Higher Taxonomy
Family: DryopteridaceaeView DescriptionDichotomous Key

Habit: Perennial herb, in soil or rock crevices; rhizome generally short-creeping, suberect, or erect, scales large, generally tan to brown, generally uniformly colored. Leaf: generally tufted, 5--200+ cm, generally +- alike; stipe generally firm, base generally darker, with many vascular strands; blade 1--4-pinnate, often with scales, hair-like scales, hairs (except clear, needle-like hairs generally 0), or short-stalked glands on axes, between veins or not, veins free to netted; rachis, costa generally grooved adaxially. Sporangia: sori round, along veins; indusia peltate or round-reniform; spores elliptic, winged, ridged, or spiny, scar linear.
Genera In Family: +- 40--45 genera, > 1600 species: worldwide, especially tropics, wooded areas. Note: Based on molecular sequence data, Athyrium, Cystopteris, Woodsia removed to Woodsiaceae to preserve a monophyletic Dryopteridaceae.
Unabridged Note: Current data (as reported by Schuettpelz & Pryer and in papers cited therein) suggest that Wooodsiaceae is paraphyletic (with respect to Aspeniaceae, Blechnaceae, and Thelypteridaceae), yet are insufficient to resolve the questions of circumscription (too few taxa, not enough genes sampled). Alternative classifications that would preserve monophyly include recognition of several additional, small families (e.g., Cystopteridaceae, Athyriaceae, and others not in California, each comprising just a few genera) or lumping at least 4 currently recognized families, many of long-standing use and acceptance; a conservative and expedient course is taken for now (Smith et al. 2006), pending further work.

Genus: CyrtomiumView Description 

Common Name: HOLLY FERN
Habit: Rhizome short-creeping or ascending to suberect, stout. Leaf: stipe stout, base firm, scaly, ×-section with many +- round vascular strands in an arc; blade 1-pinnate, proximal pinnae not reduced, generally thick, leathery, veins regularly netted. Sporangia: sori round, in 2+ rows between pinna midrib, margin; indusium peltate, often ephemeral, sinus 0.
Species In Genus: +- 20 species: generally eastern Asia. Etymology: (Greek: arch, from pattern of netted veins)

Cyrtomium falcatum (L. f.) C. Presl
Habit: Rhizome scales large, light- to dark-brown, ovate, entire to jagged. Leaf: 30--80 cm; pinnae 4--10(12) pairs, 8--12 cm, often with 1 acroscopic lobe basally, margin thickened, +- entire to wavy or coarsely dentate, teeth 0 or < 10 mm, without bristle-like tips, adaxially bright green, shiny. Chromosomes: n=2n=123.
Ecology: Generally moist cliffs, banks, crevices; Elevation: < 900 m. Bioregional Distribution: NCoRO, SnJV, SCoRO, SCo, TR, PR (Santa Ana Mtns); Distribution Outside California: southeastern United States; native to eastern Asia; cultivated as ornamental. Note: Apogamous.
