Welp…neither the Oncidium Sharry Baby x Tolumnia Jairak Firm nor the Tolumnia Jairak Firm x Oncidium Sharry Baby crosses progressed further than the swelling of the columns—all of their flowers that I tried pollinating have withered and fallen!
While slightly miffed, I didn’t come up entirely short—I made a couple of other attempts: Oncostele x Tolumnia and the other way around(Tolumnia as the seed parent, Oncostele as the pollen parent).

Tolumnia parent

Like the initial cross of Tolumnia x Sharry Baby, the flowers I tried pollinating on the Tolumnia didn’t progress past swelling of the column and withered away, but the Oncostele seems like it may be developing some capsules!
Potential capsule A

Potential capsule B—in addition to planning for a spare capsule, this was also an experiment on how long the window for pollination would stay open: the plant was knocked over and several flowers had their anther cap and pollinarium removed on the way down—this flower was pollinated 8 days after hitting the deck and losing its stuff! This may be entirely unremarkable, but I’ve been under the impression that, as a rule of thumb, as soon as a pollinarium is removed, dehiscence of the flower is soon to follow?

If these develop, I’d be curious to look inside of them but I’m keeping my expectations realistic!
