Galapagos Species Database

Taxon category: Accepted

Note: Plumularia sinuosa, originally described from the Galapagos and Mexico, is considered a questionable synonym of P. floridana. Collected from Salinas, Ecuador, and various Galapagos islands, its molecular data differ from Atlantic and Pacific populations. Cryptic diversity suggests it may represent different species, but the name P. floridana is retained for Ecuador material (Calder, et al., 2021). Syn.: Plumularia alicia Torrey, 1902, Plumularia alicia var. minuta Billard, 1927, Plumularia indica Mammen, 1965, Plumularia pennycuikae Millard & Bouillon, 1973 (Horton et al., 2021).

Origin: Cryptogenic

IUCN Red List Category: Not evaluated
