PREFACE. 



In compiling this catalogue our aim has been to give, as com- 

 pletely as possible, a list of all the Phoenogamous and Vascular Cryp- 

 togamous plants known to grow, or to have grown, in Richmond 

 Co. Many friends have kindly helped us to fill gaps in our list, and 

 to make it as complete as possible up to the present time ; but as we 

 shall no doubt have new species come to our notice in the Future, it 

 may become necessary to issue an appendix, and, to render this still 

 more exhaustive, we shall be very grateful for any communication 

 relative to species not mentioned by us. 



Wherever the abbreviation T. C. B. occurs it is meant to represent 

 Torrey Club Bulletin, the organ of the Torrey Botanical Club. 



All species not found personally, we have credited with the name 

 of the persons by whom they were reported to us. The Elliot Col- 

 lection, referred to often, is a collection made for the late Dr. S. Elliot, 

 of New Brighton, which is very valuable for containing many species 

 whose localities are now destroyed, and the plants themselves extinct.
