Taxonomic Comments
This record represents the narrow concept of Malacothamnus fasciculatus following Morse (2023) with four infrataxa distinguished: var. catalinensis, var. fasciculatus, var. laxiflorus, and var. nesioticus. Morse (2023) recognizes M. arcuatus, M. fasciculatus, M. mendocinensis, and M. nuttallii as distinct species (and treats M. hallii as a variety, M. arcuatus var. elmeri). In contrast, M. arcuatus, M. hallii, M. mendocinensis, and M. nuttallii are included in M. fasciculatus by Kartesz (1994, 1999) and Flora of North America Editorial Committee (2015). Also differing, Slotta (2012) recognizes M. hallii as a distinct species, treats nuttalli as a variety (M. fasciculatus var. nuttallii) but does not mention M. arcuatus and M. mendocinensis.
