Novelties in Asian Mitreola (Loganiaceae): M. capitata, a new species from Vietnam, and lectotypification of M. spathulifolia

A new species of Mitreola, M. capitata, has been discovered in Phong Nha-Ke Bang National Park, Vietnam, distinguished by its unique leaf-rosette habit and compact, head-like inflorescence with dense indumentum. This discovery was made during a 2022 botanical survey and is closely related to M. spathulifolia but differs in key morphological traits such as smaller leaves, denser inflorescence, shorter pedicel, hairy calyx, and smaller capsule. Additionally, the study revises the typification of M. spathulifolia by selecting a lectotype, clarifying its taxonomic status.
