Kadenicarpus pseudomacrochele (Backeb.) Doweld is a species with wide morphological variation. The four subspecies share the presence of numerous tortuous, thin, non-sharp spines and a napiform root (Lüthy & Moser, 2002). The floral variation is the most diverse. Flowers are pale to dark pink in the subspecies pseudomacrochele and lausseri while flowers are yellow in the subspecies krainzianus and minimus, which led authors to suggesting that these subspecies should be recognized as species (Donati & Zanovello, 2004). A systematic study to elucidate the limits between taxa is therefore necessary. It is also worth mentioning that these subspecies are distributed in restricted habitats and that they are sought-after for horticultural purposes (Lüthy & Moser, 2002), so that a better understanding of species limits will also provide a rationale as to which taxa should have priority for conservation.A
