Debbie, Schroderae is a hybrid: caudatum x Sedenii.

Getting a root-rotted Paph to grow new roots is definitely a tricky business, and usually won't work if you just repot the plant. You need to put it in an environment where the humidity is extremely high and keep an eye out for leaf rot in the meantime. Sphag n Bag works *sometimes*, but even so, it can take years to get the plant turned around to where it's blooming again--you may as well grow up a little seedling....

On the whole, the hybrids of both types--paphs and phrags--are definitely easier to grow and more tolerant of varying conditions than are the species.
