GENUS INDEX

GENUS CODE: ASPLE
GENUS SCIENTIFIC: Asplenium
GENUS AUTHORITY: L.
GENUS COMMON: Spleenwort
GENUS SUMMARY: Asplenium is a large, nearly cosmopolitan genus of more than 720 species, with centers of diversity in the Appalachians, Central America mountains, Andes, and Himalayas.
GENUS IDENTIFICATION: Identification notes: Several of the more frequently encountered sterile hybrids are included in the key and treated fully below. Others may be recognized by intermediate morphology and usual co-occurrence with both parents.

FAMILY INDEX

FAMILY CODE: ASPLEN
FAMILY SCIENTIFIC: Aspleniaceae
FAMILY AUTHORITY: Frank 1877
FAMILY COMMON: Spleenwort Family
FAMILY SUMMARY: A family of a 2 genera and more than 720 species, of nearly cosmopolitan distribution. Murakami et al. (1999) conducted a molecular phylogenetic analysis of the Aspleniaceae, which confirmed that Camptosorus should be included in Asplenium, but suggested that Phyllitis is better separated from Asplenium. A later and more comprehensive study shows Phyllitis and Camptosorus to be deeply embedded in Asplenium (Schneider et al. 2004a), a conclusion followed here.

WEAKLEY FLORA

SCIENTIFIC NAME: Asplenium rhizophyllum
COMMON NAME: Walking Fern
SYNONYMY: [= Ar, C, FNA, Il, K, Pa, RAB, Tn, Va, W; = Camptosorus rhizophyllus (Linnaeus) Link - F, G, S, WV]
PHENOLOGY: May-Oct.
HABITAT: Moist outcrops of calcareous sedimentary, calcareous metamorphic, or mafic metamorphic rocks, such as limestone, dolostone, calcareous siltstone, amphibolite, mostly at low to moderate elevations, rarely to 1500 m or higher.
COMMENTS: S. QC, ON and se. MN south to c. GA, AL, MS, AR, OK, and IA. This species, sometimes placed in the genus Camptosorus because of its strikingly different morphology from (most) other Asplenium, is one of the diploid progenitors of the reticulately evolved Appalachian Asplenium complex. It is a parent of A. pinnatifidum and A. ebenoides (as well as other sterile hybrids), both of which have inherited a limited ability to produce plantlets at the attenuate leaf-tip. It is closely related to Asplenium sibiricum of e. Asia.
