previous Infrageneric Classifications”

Taxonomy of taxa lumped intoStellaria alsine and a new Tertiary disjunction:

Biogeography:

A biogeographic synthesis of the genus Stellaria, with ancestral area reconstruction, aspects of niche/ecological evolution, one of the great long distance dispersal events in angiosperms, and interesting new insights into Tertiary disjunctions:

Recognition of this species was published in Taxon:

“RAD Sequencing Rejects a Long-Distance Disjunction in Stellaria L. (Caryophyllaceae) and Yields Support for a New Southern Rocky Mountains Endemic”

Floral Evolution:
