Summary
This Hawaiian taxon is documented with two described varieties, var. lanaiense and var. wahiawaensis; var. lanaiense has the basionym Labordia tinifolia var. lanaiensis with the Lana‘i holotype collected in July 1870 by W. Hillebrand, and var. wahiawaensis has the basionym Labordia tinifolia var. wahiaensis from Kaua‘i Wahiawa Valley, collected April 29, 1980 (S. Perlman 500), with holotype [BISH] and isotypes [BISH!]; notes indicate a complex nomenclatural history with multiple isonyms and author combinations for the species, including use of Labordia tinifolia basionyms for the varieties.
Two described varieties reflect island provenance, with typification anchored by Lana‘i and Kaua‘i Wahiawa Valley holotypes and isotypes, underscoring taxonomic history and classification details.
