41. While you reade in _Theophrastus_, or modern Herbalists, a strict division of Plants, into _Arbor_, _Frutex_, _Suffrutex et Herba_, you cannot but take notice of the Scriptural division at the Creation, into _Tree_ and _Herb_: and this may seem too narrow to comprehend the Classis of Vegetables; which, notwithstanding, may be sufficient, and a plain and intelligible division thereof. And therefore in this difficulty concerning the division of Plants, the learned Botanist, _Cæsalpinus_, thus concludeth. _Clarius agemus si alterâ divisione neglectâ, duo tantùm Plantarum genera substituamus, Arborem scilicet, et Herbam, conjungentes cum Arboribus Frutices, et cum Herba Suffrutices_; _Frutices_ being the lesser Trees, and _Suffrutices_ the larger, harder and more solid Herbs. And this division into Herb and Tree, may also suffice, if we take in that natural ground of the division of perfect Plants, and such as grow from Seeds. For Plants, in their first production, do send forth two Leaves adjoining to the Seed; and then afterwards, do either produce two other Leaves, and so successively before any Stalk; and such go under the name of Πόα, Βοτάνη, or _Herb_; or else, after the first Leaves succeeding to the Seed Leaves, they send forth a Stalk, or rudiment of a Stalk before any other Leaves, and such fall under the Classis of Δένδρον, or _Tree_. So that, in this natural division, there are but two grand differences, that is, _Tree_ and _Herb_. The _Frutex_ and _Suffrutex_ have the way of production from the Seed, and in other respects the _Suffrutices_, or _Cremia_, have a middle and participating nature, and referable unto Herbs. [Sidenote: _The Bay Tree, in_ Psal. 37. 35]
