Steve:  I commented on the dots before seeing the pictures.  I thought you were talking about he dots on the petioles. The dots on the spadix are from an accumulation of resin.  The resin gets on the beetles and makes them sticky so that when they leave they can carry away the pollen which otherwise won’t stick to their bodies.

Someone tell me what is happening! 


This spathe of Philodendron sagittifolium opened this morning.  There is a second right beside it opening tonight.  These photos were taken at 9:30PM local time.  There is a slight smell of mint to the pheromone and if your hand is in front of the spathe, but not touching, you can feel the thermogenetic heat.  The red dots were not there this afternoon, but are clearly visible now.  I have no idea what these are!  Julius, Leland, Dr. Croat, anyone who knows!  What are these, what is the purpose?  Obviously no female flowers appear evident yet but I'll likely be up much of the night!
