THE CAYUGA FLORA. xxv 



Statistics of the Catalogue. 



The following tables show at a glance certain general as well as 

 special facts in regard to the composition of our flora as it is set forth 

 in the following catalogue. As the numbers in the catalogue are pre- 

 fixed to both species and- varieties, and also to a few forms unnamed, 

 but which will probably be regarded as varieties when better known, 

 and as some of the more important of recent catalogues use the same 

 system of numbering, the following summaries will be based on that 

 system and will include both forms. In certain important analyses, 

 however, the species and varieties will be distinguished from one 

 another. 



It will be noticed that the catalogue includes several groups of spe- 

 cific and varietal names ; these may be tabulated as follows : 



I. Species native to the Cayuga Flora 963 



II. Species introduce^, in the Cayuga Flora 197 



Total number of species 1160 



III. Varieties — native and introduced 118 



Total of numbered species and varieties 1278 



IV. Species spontaneous but not established 53 



V. Species in Seneca and Keuka Flora not in the Cayuga 42 



No attempt has been made to enumerate the plants we have in ex- 

 cess of those known in the Seneca and Keuka region. That could be 

 done by counting up the species of the catalogue which are followed 

 by " H " or " C," or both ; but the comparison would not be wholly 

 fair until after a S3'stematic exploration of that region, especially in 

 certain districts which have been quite neglected. 



The following tables include only the numbered forms of the cata- 

 logue, — genera, species and varieties, — and have nothing to do with 

 those names without numbers.
