Make this distinction in your minds firm:
There are naturally occurring species and genera and then there are man-made
hybrids that involve species and other hybrids, sometimes across genera
lines. The rules for naming each type are different, although there is some
overlap.

Regarding the naming of multi-generic hybrids:
From my very old copy of "The Handbook on Orchid Nomenclature and
Registration"
the following are excepts from the International Code of Botanical
Nomenclature, 1988"

Article H.6
"The name of a hybrid genus (i.e. the name at the generic rank for a hybrid
between representatives of two or more genera) is a condensed formula or
equivalent to a condensed formula.

"Such name of a bigeneric hybrid is a condensed formula in which the names
adopted for the parent genera are combined into a single word, using the
first part or the whole of one, and the last part or the whole of the other
(but not the whole of both) and, if desirable, a connecting vowel.

"Such name of an intergeneric hybrid derived from four or more genera is
formed from the name of a person to which is added the termination -ara; no
such name may exceed eight syllables. Such a name is regarded as a
condensed formula.

"Such name of a trigeneric hybrid is EITHER (a) a condensed formula in which
the three names adopted for the parent genera are combined into a single
word not exceeding eight syllables, using the whole or first part of one,
followed by the whole or any part of another, followed by the whole or last
part of the third (but not the whole of all three) and, if desirable, one or
two connecting vowels, OR (b) a named formed like that of a hybrid genus
derived from four or more genera, i.e. from a personal name to which is
added the termination -ara.

I have published a nothogenra with the help of the RHS registrar.
Huntingtonara [Htg.] Paraphalaenopsis x Phalaenopsis x Renathera x Vandopsis

I had seedlings of (Ernestara Firestorm x Paraphalaenopsis Sunny) for sale
at one time. I had made this grex. None had bloomed and still haven't so
the actual grex remains unregistered. However, I was selling them and it
was causing confusion because no other hybrid made using all four genera had
ever been registered and there was no artificial genera name for this
grouping. So I didn't know what to print on the tags.

Anyway, my dog BamBam had just died and I asked Mr. Shaw if I could name
this new nothogenra Bambamara but he said it was unlikely the name would be
approved unless I could prove BamBam was a person or renown in the orchid
world. So I suggested either Huntingtonara, after Merritt Huntington or
Nortonara are HP Norton. I did not seek permission from either,and I think
that was a faux pas. Anyway, the committee approved Huntingtonara and it
was published in the New Orchid hybrid registration addendum in, I think,
January 2004. I suppose Merritt would have like this story, although I
never got around to telling it to him. He would have probably made some
sour comment about coming in second to a dead dog, and then his eyes would
twinkle as he watched my reaction to see if he had managed to get my goat.
I think he got a hoot out of collecting goats.

It is suppose to be impossible to cross Paraphals with Phals. I though
maybe I could do it by a less direct method. These seedlings grow as if
they know they can not exist. I am hoping to see at least one bloom one
day, but they may have other ideas. Since Merritt Huntington's recent
death, it has become even more important to me to see them flower.

Boy, the people creating all the multi-generic oncids really paid
attention
to that rule now didn't they? ;-)

In general though it seems that rule is commonly violated for hybrid genus
names (e.g. Lc, Blc, Ascda, etc...).
