Hi, funkychips..
Great looking paphs you have..
Your 1st NoID paph is probably one of the dark (vinicolour) Maudiae type paph hybrids from Taiwan.. Usually, they cost around RM50 each and in not so good condition.. If you got yours for less, its a steal..
I cannot accurately identify the second one for you, but it looks like niveum. I'm not sure if your delenatii is what the seller claims it is.. Your plant looks different from mine. Yes, your 'niveum' is probably concolor...
Don't mind me saying this, but some of your paphs (especially the single growth ones) look grossly overpotted. Paphs like to have the smallest size pot that will contain their roots and they often can be potted back into the old pot when you change medium. This is particularly important for those from section barbata, which have relatively thin roots and are prone to root rot, and brachys, which like to have their roots squeezed into a small pot and need excellent drainage and aeration. Members of these 2 sections also tend to have few roots, in comparison to more vigorous multifloral hybrids like Jogjae and Shireen.
However, all also depends on your growing conditions. If your growing environment is very dry, then large pots and the inclusion of sphagnum in the mix should suit the plants better. But if your growing area is relatively moist, I suggest repotting all your paphs in smaller pots and use better draining medium like fern root instead of sphagnum. Paph roots tend to rot when kept excessively wet, especially if you grow your plants exposed to the rain...
