  Anthurium scherzerianum x andreanum?
From: <pbunch at cox.net> on 2009.05.26 at 16:23:51(19367)
Will Anthurium scherzerianum and A. andreanum hybridize. If so are the offspring fertile?

Dear Phil:

It would be unlikely that you could hybridize these two. They are in
different sections, Porphyrochitonium vs. Calomystrium.

Apparently not, different sections. HEL

Dear Phil,

You may want to check Steve Lucas' web site, he has EXTENSIVE information on Anthurium pollination. 
I do not believe that these two species you mention can or will hybridize, they are only distantly related (see Deni Bown`s wonderful book "Aroida, Plants of the Arum Family", pg. 207.
In your other note you ask if you can self pollinate A. scherzerianum.  Only if you have two blooms at different stages of development, as the cycle is as follows---the stigmas/female flowers become receptive after the spathe opens.  You`ll see tiny drops of moisture at the tip of each stigma indicating that the spadix is at female anthesis/receptive.  This is the stage at which you can apply pollen collected from ANOTHER, older bloom to these receptive stigmas.  After a few days/one day, these will dry up, and later on the spadix will start producing pollen along its length maybe starting from the top, working its way down to the bottom over several days, or the other way around depending on grouping/species.  This is the male anthesis.  If the female flowers were not fertilized before the male anthesis, the whole bloom will now abort.   In certain species of aroidd, viable seeds may be produced WITHOUT irect pollination, these will be clones of the mother-plant so keep your fingers crossed.
Good luck.  Check out Steve Lucas' site.

Indeed, the sections are distant within the Anthurium genus, but for exampl e
A. macrolobum is a hybrid of two species belonging to different section s
(A. pedatoradiatum from the section Schizoplacium A. clarinervium from the
section Cardiolonchium)

Dear Marek:

While it is true that the species making that hybrid were theoretically un related it is also to true that Mexican species are very different and perh aps not even related to the sections to which they are ascribed. Most seem to hybridize. That is not true elsewhere.
