FLORA CESTRICA WHEN this revised Edition was commenced, it was contemplated with the aid of kind Friends to insert a brief description of all the indigenous species of the Vegetable Kingdom which had been detected in our County, together with such introduced plants as had become naturalized, or were CULTIVATED for useful purposes.

It soon became apparent, however, that the lower Orders (especially the Fungi) were so multitudinous, as well as obscure, that it would require more time to accomplish the undertaking, than , at least, had any right to reckon upon.

It was found, also, that to include the whole, would render the work inconveniently voluminous.

A descriptive enumeration of the Fungi, alone, would make a respect- able volume.

It was therefore concluded to omit all below the Lichens, and leave that portion of our Botany to the future enter- prise of our Chester County Naturalists.
