| description | Background and Aims: Hedwigia integrifolia is still conflated with Hedwigidium imberbe, despite previous distinction of these two species. This paper offers clarification of the taxonomic status of Hedwigia integrifolia, as a synonym of H. filiformis. The latter name is re-established only for the species characterized by filamentous pseudoparaphyllia, leaf cells with peltate papillae, and perichaetial leaves ciliate. Methods: Protologues, specimens of Hedwigia worldwide from several herbaria, and personal collections were studied to evaluate the taxonomic and nomenclatural status of H. integrifolia, along with the similar species Hedwigia filiformis. Anatomical observations were recorded of pseudoparaphyllia, leaf cell papillae, and capsule neck stomata. Key results: My examination of numerous Hedwigia specimens worldwide led to the conclusion that Hedwigia integrifolia is a heterotypic synonym of Hedwigia filiformis. For the correct identification of Hedwigia filiformis, a morphological description and illustrations are provided for this species, so far known to occur in Canada, the USA, Mexico, Italy, Japan and South Korea.Conclusions: Hedwigia filiformis differs from other species in Hedwigia mostly by its slender sympodial branches, short ovate leaves with revolute margins, the very short hyaline leaf acumina, and the short elliptical apical cell. |

Antecedentes y Objetivos: Hedwigia integrifolia todavía es confundida con Hedwigidium imberbe, a pesar de aclaración previa. En este trabajo se clarifica el estado taxonómico de Hedwigia integrifolia como un sinónimo de H. filiformis. Este último nombre es re-establecido únicamente para la especie caracterizada por los pseudoparafilios filamentosos y papilosos, las células foliares con papilas ramificadas y las hojas periqueciales ciliadas. Métodos: Se estudiaron los protólogos, especímenes de Hedwigia en varios herbarios y colecciones personales para evaluar la taxonomía y nomenclatura de H. integrifolia y la especie similar Hedwigia filiformis. Las cápsulas y tallos con hojas se estudiaron anatómicamente para observar los pseudoparafilios, las papilas de las células foliares y los estomas de las cápsulas. Resultados clave: El examen de numerosos especímenes de Hedwigia lleva a la conclusión que Hedwigia integrifolia es un sinónimo heterotípico de Hedwigia filiformis. Para la identificación correcta de Hedwigia filiformis, se proveen una descripción e ilustraciones de esta especie, por ahora conocida de Canadá, los Estados Unidos de América, México, Italia, Japón y Corea del Sur.Conclusiones: Hedwigia filiformis difiere de otras especies de Hedwigia más notablemente por las ramas simpodiales delgadas, las hojas ovaladas cortas con márgenes revolutos, los ápices foliares hialinos muy cortos y la célula apical elíptica.
