Kadenicarpus is a genus of flowering plants belonging to the family Cactaceae. It is native to eastern Mexico.[2] It has been synonymized with Turbinicarpus but molecular phylogenetic studies have supported its monophyly and separation from that genus.[3]

Taxonomy

The genus Kadenicarpus was first proposed by Alexander Doweld in 1998.[1] The name is in honour of Nikolai Nikolayevich Kaden (1914–1976), a Russian botanist.[4] Most subsequent treatments rejected Kadenicarpus, sinking it into a broadly circumscribed genus Turbinicarpus. The circumscription of Turbinicarpus has been described as "remarkably unstable", with species regularly transferred to other genera.[3] The broad circumscription of Turbinicarpus was recognized as polyphyletic by Hunt in 2016.[5] A phylogenetic study published in 2019 showed that a monophyletic Kadenicarpus was sister to a clade of Ariocarpus and a more narrowly circumscribed and so monophyletic Turbinicarpus:[3]
