Notes

The morphological variation of Rapicactus beguinii is the widest in the genus, which is why multiple species and subspecies have been proposed (Donati & Zanovello 2004). A systematic study is required that includes a morphological analysis, DNA sequences and environmental variables that allows a better understanding of the variation and that allows to establish interspecific limits.A
