Correspondence 1 indicates, with reference to Kartesz & Gandhi (1991. Phytologia 70:196-197), that for The Jepson Manual [Ed. 2] Athyrium alpestre var. americanum Butters is to be treated as an illegitimate name for Athyrium distentifolium Opiz var. americanum (Butters) Cronquist, essentially because Athyrium alpestre Clairv. (1811) is a later synonym of Athyrium filix-femina, and because Athyrium alpestre Milde (1867), based on the nomenclaturally superfluous Aspidium alpestre Hoppe (1805), is a later homonym [and therefore illegitimate]. Correspondence 1 also indicates that some (e.g., Lellinger, Tryon) have regarded, in perhaps an equally reasonable interpretation, the de Clairville name as published in a non-technical work (according to Tryon, in a pers. comm. to Lellinger, it is "an excursion flora in which the introduction states that it is not a technical work"), and hence not validly published [an interpretation that would render Athyrium alpestre Milde legitimate, in that it would no longer be a later homonym], but that according to Art. 29.4, ICBN [1988 Code; Art. 30.3 in the 2000 or St. Louis Code] publication in "trade catalogues or non-scientific newspapers" on or after 1 January 1953 does not constitute effective publication, so that publication in such literature before this date does [which renders Athyrium alpestre Milde a later homonym and therefore illegitimate since the earlier homonym, Athyrium alpestre Clairv., was published before the effective date of the Article that otherwise would have rendered it illegitimate].
