DEER FERN

Higher Taxonomy
Family: BlechnaceaeView DescriptionDichotomous Key

Common Name: DEER FERN FAMILY
Habit: Plants in soil [climbing]; rhizome short- to long-creeping to erect, scaly; new growth often +- red. Leaf: of 1 or 2 kinds, fertile, sterile; stipe in ×-section with vascular strands in circle; blade [(simple or 2-pinnate)] deeply pinnately lobed to 1-pinnate, pinnae deeply pinnately lobed or not, hairs generally 0; veins free or netted. Sporangia: sori linear to oblong, along veins parallel to nearest midrib; indusium shaped +- like sorus, opening towards nearest midrib; stalk cells in 2--3 rows; spores elliptic, scar linear.
Genera In Family: +- 9 genera, +- 250 species: worldwide, especially tropics; several species cultivated. Note: New classification badly needed, in which all genera but Woodwardia are placed under Blechnum or, preferably, +- 25 genera, including +- 10 new ones, are recognized.

Genus: BlechnumView Description 

Habit: Rhizome suberect [or long-creeping, climbing, or erect]. Leaf: of [+- 1] or 2 kinds, fertile > sterile, with much narrower pinnae or lobes; lower pinnae reduced or not; veins of sterile leaves free.
Species In Genus: > 200 species: worldwide, especially tropics, subtropics. Etymology: (Greek: ancient name for ferns)
Unabridged Note: Not monophyletic. Reclassification needed, in which Blechnum spicant probably will be treated in Struthiopteris.

Blechnum spicant (L.) Roth
NATIVE
Leaf: stipe short, base +- black, with persistent +- brown scales; sterile leaves forming rosette, spreading to arching, firm, deeply pinnately lobed to 1-pinnate, generally < 1 m, 2--10 cm wide; pinnae generally 20--80 pairs, 5--8 mm wide, entire to shallowly crenate, lower gradually reduced to semicircular lobes < 5 mm; fertile leaves appearing after sterile, in center of rosette, +- erect, 1-pinnate, > sterile, pinnae +- 2 mm wide, unlobed. Chromosomes: 2n=68.
Ecology: Shaded, neutral to acid moist areas; Elevation: +- 0--1500 m. Bioregional Distribution: NCo, NCoRO, n SNH, CCo, SnFrB; Distribution Outside California: to Alaska, Idaho; Europe, southwestern Asia, northern Africa. Note: Locally common.
Synonyms: Struthiopteris spicant (L.) Weiss
