Evan,
Well, the Sauromatum bloom opened this morning in all its odoriferous glory, but the T. trilobatum also opened last night so they both were receptive to pollen at the same time. Looked at first like I was going to miss out until I checked one of my Pinellias and found that there was some fresh pollen available there. So I crossed Sauromatum and Pinellia while the Sauromatum bloom was at its stinkiest. I took pictures to show the abundance of flies on it; when I cut open the bulbous area to reveal the female flowers, a horde of flies rushed out of the opening. With pollen-laden brush in hand, i anointed the pistils - twice!
Now all is in the hands of the Goddess of Blessed Pollination - tomorrow I'll have pollen on Sauromatum and a second bloom of T. trilobatum in a day or so to receive it.
