Botrychium neglectum Wood, Class Book Bot. ed. 2, 635. 1847. B. matricariaefolium of most American writers.

Leaves 2 -12 long, often very fleshy, erect, bright green, the common stalk relatively stout, nearly all above ground, devoid of sheathing bases of previous years; buds stout, the sporophyl and sterile blade both bent over at the tip, the latter enfolding the former. Sterile blade short-stalked, -2%' long, oblong, ovate or deltoid-ovate, acute, pinnate or deeply 2-pinnatifid, the segments oblong or ovate, obtuse, crenately lobed or divided, the divisions ovate-oblong; sporophyl 2-3-pinnate, with terete branches, the sporanges sessile or short-stalked.

In grassy woods and swamps. Nova Scotia to Maryland, west to South Dakota and Nebraska. Also in Washington and in Europe. May-June.

Leaves 6-20' long, usually robust, the common stalk short and under ground; bud pilose, the sporophyl and sterile blade bent down. Sterile blade usually long-stalked, commonly 2'-5' broad, subpentagonal, subter-nately 3-pinnatifid, or 3-pinnate below, the principal divisions stalked; ultimate segments obliquely ovate or oblong-lanceolate, acutish, the terminal ones elongate, 1/2-1' long; margins variously serrulate-dentate; sporophyl long-stalked, 3-4-pinnate, usually stout.

In moist woods and thickets, or open slopes, New Brunswick to Florida, Missouri and Minnesota. Very variable especially in New York and New England. Several forms have the divisions of the sterile blade longer-stalked and lax, with fewer and rounded segments, or the segments usually long and acute.

Leaves 8'-16' long, usually slender, the common stalk short, under ground; bud pilose, the sporophyl and sterile blade both bent down. Sterile blade long-stalked, subpentagonal, rarely more than 6' broad, subternately divided, the basal divisions unequally and broadly deltoid, decompound, the upper and secondary pinnae deltoid-lanceolate, pinnate, with laciniate or deeply cut pinnules, the ultimate divisions divergent, narrow and incised; sporophyl 2-4-pinnate, usually long-stalked.

In low woods and thickets or wooded slopes, Maine to Virginia, Kentucky and Indiana. Congested forms closely resemble the preceding.
