PLANTS OF MONROE COUNTY. 5 



in the Proceedings of the Rochester Academy of Science, Vol. 4, pp. 

 93-136, June, [903, or the Report of the New York State Botanist for 

 1907 (New York State Museum Bulletin 122), 



The species described since 1907, and those not referred to in the 

 above publications, are properly credited in the list, being numbers 

 1422, 1433, 1434, 1456, 1457, 1480. The majority of the new 

 species are also described in the Silva of North America XIII, or in 

 Trees and Shrubs, by Dr. Sargent. 



The Violas given in the list have been submitted to Ezra Brainerd, 

 of Middlebury, Vt,, and the different species of Rubus have all been 

 examined by William H. Blanchard, of Westminster, Vt. , who has 

 visited Rochester for this purpose. 



The hybrid Ferns have been determined by Dr. Philip Dowell, 

 of Port Richmond, N. Y. , who has made a careful study of these in- 

 termediate forms, and has published the results of his investigations in 

 the Bulletin of the Torrey Botanical Club and in Torreya. Specimens 

 of these Ferns may be found in the herbaria of the Academy of 

 Science, and growing plants can be collected at the stations noted. 



The growth of our city is rapidly crowding out many native 

 plants, but owing to the wisdom and foresight of our Superintendent 

 of Parks, Mr. C. C. Laney, these large enclosures of hundreds of 

 acres have been left, as far as possible, in their natural state, and thus 

 many plants have had their habitat preserved, and are to be found 

 flourishing under the most favorable conditions. This is particularly 

 true of the newly classified genera Viola and Rubus, and many of 

 the type specimens of Crataegus are found within the limits of our 

 city parks.
