Hybanthus

Hybanthus concolor

Of the four species of Hybanthus (greenviolets) that are native to North America, only Hybanthus concolor (the eastern greenviolet) has been discovered outside of cultivation in New York.

Viola

The Viola genus has about 50 species found outside of cultivation in New York. The majority of the species are native to the region, though a few are escaped garden exotics. The subgeneric organization used here is is largely based on Ballard (1999).^[1]

Violets are often divided into two groups based on the presence of a stem that is shared between the flowers and leaves. "Stemmed" or "caulescent" means that the flowers and leaves share an above-ground stem, whereas "stemless" or "acaulescent" violets have separate petioles (attached to the leaves) and peduncles (attached to the flowers) that arise from an underground rootstock.

Viola sect. Melanium

Viola bicolor

The Viola section Melanium contains plants commonly known as pansies. The only North American native pansy is Viola bicolor, which is also the only annual Viola species with cleistogamous (small inconspicuous closed self-pollinating) flowers. It is listed as endangered in New York State.

Viola sect. Viola subsect. Boreali-Americanae

Viola affinis Leconte (LeConte's violet) from Homer D. House, Wild Flowers of New York, 1918.

The taxa of Viola subsection Boreali-Americanae W.Becker are native exclusively to North America (including northern Mexico). They are commonly referred to as the "stemless (or acaulescent) blue violets", as the leaf petioles and flower peduncles arise directly from the rhizome instead of from a shared above-ground stem. Their classification has long been in flux, partially due to apparent introgressive hybridization within the subsection.^[1]
