Asplenium hybrids
The fern genus Asplenium is well-known for its hybridization capacity, especially in temperate zones.
North American (or Appalachian) Asplenium Hybrid Complex
The Appalachian hybrid complex in Asplenium is a polyploid complex composed of 3 diploid species, 3 allotetraploid species formed by hybridisation and chromsome doubling from the former, and assorted diploid, triploid and tetraploid hybrids between the 6 species.
Parent Species (Diploids)
Hybrid Species (Tetraploids)
- Asplenium bradleyi (A. montanum × A. platyneuron; allotetraploid)
- Asplenium ebenoides (A. platyneuron × A. rhizophyllum; allotetraploid as species but most commonly diploid hybrid)
- Asplenium pinnatifidum (A. montanum × A. rhizophyllum; allotetraploid)
Other Hybrids
- Asplenium ×gravesii (A. bradleyi × A. pinnatifidum; allo-allotetraploid)
- Asplenium ×trudellii (A. montanum × A. pinnatifidum; allotriploid)
