Another caution, no less useful, we have from that excellent and judicious Botanist Mr. _Humphrey Bowen_, to beware of a poisonous species of _Vulvaria_, too often mistaken for the wholesome one, and which, if suffer'd too near our trees, will very greatly endanger their well-being. He tells us, in the 12th volume of his large abridgment of _la Quintinye_, that before he had acquir'd his judgment and experience, some of his plants have often been sufferers through this mistake; and he has seen a tall thriving tree, by the contact: only of this venomous shrub, become _porrose, scabiose_, and cover'd with _fungous Excrescences_ not unlike the fruits of the _Ficus sylvestris_ in which case the _succus_ also has lost both its colour and vertue; and the tree itself has so much partaken of the nature of the venomous shrub that had hurt it, that itself has become venomous, and spread the poison through a whole Plantation. These distempers of a tree of the greatest use and value, have employ'd the labours of the most eminent Botanists and Gardeners, to seek out remedies for them: In which, however, none have succeeded like the celebrated _Dr. Misaubin_ who from his profound knowledge in Botany has composed a most elaborate work upon _all the things that can happen_, both to the _Arbor Vitae_ and _Vulvaria also_: There he has taught a certain cure for all these evils; and, what is most wonderful, has even found out a way of making the most venomous _Vulvaria_ itself wholesome, which he practises daily, to the satisfaction of all that apply to him. These venomous _Vulvaria_ are but too common in most gardens about _London_; there are many in St. _James's Park_, and more in the celebrated gardens at _Vaux-hall_ over the water. _The_ NAMES _and_ VIRTUES. Besides the common name of _Arbor Vitae_, a very learned Philosopher and great Divine would have it call'd, _Arbor Scientiae boni & mali_; believing, upon very good grounds, this is the tree which grew in the middle of the garden of _Eden_, and whose fruits were so alluring to our first mother. Others would have it call'd the _Mandrake_ of _Leah_, persuaded it is the same whose juice made the before barren _Rachel_ a joyful mother of children. The learned _Madame D'Acier_ in her notes upon _Homer_ contends it should be called _Nepenthes_. She gives many reasons why it certainly is that very plant, whose fruits the _Egyptian_ queen recommended to _Helen_, as a certain cure for pain and grief of all sorts, and which She ever after kept by her as her most precious jewel, and made use of as a _Panacaea_ upon all occasions.
