Nomenclator and Review of Phyllostegia (Lamiaceae)

Abstract

In 1987 Harold St. John published 93 names in Hawaiian Phyllostegia and 1 in Tonga; only 3 of them were accounted for in the most recent taxonomic revision of the Hawaiian species by Wagner et al. in 1990. The types of these names are analyzed, and the names are here incorporated into the current classification. Only five of the new Hawaiian species are here recognized as distinct (P kaalaensis, P. kahiliensis, P micrantha, P pilosa, and P warshaueri), and one of the new combinations is accepted here (P velutina), with the remainder here placed into the synonymy of other species. Five of the names were not validly published. The complete nomenclature of Phyllostegia at the species level and below is presented, including 181 names. A total of 32 Hawaiian Phyllostegia species are currently recognized, including the 5 recognized St. John species published in 1987 and 2 others, P haliakalae, resurrected from the synonymy of P mollis, and P renovans, discovered in 1989. The five Hawaiian species not treated in the 1990 revision are briefly characterized and discussed. Notes adding information on taxonomy, distribution, and population and conservation status not included in the recent treatment also are given. The genus also is known from Tahiti and Tonga, each with one species; the nomenclature for these two species is included, but they are not evaluated
