Wow, that's outstanding! I'm extremely interested in seeing how the bloom looks when opened (from both front and side), and especially if the bloom produces pollen at male anthesis. If you can get pictures of all that, plus one of the whole plant overall, I'd be very grateful. It might answer a few questions for me.
Also, if you happen to have any Caladiums in bloom at this time and would like to try a little experiment, let me know. I'm thinking about doing a cross vicariously, crossing the lindenii and a regular Caladium. It is exactly what I would try if I had the plants here with me!
