Arum - naming a Group
Graham Rice (Mon, 09 Apr 2007 06:38:39 PDT)

Yes, quite right. As with the publication of any new name it requires
to be published in a reasonably accessible publication (including a
nursery catalogue) with, as John suggests, a description suitably
comprehensive to establish beyond reasonable doubt the
characteristics of the plants involved.

However, I'm not sure if the group names which have appeared in the
PlantFinder recently - Helleborus foetidus Wester Flisk Group, for
example - and which have often been coined by the RHS have all
actually been published in this way...

Nobody is disbarred from naming any botanical/horticultural entity so long
as the correct procedure is followed. So far as I'm aware (Graham Rice will
correct if I'm wrong) the procedure to publish a group name requires its
publication with a description of the characters it covers, preferably as
comprehensively as possible. An example of this is the publication of the
Galanthus nivalis Sandersii Group in our book 'Snowdrops', p.90-93, which I
know Diane can look up, where the yellow variants of Galanthus nivalis are
comprehensively discussed and the covering Group name instituted.

John Grimshaw described three instances where a Group name is used
for plants.

Who decides that a Group name is appropriate? In the case of a genus
with a regulating body, must it be done officially? Could a nursery
owner or an enthusiastic amateur decide to name one?
