ISBN Art. 7.11

[Michael Vincent]

Dear Botanical TAXACOM members:

I wonder how people are interpreting Art. 7.11 of the ISBN (St. Louis
Code).  The text for this section is given below.
___________________________________________________________________
7.11. For purposes of priority (Art. 9.17 and 10.5), designation of a type
is achieved only if the type is definitely accepted as such by the
typifying author, if the type element is clearly indicated by direct
citation including the term "type" (typus) or an equivalent, and, on or
after 1 January 2001, if the typification statement includes the phrase
"here designated" (hic designatus) or an equivalent.

Ex. 6. Chlorosarcina Gerneck (1907) originally comprised two species, C.
minor and C. elegans. Vischer (1933) transferred the former to
Chlorosphaera G. A. Klebs and retained the latter in Chlorosarcina. He did
not, however, use the term "type" or an equivalent, so that his action does
not constitute typification of Chlorosarcina. The first to designate a
type, as "LT.", was Starr (in ING Card No. 16528, Nov 1962), who selected
Chlorosarcina elegans.

Ex. 7. The phrase "standard species" as used by Hitchcock & Green (in
Anon., Nomencl. Prop. Brit. Botanists: 110-199. 1929) is now treated as
equivalent to "type", and hence type designations in this work are acceptable.
__________________________________________________________________________

This seems pretty straight forward, and a literal interpretation would mean
that any new taxon would need the phrase "here designated" or equivalent to
be validly published.

In a perusal of several journals for new species publications, I see that
the phrase "here designated" is not included in any of the articles.  See
for example the most recent issue of Systematic Botany, in which new
species of Hymenophyllum, Paspalum, Tridens, and a new genus (Hekkingia)
are described, all without the "here designated" phrase.  Does this mean
all of these are invalid names?

Is anyone actually using the phrase when publishing new species?  I do see
it used when new lectotypifications are done...
