The Humifusa clade represents a recent radiation that originated in the late Pliocene or early Pleistocene and consists of about 10 species widely distributed in North America from northern Mexico north to Ontario, Canada, and south to the Florida Keys. This clade likely originated in the edaphically subxeric regions of northern Mexico and the southwestern United States, and from there it later spread to the southeastern United States and ultimately produced a small radiation in the eastern United States. Hybridization among evolutionarily divergent diploid species of the southeastern (SE) and southwestern (SW) United States subclades led to the origin of many polyploid taxa, which today occupy about 75% of the distribution of the clade. Here we present a taxonomic revision of the SE subclade of the Humifusa clade and polyploid derivatives that commonly occur in the eastern United States (i.e., the O. humifusa complex). We recognize eight taxa: Opuntia abjecta, O. austrina, O. cespitosa, O. drummondii, O. humifusa, O. mesacantha subsp. mesacantha, O. mesacantha subsp. lata, and O. nemoralis, as well as the interclade allopolyploid, Opuntia ochrocentra, derived, in part, from a member of the O. humifusa complex. Diagnostic keys, descriptions, original photos, and distribution maps are provided for each taxon. Neotypes are designated for the names O. austrina (NY) and O. youngii (USF), and O. drummondii and O. tracyi are lectotypified from an illustration in Maund & Henslow and a specimen at NY, respectively.

“…A new forma of Opuntia was identified by us; it was named O. humifusa f. jeollaensis. It has phenotypic similarity to O. humifusa, but differs by having red centered yellow flowers and the presence of hard spines in the cladodes (Kim et al, 2014). The origin of this forma and its taxonomic position are not known, but it is widely cultivated in the Jeollabuk-do Province of Korea.…”

Although Opuntia species are of high agronomic value in Korea, the taxonomic position of Korean Opuntia species has never been investigated. The taxonomic position of Korean Opuntia spp. within the tribe Opuntieae was examined based on DNA sequence analysis of matK, trnL-F, atpB-rbcl, and ITS regions. The total amplified sequence length was 2977 bp; only 18 parsimonious informative sites were present, even though they belonged to different species. A phylogenetic tree using both the maximum likelihood method with 2000 bootstrap replications and Bayesian posterior probabilities was constructed. The new forma, Opuntia humifusa f. jeollaensis, used in this study was placed within the Macrocentra clade rather than the Humifusa clade. The genetic distance between O. humifusa f. jeollaenis and O. camanchica was the lowest among all Opuntia spp. analyzed in this study. Korean O. ficus-indica was genetically closer to O. engelmannii than to O. ficus-indica previously reported. Opuntia engelmannii and O. ficus-indica have been considered conspecific previously, and so it is likely that the Korean O. ficus-indica used in this study may be a relative of O. engelmannii or may have arisen from a lineage different to the O. ficus-indica used in the analysis.
