[Aroid-l] Philodendron sagittifolium at female anthesis!

From: Steve at ExoticRainforest.com (ExoticRainforest) on 2008.06.07 at 12:46:57(17788) One big note: If you are not up to speed on this type of event there are two documents you need to read, both online: The first is Julius excellent by easy to grasp text on what is happening here: http://www.exoticrainforest.com/Natural%20and%20artificial%20pollination%20in%20aroids.html The second is a thread on UBC which has been going on for weeks. It offers an altrnative view as to what "additional" activities that haven't been fully explored may be involved. Since this spathe is not white, it should be less effect as an "infrared dish", but the idea is intriguing. http://www.ubcbotanicalgarden.org/forums/showthread.php?t8988 Part of it is bogus! I know, because I wrote it! But the basic thread is great food for thought! Marc Gibernau is beginning to investigate this idea. And Marc will be our guest at the 2008 IAS show! Be there! Steve Lucas +More www.ExoticRainforest.com OK, now Dr. Croat has explained the red dots are a resin for the pollinating beetle to get on their bodies and thus be able to pick up and carry pollen. During the night the thermogenic heat reduced as did the pheromone. By 1:30AM it was barely detectable. I forgot that the auto overhead watering system would kick in at 5:30AM! Didn't stay out long at 5:30 in the morning with the rain falling on my head. When that was done around 6:45 I tried to get back to taking photos. By the way, it is pretty much like being in the rain forest in your pajamas! Once the "rain" stopped this one was taken at 6:30AM. The spadix still appears almost like the 1:30AM shot. I think I notice is the color of red on the spathe itself just beneath the opening to the spadix has reduced in intensity. No female flowers appear present. This is obviously going to be a two day event, perhaps longer, with the species Philodendron sagittifolium. I'll be checking every few hours for activity. So a couple of observations: 1) the pheromone is not apparent this morning. 2) No thermogenic heat can be detected 3) The red at the lip of the spathe is reduced 4) No female flowers are present The spathe is obviously waiting on something to continue the cycle of reproduction. I'll guess we'll check every few hours and see what transpires. Now where did I put my Scarab Beetles? By the way, Julius, Leland, Marc, Ron, Denis, any of you that know about this activity please teach me! Steve Lucas @ 7;25AM Maybe 3 hours sleep! www.ExoticRainforest.com -------------- next part -------------- An HTML attachment was scrubbed...
