This includes striolata and, by affiliation, auriculata. However, these crypts (or, at least, many strains) are very different from the usual limestone/karst crypts and *much* more difficult to grow/propagate than the other listed crypts. I'd strongly recommend to keep them in a separate category to avoid them being killed by enthusiastic buyers. There's a lot of habitat information and pics of collecting localities published or even available on the net and I'd hope that folks tap that these sources before resorting to trial and error testing with crypts collected from nature...You can add bullosa and keei to the list too.
Yes, if any submersed crypt doesn't grow as nicely as expected, increasing the current can help to overcome some problems.I've found that the hard water Crypts really benefit from fast flowing water too.
Can do.Please add pontiderifolia. It grows on limestone and does spectacularly well in the liquid rock here that passes for tapwater.
