Have you looked at the ATP database link that Lin referenced? That brings up the entries for H. fasciata and H. subfasciata. There is no distinguishing information included. I can't look at the entries and discern how to differentiate between the two. There are a lot of photos under fasciata. I'm betting some of those photos are not fasciata, though I don't doubt at all that was the label under which they were originally purchased. Then if they were propagated and shared the problem gets increasingly compounded. I haven't posted a photo for that reason. It wouldn't provide any clarification because it looks like several of the photos already posted. But what is there does give a good idea of the 'general' type of Haworthia as opposed to others Haworthia types that are easier to distinguish. That is useful information in itself.
