the parvis are prone to forming stolons much like phrag besseae...basically runners that grow right below the surface and then magically re-appear up to 6 inches away, or out through a drainage hole, or wherever it damn well pleases.
you see this in armeniacum all the time, frequently in micranthum, more rarely in malipoense. I don't think delenatii does this, and I don't have any experience with the other parvis.
I don't know why a plant will grow normally at times and at other times produce a million stolons.
theoretically it is possible for the entire plant to die of an infection if a stolon gets trapped somewhere and rots...although in the vast majority of cases the stolon dies and that's it, no problem to the main plant.
I have seen a delenatii that produce new growth with a short rhizome but it is very uncommon. It was a seedling that I gave a friend and she flowered it this year. The other delenatii did not do that.
Paph micanthum likes warm humid days with bright light and cool nights with low humidity. They can survive down to 50 F at night with no problems. They don't do well with warm night temperature at 70 F for some reason. Evening air circulation is important for this plant because it can rot the plants due to moisture at the leaf axil. Under these conditions Paph armeniacum and Paph miranthum grow very well and will put out a lot of new growths.
