That seems like a lot of questions. As a general
principle, if it has a different position, rank, type,
or (really different) spelling it will be a different
name. If it has the same position, rank, type and
(just about the same) spelling it will be just the
one name; spelling variations will not come into
As to when a name at a different rank has a different
epithet than a name for the same taxon at another
rank (with the same type), there are several examples
in the /ICNafp/ following Art. 11.2 (at
This may be for several reasons. Thamas Lammers once
commented on this list:
"The one time I excercised this option myself, I did
so to prevent the existence in a small endemic
Hawaiian genus of both a "/parvifolia/" and a
"/parviflora/." I thought the confusion avoided was
worth violating a recommendation."
And to confirm, yes, /Caryophyllaceae/ Juss. (1789) and
/Caryophylloideae/ Arn. (1832) (at different ranks) are
different names, with different authors, and different dates
(but with the same type). But /Xylomataceae/ and
'/Xylomaceae/' (at the same rank) is just the one name, as
is /Cyperaceae/ and 'ordo /Cyperoideae/' (equally at the same
rank); Art. 18 Ex. 4 (at

> OK, thanks! Yeah, I had assumed that replacement names were of course among them (same in zoology). But I wasn't sure if your fourth type was a "thing" in the non-zoological context.
> But I'm curious about the third option; when a name is moved to a different rank its epithet may change but its type does not. Can you provide an example? And does this include any rank change (e.g., variety to subspecies, or subspecies to species)? Or only for uninominals (like subfamily to family)?
> Again this may be semantics, and it may be a(nother) difference beteen ICZN-land and ICNafp-space, but it's not clear whether a change in orthography necessarily represents a "different" name, or the "same" name with different spelling. In my way of thinking (perhaps not shared by many/most zoologists?), the family name "Labridae" is the "same" name as its subfamily counterpart ("Labrinae") -- so I wouldn't count this in the same category as replacement names or other cases where two different epithets (with different protologues and authors) share the same name-bearing type.
> I guess my (informal) thinking is that when two text-strings share the same type, authorship and protologue, they are the "same" name even if they differ in exact orthography. Of course, in my zoological perspective this also includes alternate combinations (with the "name" being the epithet), but I'm also thinking of uninominals like the family/subfamily example.
