This segregate of viorna is known mostly from rocky base-rich soils in and around the Interior Low Plateaus, especially on limestone points above cliffs in the Bluegrass, Knobs and locally in the Mississippian Plteaus (D, F, W). The type of flaccida was collected by S. Price from a cave entrance in WARR (NY, MO), and B later reported it from several counties in Ky.. Compared to typical viorna, flaccida has relatively hairy lower leaf surfaces and outer sepal surfaces. Other characters have been indicated by D. Estes, Z. Irick (pers. comm.) and W, but deserve further testing;.There may be transitions to the more strictly Appalachian variant of non-calcareous regions named here viorna sensu stricto and variety status may be more appropriate; see notes under viorna. The names Viorna flaccida or V. gattingeri Small may both be included with the plants mapped here, and revision is ongoing (D. Estes, pers. comm.). C. cf. flaccida and viorna are largely replaced by versicolor and glaucophylla further south and west. However, both flaccida and viorna appear to be part of variable complexes, with posible hybrids and additional local variants; see provisional keys in W. Some of the more disjunct western and southern colls. mapped here resemble other variants found in southern foothills from S.C. to Ala. (including Viorna beadlei Small) and Ala. to e. Tex. (including V. subreticulata Harbison). Such plants include colls. from TRIG and Montgomery Co., Tenn. (ASPC) with relatively broad, thinly hairy, more or less subreticulate leaflets. They may appear transitional from flaccida to pitcheri or even C. reticulata (Walt.) Small; see notes under pitcheri.
