Evan,
Yes, that is coarse perlite in the pots, which in the case of the brownish-maroon inflorescence, is a 4" pot. The other wee blooms are together in a 6" short pot. It is the spadix on the maroon one that is 2" long, not the spathe, which is about only 1/2 inch tall. The perlite should provide scale as to the size of the wee blooms in both cases.
For the record, these blooms are so small that my usual methods of collecting pollen won't serve, so what I've done is to take a small artist's brush and stick the bristled end down the throat of the spathe to get the pollen. In both cases, the pollen was whitish in color and was abundant enough for good attempts. All I need is take on both crosses, and I'll be off to the races!
