THE CAYUGA FLORA. xxix 



not. All localities without name of person, are supposed to be from 

 the personal observation of the writer. Wherever an exclamation 

 point follows a name it signifies that the writer has verified the dis- 

 covery, by himself observing the same station. Those plants so com- 

 mon as to need no special mention, are considered the common pro- 

 perty of all observers, and therefore no discoverer's name is added. 



4. Each species, variety, or especially marked form found with our 

 Cayuga L. basin has its catalogue number, provided the plant is na- 

 tive, or has become established. 



5. Those without numbers and without enclosing brackets are not 

 regarded as yet permanently established within our limits. 



6. Those without numbers but enclosed in brackets are found in 

 the basins of Keuka or Seneca Lakes but not in that of Cayuga. 



7. Species with names in heav}^-faced type, are supposed to be indi- 

 genous. 



8. Species with names in small capitals are not regarded as indige- 

 nous. 



9. Whenever a species is not described in Gray's Manual 5th edi- 

 tion, a description is given in this catalogue if the form is regarded 

 as permanent or important, and all references to Gray's Manual are 

 to the 5th Edition. 



10. The classification of Orders and Genera adopted, is that of Ben- 

 tham and Hooker's Genera Plantarum; except that the arrangement 

 in Gray's Synoptical Flora is preferred wherever that varies from the 

 former. In the present unsettled condition of the Carices it was 

 thought best to adhere to the old established arrangement of species 

 as given by Care}' in Gray's Man. The writer has also been conserva- 

 tive about adopting all the numerous changes made in the nomencla- 

 ture of that genus. 



11. The letters H., C, or H. and C, refer to the work of Dr. H. 

 P. Sartwell, of Penn Yan, on the plants of the valleys of Seneca and 

 Keuka Lakes. He was an accurate observer, an indefatigable worker, 

 and in Senate Doc. No. 51, a report of the Regents of the University 

 of the State of N. Y. for 1844, he published a catalogue of plants found 

 in these two basins, and afterward disposed of his entire collection 

 including specimens of most of those given in his catalogue, to Ham- 

 ilton College. This collection 'is the " Herb. SartweW or the " H" 

 of the following pages. "Cat. of T844" or " C," refers to the above- 

 named catalogue excluding those plants known to have been found 

 only outside of the two lake basins. This catalogue contained 947 

 species, — not all of them found in the Seneca and Keuka regions — and 

 to this Dr. S. H. Wright has for my convenience added all the recent 

 discoveries known to him, 85 in number. His additions are indicated 

 by the expression "Dr. Wright in C." Our cordial acknowledge- 

 ments are due Dr. Wright for this and other kind acts. The follow- 

 ing catalogue, therefore, furnishes not only the student of our flora a 

 basis for future work, but the student of the Keuka and Seneca flora 

 with similar, though less complete knowledge.
