Longifolia is part of section Foliosa, not Orchidioides.
Everything has a reason, whether big or small. Never underestimate the power of what is or is not.
There is far more to everything than meets the eye.
One of the nice things about 'most' of the Orchidioides is that they are usually easy to kill. Because of this, I don't need to freak out when roots like this happen to wander next door
As long as I keep plants that have noticeably different leaf shapes next to each other, the invasions aren't an issue. I either treat the upstarts like a mini-propagation when I do divisions or I simply pluck the different leaves out and soon, the invader is dead. I currently have some U. 'Jitka' in a pot of U. quelchii that is just waiting for division time to be separated. I also have some U. nephrophylla in a pot of U. quelchii - & that will never come out (that accident apparently came from the European supplier mixed together as U. nephrophylla has never been near that pot - nor even in that tank). U. longifolia (& probably other foliosa-section species) would also never come out either - I think they can completely regenerate from single cells (after flame sterilization) ...
Ok.. that means I really need to find my very first orchidiodes and try to prove again my climate is for them, well, since we have like 8 species around I really would like to try and grow them, but have never found them for sale anywhere.
Have you guys done tissue culture with them? if I get some I would definitely want to try it!
admonishments of more veteran growers to "kill them while you can". Imo, the larger Orchidioides hit the sweet spot - healthy robust growth when given the right conditions but also reasonably easy to control.
** even now, the U. quelchii that I mentioned in another post--- it's completely impossible to rid that pot of the U. nephrophylla*** that it came with. I cannot even make a division without contamination - so I'm being forced to start over from small root cuttings. I've got a flowering-sized, very healthy plant (& rare clone) that I've got to get rid of without even getting to keep any of the nice-sized divisions that could flower quickly.
*** don't get me wrong about U. nephrophylla - I love the species - it's one of my favorites. After cultivating several clones, I have one that is very robust & free flowering that I keep upstairs (& use for pollination & seed production). The clone that is resident with the U. quelchii hasn't flowered in 2 years.
Knowing you though, both will just take off and flower for years .
Here's a few quick pics of the U. campbelliana flower stalks. I had to raise the treefern slab because the stalks come out at the bottom of the treefern & then droop. That's fine if they were in a tree somewhere - but not at the bottom of a small tank.

Let's hope it keeps progressing
Hopefully the camp will open soon, the more I see the growth habit of it the more I think I want one.
