Kadenicarpus Doweld in Sukkulenty 1998(1): 22. 1998 sec. Vázquez-Sánchez & al. 2019



Systematics: Kadenicarpus is a monophyletic genus, strongly supported and is resolved as sister to the clade composed of Ariocarpus and Turbinicarpus (Vázquez-Sánchez & al. 2019). Anatomically it shares with Turbinicarpus the presence of prismatic crystals in the hypodermis and differs from it by the presence of xylem fibers in cortical bundles (De la Rosa-Tilapa & al. 2019). Three species and four subspecies are recognized, of which Kadenicarpus pseudomacrochele is the species with more morphological variation.
