Miniature Genus ID please
 

anyone know what Genus this is? I believe it is mostlikely a hybrid, I know i've seen it many times it just won't come off the tip of my tongue.


It is about 5" tall with a bunch of tiny little white blooms.

Also that Dend. I believe its a hybrid as well I just need to confirm. Anything helps

The flowers aren't very clear in the photo but the white could be Onc. Twinkle or a similar hybrid like Tsiku Marguerite.

The Den. may be a hybrid, but would be hard to distinguish from Den. bigibbum or Den. phalaenopsis species.

Yes, probably oncidium Twinkle and most likely a hybrid den Phal. Difficult to id absolutely.

indeed that helps a little, thanks!!! I work for a non profit instutution and need to do some inventories of the plant collection.

Can you post a clearer picture of the miniature? I think it's a miniature Dendrobium and not an Oncidium at all.

I agree that the other plant is probably a Dendrobium phalaenopsis hybrid.

The plant with white flowers has a classic Oncidium look to it: compressed pseudobulbs with long leaves coming from the sides and top. a long arching inflorescence coming from the base of the pseudobulb but emerging in the groove of a lateral leaf.

That is a good point that I hadn't considered, but I don't think I see even a hint of a callus in the flowers. That would be problematic for an Oncidium.

The white flowers aren't in focus enough for me to see any detail at all.

Orchidists use colloquially the term Oncidium to refer to any of the genera or nothogenera in the Oncidium alliance (horticultural term) / Oncidiinae subtribe (taxonomical term.)

I agree that the quality is poor. Perhaps I'm experiencing too much confirmation bias.

I have a Oncidium cheirophorum, one of the parent plants of twinkle. My cheirophorum flowers look very much like this, though they are yellow. I also have Tsiku Marguerite, very similar except it is a taller plant, maybe the other parent plant of Twinkle? The cheirophorum is small, 5 inches if that and I've had this plant several years. This looks more like a twinkle in my opinion. Is there an alba form of cheirophorum?

A better picture would be helpful.
