Concept Reference
Help
Concept Reference: Kartesz, J.T. 1994. A synonymized checklist of the vascular flora of the United States, Canada, and Greenland. 2nd edition. 2 vols. Timber Press, Portland, OR.
Concept Reference Code: B94KAR01HQUS
Name Used in Concept Reference: Asplenium trichomanes-ramosum
Taxonomic Comments: Generally called 'Asplenium viride' in most floristic literature, but the Linnaean name 'Asplenium trichomanes-ramosum' has priority. However, the 1994 ICBN (Tokyo), Article 23, example 14, provides that the 'trichomanes' be dropped from this epithet, with the resulting name being 'Asplenium ramosum'; that name, in turn, was proposed for nomenclatural rejection (Zimmer & Greuter, Taxon 43: 303-304, 1994). The name Asplenium ramosum was rejected by the 2005 ICBN (Vienna). This reverts usage back to the next-oldest name, apparently 'Asplenium viride' again. LEM 18Jan95.
