Most certain plant ID's?

That logic might work if you look at only one drawing ( You are not allowed to view links. Register or Login to view. ).

But if you look at all the drawings, you find that the illustrator draws other plants with overlapping leaves mostly like You are not allowed to view links. Register or Login to view. and those with pinnatisect leaves in a completely different way, as in You are not allowed to view links. Register or Login to view. , which suggests that You are not allowed to view links. Register or Login to view. probably does not have pinnatisect leaves.
