Re: Nomenclature for Hosta

Hi All,

Bill I appreciate your input. Let me explain: The AHS is the International
Cultivar Registration Authority (ICRA) with Jim Wilkins being the assigned
Registrar. The nomenclature committee of the AHS sees to it that the AHS
naming rules follow the ICNCP. These rules were not "invented" by the AHS or
by George Schmid. They are based on the ICNCP (2004) which was adopted by
the International Union of Biological Sciences based on the work of the IUBS
Commission for the Nomenclature of Cultivated Plants: C.D. Brickell
(Commission Chairman), B.R. Baum, W.L.A. Hetterscheid, A.C. Leslie, J.
McNeill, P. Trehane, F. Vrugtman, and J.H. Wiersema. The AHS as the ICRA for
Hosta always has and still does strictly follow the rules of the ICNCP and
the ICBN. That is and has been the basis of the rules for AHS nomenclature
for many years now.

According to the ICNCP:

H. kyiosumiensis 'Nakafu' is against the rules of the ICNCP and cannot be
established.

The ICNCP allows the vernacular Japanese species name to be combined with
the descriptive cultivar name as:

H. 'Nakafu Kyiosumi' which can be established.

Since this is a cultivar, the name H. kyiosumiensis 'Nakafu' also cannot be
established under the ICBN, which has no jurisdiction because this culton
was not previously established as a taxon so has to be nomenclaturally
treated as a cultivar.

As chair of the AHS committee on classification and nomenclature, I am
asking AHS members and all others not to follow nomenclature advice posted
on the Internet. If you need help with nomenclature, please contact me
private at hostahill@bellsouth.net and I will be glad to advise on
nomenclature matters. If it is a matter of general interest the answer will
be posted on the forums.
