GENUS INDEX
GENUS CODE: GENTI GENUS SCIENTIFIC:Gentiana GENUS AUTHORITY: L. GENUS COMMON: Gentian GENUS SUMMARY: A genus of about 350-400 species, herbs, primarily temperate and arctic. Even following the removal of Gentianopsis and Gentianella (to separate genera and a different subtribe), Gentiana is a large and apparently heterogeneous group, perhaps not monophyletic. No satisfactory comprehensive treatment is available, however. All of the species treated here as Gentiana are in the distinctive group often treated as section, subgenus, or genus Pneumonanthe. GENUS IDENTIFICATION: Identification Notes: In some species it may be somewhat difficult to interpret the corolla lobes and the corolla appendages. The filaments are alternate to the corolla lobes, and are therefore attached to the lower portion of the corolla appendages.

Plant Sale Text: Pine-barren gentian is endemic to the pine barrens of New Jersey and Delaware and the coastal plain of the Carolinas. Once thought to be of limited occurrence, increased use of prescribed fire in longleaf pine ecosystem management has revealed this species local abundance. Pine-barren gentian’s bright blue flower petals open outward to expose the sexual organs of the flower unlike the bottle-type gentians. Except for its relatively large flower, one might not notice the pine-barren gentian in passing.

PHENOLOGY:
HABITAT: Longleaf pine savannas, pine flatwoods, sandhills, pine barrens, in a variety of sites varying from moist to very xeric, in se. VA, NC, and SC nearly always associated with Pinus palustris and/or Aristida stricta.
COMMENTS: Late Sep-mid Jan (rarely at other times of the year, such as spring, in response to fire). This species is a bimodal endemic, occurring in s. NJ and adjacent DE (at least formerly), and from se. VA south through e. NC to nc. SC. The related G. pennelliana Fernald (sometimes reduced to a subspecies of G. autumnalis) is endemic to the FL Panhandle; other siblings, G. bicuspidata (G. Don) Briquet, G. hooperi Pringle, and G. longicollis G.L. Nesom, occur in Mexico. G. autumnalis is often overlooked, since it is very inconspicuous except when in flower, it usually flowers at a season when few botanists are about, and sterile plants greatly outnumber fertile ones. Vegetatively it is extremely distinctive once learned; the leaves are glossy, dark-green, opposite,oblanceolate to oblinear, and twisted and curved in a manner reminiscent of an airplane propellor.
