Meaning
The phrase arbor philosophorum names the tree-shaped metallic result claimed in Book 2; herbam auream, golden plant, is an accompanying name. The text first says gold grows “in the manner of a tree,” then describes branches, leaves and a delightful shrub. The comparison concerns visible form, and the naming does not itself assert the production of an ordinary living botanical organism. Philosophorum identifies a learned alchemical association, not ownership by a separately identified group of philosophers in the dedication.
Use in the book
The example follows a claim that gold can increase in weight and body. It offers a spectacular, visible image of growth: gold in a vessel is said to rise with many little branches and leaves. The practitioner’s diligence and skill are foregrounded, and the sight is described as delightful and astonishing. This rhetoric of wonder makes the form itself an attraction in addition to any possible usefulness.
The process language names calcination and several historical waters, followed by repeated distillation. The claim is then extended to Silver and other metals, but with explicit differences in calcination and the water used. Those differences are left to the reader’s experience. The passage therefore does not offer one unqualified method for every metal.
The succeeding flint example similarly emphasizes a visible shape, now that of the vessel rather than a tree, and frankly admits a lack of benefit. Read together, these examples show growth as a source of wonder and evidence claimed for art’s power over form. They should not be confused with the separate philosophers’ stone mentioned in the three-principle account merely because both names contain philosophorum.

Translation in this edition
The edition’s note says the name need not imply a living plant. It retains aqua regis, aqua fortis and aqua gradationis as historical reagent names, and leaves the reader’s experience clause intact rather than silently filling in unspecified adaptations.
