Well Steve, per our private
discussion as to the true identity of the elusive species P. mandaianum, or
hybrid P. X 'Mandaianum', the latter of which is pictured and described in
Exotica and Tropica (Graf), and other sources as well, Tom's reply of 'no such
name' is most interesting.
So can we call this plant
Philodendron hastatum 'Glaucophyllum'? It differs from the regular
ph. hastatum in blueish leaves.
The governing codes are
the International Code of Botanical Nomenclature for taxa and the International Code of
Nomenclature for Cultivated Plants for culta (cultivars). If a species name
is not published according to the ICBN rules, it is not accepted. To extablish
cultivar names, proper orthography has to be used. As in the above hybrid
P. X 'Mandaianum' can not be established, because Art. 13.3 of the
ICNCP does not permit the use of the multiplication sign (X) in a cultivar name.
If he correct cultivar name formulation should be P. 'Mandaianum', if
such a name has been established in the Aroid cultivar registry.
'Glaucophyllum' would be an acceptable cultivar name only if P.
glaucophyllum was published before 1 January 1959. If it was published after
this date (either validly or invalidly under the ICBN)), this Latin formulation
can not be used as a cultivar name and a name in a modern language must be
selected under the ICNCP and established in the Aroid cultivar

Mr Graf took peoples' names and wrote them
down, and as far as I know did not take it any further than that. In no way to
I criticize him, i think EXOTICA is the mother of the interest in RARE PLANTS
in the USA. I also knew immediately what you meant by phil glaucophyllum since
i had heard it applied to THAT PLANT for ages. When graf came here to
photograph some bamboo, we told him this name on it was just what it was being
called NOW, and we fully expected it to be a temporary name, and due to be
changed in the very near future, and he did not seem concerned, concerned ONLY
with getting the grove on film.
NOBODY worships accurate taxonomy more
than I do, by the way. My greatest contribution to it is removing wrong
labels, since i do not name species. i am relieved to report that this is NOT
MY JOB! I do use various punctuation marks to indicate a name in current usage
has not been thoroughly vetted. The one thing I do not do is go on the
warpath every time i see a wrong name, unless it is something like a person
putting a patent and a new name on a plant previously published by my good
self. because that is just plain ICKY.
And I will follow up on the
latest news in taxonomy and change my labels.
Of all the plants I grow,
i know least about the names of Aroids than all the others. I am totally
dependent on youse guys.
