This photo by Phil Garnock-Jones is the true Asplenium bulbiferum. Despite the label on it, the photo below that is probably a hybrid - A. bulbiferum x A. dimorphum - which is commonly grown in gardens in New Zealand and often mistaken for Asplenium bulbiferum. Here is some more info on that. Thanks Phil, for bringing this to my attention.
Are the fiddleheads of the 'fake' just as edible? Any thoughts on this are welcome!
