Sceptridium

not marked as a favorite taxon Sceptridium lunarioides (Michaux) Holub. Common name: Winter Grapefern. Phenology: Jan-Apr.

TX and se. OK.

Glossary (beta!)

Section: Hiemobotrychium.

ID notes: The species is hard to spot, and all the more difficult to find because of its phenology; the leaves appear in late fall and die by early spring.

Origin/Endemic status: Endemic

Taxonomy Comments: Wagner (1992) proposed that Botrychium lunarioides be treated in a new monotypic section, Hiemobotrychium, of Botrychium, subgenus Sceptridium. Zhang et al. (2020) advocated its placement in a monotypic genus, Holubiella. Its apparent involvement in the generation of the allopolyploid species Sceptridium jenmanii seems a compelling reason to retain the species in Sceptridium.
