  Anthurium cross pollination?
From: Don Martinson <llmen at wi.rr.com> on 2017.10.11 at 10:53:39(23798)
To what extent are members of the Anthurium Section Pachyneurium intrafertile? I grow both Anthurium schlechtendalii and Anthurium watermaliense, neither of which has ever set seed. This year, they bloomed at the same time and were right next to another. The schlechtendalii inflorescence faded and dried, while that of the watermaliense appears to POSSIBLY have been fertilized. So was I simply fortunate to have the watermaliense self pollinate, or is there any chance that they might have crossed? Photos of all below.

Dear Don: My breeding studies with Pachyneurium showed that all of the Central American species that we crossed would hybridize and this was true of a smaller
number of South American species that we tried to hybridize but there were many Central and South American attempts to cross with failure. It thus appears that these two areas were separated for a very long time.

Thank you, Tom. It will be interesting to see, if indeed these two species have crossed, what form the seedlings will take, considering the difference in morphology between the two. I imagine the ripening will take some time and unless they abort I will have more seed than I will have room to trial.

That said, if there is anyone who would be interested in trying some of the seed if it matures, please PM me at: llmen@wi.rr.com. They will be available gratis. The worst that could happen is that they could possibly be the straight species, A. watermaliense
