Content

Notes

According to the phylogenetic study of Vázquez-Sánchez & al. (2019), Turbinicarpus rioverdensis Gerhart Frank is more closely related to T. swobodae Diers and T. valdezianus (H.Moeller) Glass & R.A.Foster, than to T. schmiedickeanus (Boed.) Buxb. & Backeb., in which it used to be included as subspecis (Hunt 2006). The spines of T. rioverdensis and T. schmiedickeanus are transversely cut by deep fissures that also involve the underneath layers. However, the stems of T. rioverdensis show periclinal epidermal wall type nipple and closed-type undulated-shape anticlinal epidermal walls, characters absent in T. schmiedckeanus.A
