nopetalous, regular corolla are either bell-shaped or fun= 

 nel-shaped ; those with an irregular one either anoma- 

 lous or labiate. 



Herbs with a simple, polypetalous regular corolla are 

 either cruciform, rosaceous, umbellate, pink-like or lilia- 

 ceous ; those with an irregular one, papilionaceous or 

 anomalous. The subdivisions of the classes are found- 

 ed 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 American plants 

 to Tournefort's classes, he found them so untractable, 

 that, after attempting in vain to correct or augment the 

 system, he should probably have given up the science 

 in despair, had not the works of Linnaeus fallen in his 

 way. 



Magnol, Professor at Montpellier, and even Linnaeus 

 himself, formed schemes of arranging plants by the ca- 

 lyx, which nobody has followed. 



All preceding systems, and all controversies respect- 

 ing their superior merits, were laid aside, as soon as the 

 famous Linucean method of classification, founded on 

 the Stamens and Pistils, became known in the botanical 

 world. Linnaeus, after proving these organs to be the 

 most essential of all to the very being of a plant,first con- 

 ceived the fortunate idea of rendering them subservient 

 to the purposes of methodical arrangement, taking into 

 coHoideration their number, situation and proportion.
