Heads up: Some or all of the identifications affected by
this split may have been replaced with identifications of Holochloa. This
happens when we can't automatically assign an identification to one of the
output taxa.

Folk, R. A., & Freudenstein, J. V. (2015). “Sky islands” in the eastern U.S.A.? — Strong phylogenetic structure in the Heuchera parviflora group (Saxifragaceae). Taxon, 64(2), 254–271. doi:10.12705/642.3
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)
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?)
Unintended disagreements occur when a parent (B) is
thinned by swapping a child (E) to another part of the
taxonomic tree, resulting in existing IDs of the parent being interpreted
as disagreements with existing IDs of the swapped child.
Identification
ID 2 of taxon E will be an unintended disagreement with ID 1 of taxon B after the taxon swap
If thinning a parent results in more than 10 unintended disagreements, you
should split the parent after swapping the child to replace existing IDs
of the parent (B) with IDs that don't disagree.
Why should this change be applied to species in the western United States and Europe?
