Monographs Details: Mazus celsioides Hand.-Mazz.
Authority: Li, Hui-Lin. 1954. The Genus Mazus (Scrophulariaceae).
Discussion:According to Handel-Mazzetti, this is a tall, robust plant very closely related to Mazus caducifer Hance. From the description, it can be distinguished from the latter notably in the opposite leaves with the basal part of the blade pinnatifid.
