Very pretty. You can see the ladies dancing.

Nice compact plant. I prefer that to the long fronds. Nice dancing ladies.

very nice

wow!

A pretty picture and a nice plant, as always. I noticed on IOSPE that this plant would be ID'd as O. concolor (see link below), and that according to Jay, at least, O. ottonis always has spotted sepals. Have a look and see what you think. Always enjoy your posts!

Here is a link that might be useful: Oncidium concolor

I agree - concolor. At a national exhibition in the USA or Europe there would probably be an expert taxonomist who could rectify these errors, but it's difficult to get people to come long distances here. We have to go mostly on what the grower says it is. There is an even worse case, which I will post shortly, where the label was completely wrong, not even the right genus.
