Humidity low, water insufficient, roots unhealthy, water quality bad, over-fertilization - any or all of the above - possibly amplified by light too bright, temperatures too high or excessive air circulation.

I probably would have guessed Norito Hasegawa x roth just seeing this unfaded flower. Very nice outcome, especially a vigorous grower with those gorgeous leaves. Breeding material, indeed. I wonder how judges might react if fading is apparent, say with 2 flowers a couple weeks apart in age.

If that is typical, the proportions of that flower don't suggest a hybrid unless one parent has proportionally even longer narrower nearly horizontal petals... rothschildianum? I don't think so. If it is a large disjunct population it appears to be something new.

Even 1000 years ago those damn kids were tagging everything in site with gang signs.

This would be very interesting to breed with if it was symmetrical on both petals - get some pattern into Phrag hybrids. Truly an odd thing if it is stable but unilateral. Still, if it was my plant I'd self it and see what I got.

With the hard short leaves and broad petals, this has a fair chance to be tetraploid. Assuming it was not from very inbred stock to begin with that makes it a better than average candidate to produce vigorous seedlings from a selfing. I'm not usually a fan of selfing species, but I think this...

The third is particularly nice. What is the cross?

Experiences vary. USPS is the ONLY way I can possibly receive plants in good condition this time of year, unless I can arrange to take a day off and be there to receive the package from UPS or FedEx, and they actually deliver on the day the notifications say they will, and I check outside the...

Spider invasion!

I'd go with Ma Belle. Even if the green background is lost you might get a very bellatulum flower with a taller stem that isn't face-down in the dirt, but you should get some that are just about as green as the Ma Belle too. Second choice - vini Maudiae.

The intensely dark flowers that often result from multifloral x vini maudiae crosses strongly tend toward odd kinks and crinkles, and worse, that detract from the symmetry - more that non vini crosses. If they are perfect they can be spectacular, but the dark flowers probably have a limited...

To reiterate - it is not just etiquette, it is not just orchids, it is not just a matter of opinion. There are internationally recognized rules for naming cultivars, and cultivar names can be viewed as similar to trademarks and brand identification. Any deliberate circumvention of the rules is...

If you look at enough clones of both lowii and spicerianum you'll see a few that have some speckling in the lower part of the dorsal or along the center-line. I think this may be a happy reinforcement of a weakly expressed trait from both parents, or a loss of genetic suppression of ancestral...

The rules about naming cultivars come from an international agreement, International Code of Nomenclature for Cultivated Plants, maintained by the International Society for Horticultural Science. It isn't a matter of opinion. As I was taught, as long as a single owner has all divisions or...

That's a very nice example of the cross.

A great example of an impressive species. Love the long stem. I'd cross it with one of your Paph hainanensis just to make long-stemmed babies.

That is correct. This name was proposed for a new species, by Schoser, at a World Orchid Conference in 1978 but never followed up with a valid publication. Ultimately it was formally named for him in 1988.

Paph Deperle is a good example of a type that can change color fairly dramatically as flowers age, and confirmation to a lesser extent. Any flower does to some degree, so photo comparisons of flowers of different ages have to take that into account.

Naoki - It would depend on the type of sand, particle size, pH, etc. Roots or mycorrhizae can get some amount of anything that is there in the sand grains, not just phosphorus. Granite sand might supply enough iron or manganese to be useful but probably not enough of the nutrients needed above...

Hard to say it is not Clair de Lune, but fairly safe to say it is not Clair de Lune 'Edgard von Belle'. The dorsal is too round unless both flowers are very freshly open, the petals lack the curtisii influence, and the warty spots are too prominent to be typical. Hard to judge the size from...
