Yes, it's a pity, though, to illustrate such a really badly pressed specimen with pinnae all overlapping and folded over- it is an example of how NOT to prepare herbarium-specimens. Doesn't anyone there teach how to prepate good specimens? You don't just shove leaves in paper without spreading them out properly. Otherwise they become so hard to identify and to learn from.
