Confirm Onc. Twinkle? Also, mystery Onc.

[Leafmite]

The Oncidium family is very large and many look almost identical. It is impossible to know what you have unless it is confirmed by the vendor. I think it is very unfair that orchids are sold without labels but, unfortunately, it happens far too often.
Unless you plan to have your orchids judged, the only drawback of not having a name is if the orchid dies and you would really like to replace it. I had a favorite noID Dendrobium that was fussy about its roots and that the kids knocked over one too many times. I wish I could replace it but I have no idea what it was.
If it is important to you to have names for your orchids, you will need to start buying them from places that label them. Otherwise, just enjoy their beauty and realize that when you really like an orchid, the name doesn't matter.
