Welcome to TF! A U. jamesoniana grower - truly a rare individual. Feel free to join the other Utric growers in the
sticky at the top of the forum (especially if you want to share your growing approach/conditions - always curious what others do...).
On your pollination question:
- do you have 2 seed clones? I forget whether U. jamesoniana responds well to selfing but if you only have one clone then it's still worth a shot.
- are you familiar with the flower structure? Here's a
pic of a U. nelumbifolia flower (same structure - just much larger than U. jamesoniana). The four anthers containing the pollen (shaped somewhat like a butterfly in the pic) are just below the stigma (shaped like a flap). These structures are visible when you open the flower 'hinge'. To facilitate pollination, I'll often cut the flower at the hinge & remove the superfluous lower parts (trying to hold a tiny utric flower open & pollinate at the same time can be tough).
--- To pollinate, you want to move that pollen up onto the flap. Some people use a tiny painter's brush, some a toothpick. I usually use a flattened end of a paperclip - scoop up some pollen with the tiny shovel & place it on the flap.
Beware, that if do indeed succeed, the seed is incredibly small - here's
a pic of some on a 1 mm grid, and like most Orchidioides seed, doesn't stay viable for very long (& apparently
hates the postal service).
