ICBN Art. 7.11

[Hideki Nakai]

Dear Michael,

I think that this Art. and Ex. provide typification for its priority, nor
for valid publication.

> 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.

> In a perusal of several journals for new species publications, I see that

> 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...
