76 Agricultural Botany. Vol. VI. 



scientific names employed, are those adopted in the Flora of Chester County — in which 

 work all the plants, here enumerated, may be found described in detail. I have followed 

 the arrano-ement, also, of that Flora — not because it is the best — but because it will be most 

 convenient for those who may choose to refer to it, for the descriptions.
