The range of Malacothamnus hallii is adjacent to M. arcuatus s.s with morphological intermediates where their ranges meet. Phylogenetic analyses place both taxa in the same clade with some analyses indicating some divergence. While future research may show that M. arcuatus and M. hallii should be treated as two species, the 2023 treatment treats M. hallii as M. arcuatus var. elmeri, the elmeri part having taxonomic priority over hallii when treated as a variety. Placing both taxa in the same species allows intermediates to be classified to the species rank.
The suggested common name in the 2023 treatment for M. arcuatus at the species rank (s.l.) is bewildering bushmallow, which alludes to the taxonomic problems from the 2012 Jepson treatment where the author identified specimens of M. arcuatus s.s. as an amazingly large number of other species, presumably as M. arcuatus confounded her analyses. The common names of each variety adds their geographic placement relative to each other. M. arcuatus var. arcuatus is western bewildering bushmallow. M. arcuatus var. elmeri is eastern bewildering bushmallow.

Los desacuerdos no deseados ocurren cuando un padre (B) es
disminuido al mover un hijo (E) a otra parte del árbol taxonómico,
resultando en que los IDs existentes del padre sean interpretados
como desacuerdos con los IDs existentes del hijo movido.
Identification
ID 2 del taxón E será un desacuerdo no deseado con la ID 1 del taxón B después del cambio de taxon
Si disminuir a un padre resulta en más de 10 desacuerdos no deseados, debes dividir al padre después de cambiar al hijo para reemplazar las identificaciones existentes de
el padre (B) con identificaciones que no están en desacuerdo.
