Botrychium oneidense

(Gilbert) House

Amer. Midl. Naturalist 7: 126. 1905.

Warren H. Wagner Jr., Florence S. Wagner
Common names: Blunt-lobed grapefern botryche d'oneida
Basionym: Botrychium ternatum var. oneidense Gilbert Fern Bull. 9: 27. 1901
Synonyms: Botrychium dissectum var. oneidense (Gilbert) Farwell Botrychium multifidum var. oneidense (Gilbert) Farwell
Treatment appears in FNA Volume 2.

Trophophore stalk 2–15 cm, 1.5–2.5 times length of blade rachis; blade dull bluish green, ± plane, 2–3-pinnate, to 15 × 20 cm, ± leathery. Pinnae to 5 pairs, usually remote, horizontal to ascending, distance between 1st and 2d pinnae not or slightly more than between 2d and 3d pairs, undivided except in proximal 2/3–3/4. Pinnules obliquely ovate, margins finely crenulate to denticulate, apex rounded to acute, venation pinnate. Sporophores 2–3-pinnate, 1.5–2.5 times length of trophophore. 2n =90.


Phenology: Leaves green over winter, sporophores seasonal, new leaves appearing in spring.
Habitat: In moist, shady, acidic woods and swamps
Elevation: 0–1200 m

Discussion

Botrychium oneidense commonly occurs with B. dissectum and B. multifidum. Young individuals of both may resemble B. oneidense (W.H. Wagner Jr. 1961b).
