Oncidium ID Help - Orchid Board

I just recently got a new Oncidium but it didn't have a tag, so I was wondering if any one new what intergenic it is, or at least in the general direction. The closest I got was maybe something maybe in the colmonara realm, but the shape doesn't seem quite right. But im not very good at knowing the general qualities of intergenarics so I have no idea if my guesses are correct.

I would suggest not stressing over it. You've got an Oncidium alliance hybrid, with few exceptions, most of these mass produced clones prefer similar growing conditions.

There's really nothing in the photo that suggests this is definitely intergeneric, and I'm not even sure Colmanara is a thing anymore given the fact that Odontoglossums were mostly moved to Oncidium and similarly the "Miltonias" that were most often used in these crosses are now considered Oncidium or Miltoniopsis.

Welcome to the Orchid Board!

I agree with what signin wrote above. Based of DNA research, a lot of orchids have had their names changed from one genus to another. This has made many older names for intergeneric hybrids obsolete. People still use them, however.

Your plant has characteristics of many Oncidiums, and also plants now called Oncidium that used to be Odontoglossum. It might at one time have been called an Odontocidium.

These tend to be easy to grow in most homes. They like staying moist but not sopping wet. They like bright light but don't need direct sun all day long. They tend to flower from a nearly matured new growth. When bigger they may make nearly continuous cycles of growth through the year. They are best repotted, if needed, soon after flowering, when making new growth.

You can read more about caring for this type of orchid in this Orchid Board forum. Just pick a few threads and go to it.

I agree with everybody else. Your plant is now just an Oncidium. It looks to me like it may have some of what was once called Odontoglossum in its background back before all the name changes. If that is the case, it won't like hot temperatures, such as outdoors in the summer. I put most of my plants outside in the summer, but I have a few Oncidium hybrids that have a fair bit of formerly-odontoglossum in them, and I keep those inside all year, because they won't take the heat, but if you plan to grow yours as a houseplant all year, then you don't need to worry about that.

Thanks for every ones advice

. I realized I should have clarified more/I didn't quite use the write words, I was curious about the variety name (like Sharry Baby or Wildcat, or Sparkle Spire "Snowflake", etc) rather then the specific intergeneric. I more mentioned colmonara etc, to help narrow my search down a little bit.

There are so very many Oncidium hybrids, and a lot of them look so much alike that you can't possibly tell which is which. Your's is a pretty standard yellow Oncidium. There are hundreds that look just like it. I don't think there's even the slight chance that somebody will be able to look at that plant and tell you its name. You could try to find out who grew the plant to sell to the store to sell to you, and they may be able to tell you its name, but that's even a long shot. I'm sorry, but I'm afraid you will just never know its name. Just enjoy it for what it is. Give it your own name if you want. I do that with some of my NoIDs. It's kinda fun.

Also, Colmanara is now an obsolete name. It is now Miltonidium, and some Oncidiums were reclassified in the genus Gomesa, so those hybrids with Miltonia are now Gomonia.

I figured, thought it couldn't hurt to see if anyone knew for a best guess or otherwise though. Coming up with a name sounds fun, good idea. Thanks for the info about colmonara not being a thing any more. Maybe ill have to finally take the time learn more about all the names.
