Glossary (beta!)

Origin/Endemic status: Native

Taxonomy Comments: 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 ruprechtii Kurata of e. Asia.
