I would think so. For example, Laelia anceps 'Mendenhall' AM/AOS (1991) was a spontaneous mutation of anceps 'Irwins' AM/AOS (1976). But more importantly, it's not that common to find a mutated mericlone, or else every vendor would do it for every clone, and it would not be such a story when one is found. To do so, someone would have to mericlone probably hundreds to thousands of a cultivar, and then test for polyploidy. As far as I can tell, this is done several ways:

1. By sight, judging from flower and plant traits, though this is not reliable, and someone should not just call a plant "4n" because they think it might be. For example, in Peter's (of Diamond Orchids) catalog, he describes "Cattleya Leolodiglossa 'Exotic Orchids mutant' x self" as "a selfing of my mutant, maybe 4n".
2. By crossing each mericlone suspected to be mutated with a known 4N plant, then crossing the progeny. If a clone is 4N, then crossed with a 4N, the progeny is 4N, and it should have no problem producing seeds. If a clone is 2N, then crossed with a 4N, the progeny is 3N, and it would usually produce not many if any seeds.
3. By using an expensive microscope, taking a number of cell samples, and counting the chromosomes. I believe it was said that the University of Hawaii took several hours to confirm just one tetraploid. These microscopes (e.g. Keyence BZ-X800) cost $50,000 and require expertise to use.

I think even if someone keeps a clonal name with a mutation, to use the same name back to back to describe both the original clone and the mutated clone would be downright confusing. An upstanding vendor should reasonably realize that this practice would be misleading, and improve his communication skills, in my opinion.

Note: I'm not an expert. Everything I said was from second-hand research online, which may not always be reliable. Take it with a grain of salt.

Yes it does.

I think any oversight of ploidy on the SVO list is simply due to the sheer amount of work it takes to write so many descriptions. Writing those lists takes a lot of time and patience. I suspect some of the finer details may get overlooked by accident.

Looking back at old emails (I'm a pack rat), looks like late June or early July for the Catasetinae release.

Hi, here is what I ordered:

SVO8052t - 3inch C. Howard's Delight (C. Interglossa f. coerulea 'Purple Tower' BM/JOGA x Lc. Elegans f. coerulea 'Leviathan') : 1
SVO9503 - 3inch C. NEW HYBRID (C. Mareeba Tiger 'SVO' x C. aclandiae 'Kathleen III' AM/AOS) : 1
SVO9563 - 3inch C. Leoloddiglossa (C. Leoloddiglossa 'SVO Speckled Blue' FCC/AOS x C. Leoloddiglossa 'Darkest Blue') : 1 :
SVO9414 - 3inch Slc. NEW HYBRID (Lc. Aussie Sunset 'Cosmic Fire' HCC/AOS x Slc. Virginia Dickey 'Diamond Orchids' AM/AOS) : 1 :

Finally got my order! East coast weather The hybrids look pretty much as expected. The species were surprising… the aurantiaca came with buds and the kerrii has a very promising looking sheath. The schilleriana is -tiny- , but healthy looking, it’s tickling my mounting instincts.

[orchidman77]

Very nice! I'm interested to see what the kerrii will do for you. I wasn't intrigued enough to buy one for myself, though, LOL!

I totally forgot to post mine - they only came in last week as we've had *very* consistently cold weather in CO. My plants all look great, and I'm most interested to see what the Princesse Clementine (dowiana x aclandiae) seedlings will look like when they bloom. I think the cross could be quite variable!
