Good! lindenii x warcewiczianum
:clap::clap::clap: you got it!
I made the cross, because in my mind lindenii and warscewiczianum (wallisii) are just forms or varieties of the same species. As a geneticist and a Plant Breeder I was curious to see what the outcome would be if you would cross the two together. In my paper (published in the Slipper Orchid Alliance Newsletter) I suggest to call them:
Phrag. lindenii var. lindenii and:
Phrag. lindenii var. wallisii
lindenii gets priority as it was described first. Also if you do it this way you don't have to deal with the warzcewiczii/warscewiczianum confusion, and the second entity (with the pouch) gets its name wallisii back (and this is the name it has had for over 100 years). Also for hybrid registration these two entities can be considered as separate entities.
my hypothesis was that the pouchless trait of lindenii is caused by one or multiple genes that are probably recessive, and if you cross it on to wallisii, the plants will gain back their pouches and look identical to wallisii. Now if I would self one of these wallisii x lindenii plants, I am guessing you may end up with some plants that will loose their pouch and look like lindenii again.
Here is a picture of Phrag. lindenii var lindenii:
By the way I named the cross Phrag. Pandora's Box, because I felt like I was opening up a "can of worms" and probalbly would create some confusion, as you won't be able to tell this hybrid apart from its parent wallisii.
