I realize this is a very old subject and the demand as well as high prices for Anthurium jenamnii has long since ended. But on the internet you will still find many pages that incorrectly indicate Anthurium jenamnii is a species (or man-made hybrid) other than the one known to science. I've spent almost two years researching this species with aroid botanists from Europe including Dr. David Scherbierich of France and Dr. Tom Croat of the Missouri Botanical Garden as well as noted aroid expert Joep Moonen from French Guiana where the species is relatively common. If you are interested in seeing the real species Anthurium jenamanii you just might find this link useful since it does not produce a reddish leaf: http://www.exoticrainforest.com/Anthurium jenmanii pc.html This information has been reviewd by at least three aroid botanists.
Good to know what we are growing. This one came as jenmanii, but you have convinced me, probably bonplandii subsp. guayanum! Still a nice plant.
Anthurium bonplandii subsp. guananum is more beautiful (in my opinion) than Anthurium jenamnii and certainly is rarer in nature according to the botanists. My personal goal is simply to understand which plants are the ones described to science and personally I'd say your plant is certainly A. bonplanii guayanum. It looks like you are doing a great job of growing it!
No Mike, I got it years ago from Fred Moody, who had his for years. Here is how it looked two years ago. When it divided in two I put one in the garden, but unfortunately the red new leaf is a beacon for snails.
