Perennial, small, fleshy, generally glabrous; caudex generally underground, unbranched; roots glabrous, with bulblets or plantlets or not
Leaf generally 1 per caudex per year, divided into 2 facing parts with a common stalk; sterile part separated from fertile at to well above ground, blade simple to compound, veins free and forked (or netted, with included veinlets); fertile part bladeless, bearing sporangia, simple to compound
Sporangia dehiscent into 2 valves, ± 1 mm wide, thick-walled
Genera in family: 3 genera, 7085 species: ± worldwide, generally rare or overlooked. Fern-like plants with many traits of seed plants. Specimens must be carefully spread and pressed for identification; haploid generation underground, fleshy, non-green, associated with fungi.
Roots smooth, pale or cork-ridged, dark gray, without bulblets or plantlets
Leaf generally deciduous; bud glabrous or hairy; sterile part generally ± 13-pinnate (rarely simple or entire), linear to deltate, segments linear to oblong and midribbed or spoon- to wedge- or fan-shaped and not midribbed, veins free, forked, margins entire to dentate or irregularly cut; fertile part 13-pinnate, < to > sterile
Sporangia not sunken in axis; stalk 0 or short
Species in genus: 4050 species: generally temp to arctic or alpine
Etymology: (Greek: bunch of grapes, from clusters of sporangia)
Reference: [Wagner & Wagner 1983 Amer Fern J 73:5362]
Difficult, needing careful study; most species very uncommon, sporadic; good sampling of populations highly desirable in specimens
Horticultural information: TRY; DFCLT.
See the CNPS Inventory for information about endangerment and rarity.
Leaf: sterile part separated from fertile near middle, stalk very short to 0, blade deeply lobed to 2-pinnate, < 8 cm, < 5 cm wide, oblong to deltate, segments ± ascending, < 7 pairs, oblique-ovate to lanceolate-oblong, shiny, bright green, midribbed, margins entire to minutely crenate; fertile part 2-pinnate, 12 X sterile

B. lanceolatum (C.C. Gmel.) Angström (sterile leaf part triangular, fertile leaf part branched into 24 major axes near base) would key here, might be discovered in mtns of n CA. B. pumicola Coville, Oregon moonwort, of Crater Lake region, OR, has not been found in CA.
