The Trees with a Corolla are again distributed into such as have one or many petals, and those regular or irregular.—Herbs with a Corolla have that part either compound (as the Dandelion, Thistle and Daisy), or simple; the latter being either of one or many petals, and in either case regular or irregular. We come at last to the final sections, or classes, of the Tournefortian system. Herbs with a simple, monopetalous, regular corolla are either bell-shaped or funnel-shaped; those with an irregular one either anomalous or labiate.
Herbs with a simple, polypetalous, regular corolla are either cruciform, rosaceous, umbellate, pink-like or liliaceous; those with an irregular one, papilionaceous or anomalous. The subdivisions of the classes are founded on the fruit.
It is easy to perceive that a system of this kind can never provide for all the forms of corolla which may be discovered after its first contrivance; and therefore the celebrated Dr. Garden, who studied by it, assured me that when he attempted to reduce the Ame-
