some Tolumnia NOID in bloom

Good job! None of mine have rebloomed for me yet. They grow well and are on the reddish side. But no blooms.

There are a few hybrids in this genus which have been tissue reproduced , and are then sold under their registered names - usually ones which have been awarded. But generally it seems that are simply sold as Tolumnias. It is curious that the species - I have grown at least half a dozen different ones - all have very much smaller flowers. I wonder where the larger size comes from.

Agree with you on this. I see a gradual increase in the size over the years. may be crossed with a oncidium of some sort or may be because of polyploidy may be?.
