Green Lion in alchemy

This stuff was sitting right in front of your eyes for centuries, pretty embarrassing for the academy. I was first alerted to this aspect of alchemy by a text known as the Aphorisms of Urbigerus, originally printed in London in 1690. The passage that caught my eye reads:

Our true and real Matter is only a vapor . . . This Green Dragon is the natural Gold of the Philosophers, exceedingly different from the vulgar, which is corporeal and dead . . . Our Gold is called Natural, because it is not to be made by Art, and since it is known to none, but the true Disciples of Hermes, who understand how to separate it from its original Lump, ‘tis also called Philosophical; and if God had not been so gracious, as to create this first Chaos to our hand, all our Skill and Art in the Construction of the great Elixir would be in vain.[1]
This suggested cannabis, being a vapor, green, and requiring the separation of its “original Lump,” so I pored over the alchemy corpus looking for references to Green Dragon or Green Lion.
