Higher Taxonomy
Family: ThelypteridaceaeView Description 

Habit: Plants generally in soil; rhizome short- to long-creeping, prostrate to erect, [trunk-like], scales generally hairy, +- brown. Leaf: stipe ×-section at base with 2 crescent-shaped vascular strands fusing into 1 U-shaped strand distally; blade 1[2]-pinnate, generally with needle-like, clear hairs on axes and/or between veins; rachis, costae generally grooved adaxially except between axes; veins free or in regular, net-like pattern. Sporangia: sori on veins, generally round; indusia reniform or round-reniform [0]; stalk cells in 3 rows; spores generally elliptic, scar generally linear.
Genera In Family: 1 genus (5--32 genera), +- 1000 species: worldwide, especially tropics; several cultivated.

Genus: ThelypterisView DescriptionDichotomous Key

Leaf: pinnae entire to generally deeply lobed, veins generally not forked.
Etymology: (Greek: female fern; ancient name for delicate fern)

Thelypteris puberula (Baker) C.V. Morton var. sonorensis A.R. Sm.
Habit: Rhizome creeping, 3--8 mm wide; evergreen. Leaf: +- regularly spaced, generally 50--120 cm, 15--30 cm wide; stipe scales lanceolate, brown, not persistent; blade thick, abaxially +- nonglandular, +- densely hairy on axes, veins, and between veins; pinnae deeply lobed, lobes narrowly oblong, entire. Sporangia: sori small, round; indusia densely hairy.
Ecology: Along streams, seepage areas; Elevation: 50--800 m. Bioregional Distribution: SCo, WTR, SnGb, SnJt; Distribution Outside California: to Arizona, southern Mexico. Note: Rarely cultivated in southern California. 1 other var., Thelypteris puberula var. puberula, Mexico to Costa Rica.
Unabridged Note: Christella puberula A. Löve & D. Löve, published [1977 Taxon 26:326] for the nominate element of Thelypteris puberula, may reflect a superior classification, but a combination that would include var. sonorensis within Christella puberula has not been made. Recent molecular evidence [A.R. Smith & R.B. Cranfill 2002 Taxon 56:1037--1050] suggests that Christella itself may be polyphyletic and possibly not separable from Cyclosorus s.l. Some combinations of supposed Christella taxa within Cyclosorus, including "Cyclosorus puberulus," have not yet been made.
