Paph. Armeni White

[gnathaniel]

Foliage markings aren't a good way to distinguish Fumi's Delight and its parent species, both armeniacum and micranthum can be pretty diverse and FDs are unsurprisingly all over the map in this regard. Doesn't one species have very finely toothed leaf edges and the other not? I don't recall which is which off the top of my head, but if armeniacum has teeth then their presence in this plant would indicate probable armeniacum ancestry, though absence doesn't necessarily indicate the reverse...

I think Rick's suggestion that this might not be F1 (armeniacum x micranthum) is spot-on, (FD x FD) progeny are more likely than F1 to favor one parent over another. A 2N armeniacum x 4N micranthum cross would also be somewhat micranthum-dominated. And as orchideya points out, the micranthum parent being eburneum and/or the armeniacum being markii could account for trait combinations not matching what we're used to seeing in FD. Some genes encode for visible traits while some affect expression of other genes in direct or indirect ways, and it's pretty much a given that distinct varieties or forms of a species have some genetic distinction from the general population.

Finally, there's an inherent problem in using online pictures to judge the range of how FD looks since these will heavily favor the 'good' ones that people want to show off. armeniacum's color is a major attractive feature sought by breeders of this cross, and if color expression relies on any of the same genes as staminode shape then there may be a hidden selection bias making FD flowers appear more armeniacum-dominant than they actually tend to be.

Wow, that was way longer than it needed to be but yeah, this is much more likely Fumi's Delight than straight micranthum...

I wouldn't say totally different, but rather very close actually.
The staminode on this one looks more "pinched" and many micranthum have such narrow (whether pinched or not) staminode, although not all of them.

FD can also have rather narrow staminode, but vast majority I've seen had much wider staminode.

Then, again, all this talk won't make it possible to ID your flower because of the variability within the species and hybrids.

All we can say is, whatever it is, the original tag saying Armeni White is not correct. That's about how far you can go with this.

I don't know.
Here is the regular micranthum that I bloomed back in 2012 ;

Staminode is totally different, no? But when I look at the leaves - they look identical to micranthum var eburneum that I got from Matt. Maybe it is a Fumi's Delight made with micranthum eburneum?
The flower fell off yesterday. I re-potted the plant into smaller containers since it was overpotted and runners connections rotted thrugh. Luckily all the fans have their own new roots, so I will wait for new blooms. We'll see if they will be white again.
