Ferns, terrestrial. Rhizome robust and short, erect or creeping, dictyostelic, covered with ovate-lanceolate to lanceolate scales. Fronds tufted or distant, dimorphic. Sterile lamina pinnatifid to bipinnatifid, green, deltoid-ovate, elliptic-lanceolate, or oblanceolate, papery or thinly papery; pinnae alternate, sessile or adnate, linear-lanceolate to narrowly elliptic, undulate or pinnatifid; pinnules hemielliptic-oblong, entire or subserrate with few teeth; veins free, pinnate or anastomosing, without included veinlets. Fertile lamina pinnate or bipinnate, elliptic to linear; pinnae or pinnules much inrolled, dull purple to dark brown, cylindrical or globose; veins free, pinnate or furcate. Sori round, indusiate or exindusiate; sporangia long-stalked, annulus a longitudinal row consisting of 3640 thickly walled cells; spores monolete, with perispore transparent, membranous, with a few folds.
Three (or four) genera: distributed in the temperate zone of the northern hemisphere and Mexico; two (or three) genera in China.

Plants medium-sized. Rhizome long-creeping, dark brown, covered with brown scales. Fronds distant. Sterile lamina pinnate, green, ovate-triangular, papery, both surfaces glabrous, with white long filiform hairs only on rachis and costae; pinnae narrowly elliptic, margin shallowly lobed, basal 1 or 2 pairs shortly stalked, adnate to rachis; rachis always with narrow wings; veins obvious, anastomosing with hexagonal areoles, without included veinlets. Fertile lamina bipinnate, much contracted; pinnae linear, shortly stalked, much oblique; pinnules much inrolled into small spheres, subopposite, separate from each other.

荚果蕨属 jia guo jue shu
Rhizome robust, erect or oblique, covered with brown lanceolate scales. Fronds tufted or approximate. Sterile lamina bipinnatifid and apex pinnatifid, ovate-lanceolate, elliptic-lanceolate, or oblanceolate, papery or thinly papery, nearly glabrous or with few hairs or scales on rachis and costae; pinnae alternate, sessile, narrowly lanceolate, pinnatifid to 1/2; lobes oblique, oblong to elliptic, subentire or subserrate; veins free, pinnate, veinlets reaching lamina margin. Fertile lamina smaller than sterile lamina; lamina pinnate, elliptic to broadly oblanceolate; pinnae linear, alternate, subsessile, much inrolled into brown cylinders, concealing sori. Sori globose, with raised receptacles, borne at ends of veinlets, indusiate or exindusiate; sporangia spheroidal, slender-stalked, annulus longitudinal, consisting of ca. 40 thickly walled cells; spores elliptic, perispore transparent, slightly folded. n = 40.
Three species: distributed in the temperate zone of northern hemisphere; three species in China.
Because Matteuccia is paraphyletic, Pentarhizidium is better segregated from it.
