Gentianopsis virgata

Gentianopsis virgata (commonly called "lesser fringed gentian", "narrow-leaved fringed gentian", or "smaller fringed gentian") is a biennial herbaceous species, native to eastern USA and eastern Canada. 

Taxonomy
Broadly transcribed, Gentianopsis crinita (Froel.)  Ma is an eastern North American species complex, containing a group of closely related taxa, including G. virgata.  Further species were described in the past, but a lack of difference in nrDNA and morphology does not support their recognition.  Three subspecies are currently recognized:

Gentianopsis virgata (Raf.)  Holub subsp.  virgata
Gentianopsis virgata subsp.  victorinii (Fernald) Lammers
Gentianopsis virgata subsp.  macounii (Holm) J.S. Pringle
