Well, good luck. 'aff' is the most appropriate way to label them.
we were having this discussion on another site recently. A lot of us (myself included) hybridize our own Anthuriums. Or grow out bench crosses to see what we get. I myself maintain a 1740 sq ft greenhouse which is its own little ecosystem. I have a stream and a pond in there, and many many tree frogs and insects. The mother tree frogs lay eggs in the cups of my bromeliads and the little baby tadpoles hatch out. They are drawn to the insects that come to the receptive Anthurium spadices, and sometimes they pollinate my plants when they are crawling all over them eating bugs.
When some of the spadices on my plants are receptive, I try and pollinate them myself with pollen from an Anthurium in a compatible section. And sometimes, I pollinate the same spadix with pollen from more than one species. This is heavily frowned upon by 'purists'. But this is my own personal slice of my hobby. I do not intend to try and name these hybrids or register them. I just intend to GROW them. And if they are nice plants, I will trade and sell them ( I have a nursery license). But I will never try and pass them off as anything that I know they are not....which is a lot different from some people out there who are looking to make a buck. If I trade or sell, it will be clearly stated that 'X Anthurium is the ovule parent and the potential pollen parents were Y, Z and whoever.
Case in point, I pollinated my Anthurium forgetii with pollen from my Warocqueanum, my crystallinum, my papillilaminum, and this hybrid shown here (besseae x magnificum).
I got a spadix of seeds and they are starting to pop out seedlings now. Who knows what they will turn out to look like? I actually can't wait to see. And if any are extra special nice, I will be growing those and likely give them some small silly name of my own. Nothing official.
I also recently pollinated my clarinervium with warocqueanum. But it also had its own pollen on the spadix (clarinervium is to a large degree one of the self pollinating plants). So those seeds may produce different looking seedlings.
I have had some people who believe themselves to be extremely 'expert' about aroids tell me that I am 'setting the hobby back' by not keeping strict records of my crosses and trying to be 'pure' about it. These people tend to be self righteous stuffed shirts that believe they are always right about every aspect of aroid culture.
I have had other people (mainly Australians) say that probably 95% of all the pollinations in Australia are bench crosses carried out by insect and animal agents, and that it is unavoidable, undocumented crosses WILL BE MADE! So you might as well make your own when you want to.
So there are 2 schools of thought.
I believe that if, to the best of your knowledge, you are marketing something as truly as you know it and not attempting to deceive, there is no problem with it. 'Aff' meaning of course 'having an affinity with'. Its a great descriptor.
That mother plant in that photo is DA BOMB. If your seedlings turn out anything similar, people will snap them up just because of their beauty and not care about the purity.
I myself LOVE hybrids. I also love the pure forms of plants, and I am lucky to have several very old very pure unadulterated species in my collection. But seeing new things is what makes the hobby interesting.
Just look at what happened to the Pachyneuriums....somehow, every unknown bird nest in the world is called A. hookeri....when in fact, A. hookeri is a rare plant. But it has become a catch all phrase for anything that is unidentified. That is sad. And its perpetuated by people selling unknown hybrids as hookeri. Either knowingly, or unknowingly.
