Species Distribution Leaves Flowers Habitat
Heuchera puberula Ozark Plateau (Missouri and Arkansas) Leathery, with short-hairy petioles (less than 0.5 mm) Bracts mostly entire Calciphile (dolomite/limestone), more exposed areas, riparian
Heuchera missouriensis Interior Plateau and southern Cumberland (southern Illinois, southern Indiana, extreme eastern Missouri, western Kentucky, parts of Tennessee, northern Alabama) Membranous, thin, petioles long-hairy (usually >0.6 mm) Bracts mostly trifid, styles exserted <1.25 mm, inflorescence notably condensed, with lower pedicels mostly <5 mm, flower orientation subhorizontal Rockhouses, only occasionally riparian
Heuchera parviflora var. parviflora Northern Cumberland, disjunct in the southern Appalachian Escarpment (southern Ohio, eastern Kentucky, parts of Tennessee, western North Carolina, parts of western South Carolina and northern Georgia?) Membranous, thin, petioles long-hairy (usually >0.6 mm) Styles exserted <1.75 mm, inflorescence open, lower pedicals mostly >5 mm, flowers pendant Exclusive to sandstone
Heuchera parviflora var. saurensis Endemic to North Carolina in Piedmont, mostly in Sauratown Mts, also foothills of Appalachians Mature leaves strongly sticky-viscid, membranous, thin, petioles long-hairy (usually >0.6 mm) Styles exserted <1.75 mm, inflorescence open, lower pedicals mostly >5 mm, flowers pendant Exclusive to quartzite

Any Heuchera parviflora misidentified in areas outside its range would be kicked up to section. Is that what you're referring to?
