Abstract

Studies of Neotropical Celastraceae have revealed the identity of Maytenus calzadae (Lundell) J. S. Ma, first described as Euonymus calzadae Lundell. Analyses of the protologue and types identify M. calzadae as a species of Haydenoxylon M. P. Simmons and as conspecific with H. haberianum (Hammel) M. P. Simmons. Because the epithet of E. calzadae has priority, a new combination is necessary. Haydenoxylon calzadae (Lundell) Biral is published here.
