Not a yellow picotee but a very tiny yellow band around the leaf. Leaves are very smooth too.
Another test is to break a leaf in half. If there are some fibers on the cut, it is not a sanderianum. sanderianum is possibly the most faked orchid plant. I will try to post a picture of mines.
For delenatii dünkel some have a magenta margin some do not. All of the original plants are very hard to grow. They have been collected 10 years ago but they are terribly slow growers.
Many paphiopedilum plants seedlings are misidentified. Growers travel around the world and buy plants here and there. They buy a lot from the Netherlands and Taiwan, and resell the plants. Both places are not reliable to trust them without flowering the plants.




I will just be patient, thank you, veeerrrry very patient!

Looks happy!
