Summary Cantino, P. D. & Abu‐Asab, M. S.: A new look at the enigmatic genus Wenchengia (Labiatae). — Taxon 42: 339–344. 1993. — ISSN 0040–0262. The phylogenetic position of Wenchengia is considered in the light of new data on its pollen morphology and leaf epidermal anatomy. The pollen is tricolpate, tectate‐perforate, supra‐reticulate and has simple columellae. Leaves are hypostomatic, with mainly diacytic and diallelocytic stomata. Wenchengia appears to be most closely related to Ajuga, Cymaria , or Acrymia. A position close to Scutellaria, Tinnea , and Renschia is only slightly less parsimonious. Although Wenchengia was originally segregated as a monotypic subfamily, assignment to Ajugoideae or Scutellarioideae may be more consistent with a phylogenetic classification of the family.
