Such a delicately done, lovely ink drawing, detailing 39 different types/shapes of leaves, each one labeled with scientific name. Of course I especially love the star shaped ones that look like hex drawings! A perfect gift for a nature lover or arborist if I ever saw one. 1st half of the 19th c, I'd guess earlier than later, surely from a school notebook on botany. Black ink on watermarked laid paper. 

10" x 8". Very good condition, with a couple of very  light stains, minor.  Clearly was removed at some point from a school notebook.
