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:

Phylogenetic Relationships Within and Delimitation of the Cosmopolitan Flowering Plant Genus Stellaria L. (Caryophyllaceae): Core Stars and Fallen Stars

Taxonomic notes on the genus Stellaria:

Recognition of this species was published last year 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:

Work detailing some pollination biology and floral evolution in Stellaria is in revision at present. Here is the habitat of an experimental starwort system in Colorado:
