Glossary (beta!)

Subgenus: Senega. Section: Verticillatae.

Origin/Endemic status: Native

Taxonomy Comments: Through most of its range S. ambigua has wings 1.3-1.7 mm long; plants from se. VA south to SC and from the Ozarks have wings 2.0-2.6 mm long. These plants have been named as a variety of Polygala verticillata, var. dolichoptera Fernald. They may warrant taxonomic recognition, but need additional study, including resolution of our Coastal Plain plants and those of the Ozarks.
