Ranunculus revision?
Jane McGary (Fri, 20 Jul 2007 08:44:57 PDT)

Jan Agoston's post seems to imply that the genus Ficaria as a split from
Ranunculus is a name used primarily by botanists in the former Soviet
sphere of influence. Am I understanding this correctly? (I hope so.) When I
Googled Ficaria verna and F. kochii, I found several scientific papers,
mostly having to do with medicinal compounds, using this name. It's
possible they were relying on Russian taxonomy, where we often find splits
that are not generally recognized elsewhere. SImilar disagreements exist in
Chinese and Japanese floras (e.g., Ohwi's Flora of Japan).

Someone once told me (I don't know whether this is true) that Soviet
botanists were encouraged by the government, their employer, to propose
numerous new taxa for ideological reasons. I recall that in linguistics
there were ideological pressures on academics to produce results that would
not have passed international peer review; perhaps the situation in botany
was similar. There's also a tendency in some areas that aren't controlled
so intensively to stress the uniqueness of the regional flora, perhaps
reflecting a theme of regional cultural uniqueness (and, presumably,
superiority); for instance, claims that a population of humans is
biologically different from other populations, or that its language is
unrelated to any other. Taxonomy (the "folk" kind, not the scientific kind,
but there's probably an intellectual connection) is in fact studied as part
of the subdisciplines of semantics and lexicography.

Those of you who are gardeners first and armchair taxonomists second (if at
all) might be asking a question or two about these names Ranunculus ficaria
and Ficaria verna.

I know I would have been, except that it just happens that I ran across a
discussion of these names recently and I now understand what, from a
taxonomic point of view, is happening.

Most of us, as gardeners, know about the rule of priority: basically, the
earliest validly published name is the one to use.

If (as it is) Ranunculus ficaria is a validly published name, and if (as it
is) the first validly published name for the species in question, what
happened to the rule of priority? How does Ranunculus ficaria become Ficaria
verna? If the first published species name was ficaria, wouldn't ficaria
trump verna?

It would, except for one of the basic principles of botanical nomenclature:
tautology in the genus and species names is not allowed. In other words, if
you establish a genus Ficaria, you cannot have a species in that genus named
ficaria. You then use the next validly published name in line, so-to-speak.

I have not seen a modern treatment of Ranunculus, but if a genus other than
Ficaria is used for the species in question, the species epithet goes back
to ficaria.
