found growing in Livingston Park. The largest grows at No. 5 Liv- 

 ingston Park. The girth is 8.3 feet, and the height is 80 feet. 



Ashniua triloba Adans., the Papaw, is a rare native shrub or 

 small tree. The only known station in the vicinity of Rochester 

 where it grows wild is on the Budlong farm in the town of Greece 

 north of the Ridge Road. There is a thick colony of arborescent 

 shrubs, which annually bear ({uantities of fruit. There is a similar 

 native colony of the Papaw growing near Brockport. 



A great deal of work has been done by members of the Park 

 Department, and the Botanical Section of the Academy of Science 

 ■during the past seventeen years in studying and investigating the 

 genus Crataegus (American Hawthorn) in the vicinity of Rochester. 

 Western New York and elsewhere, in collaboration with Dr. C. S. 

 Sargent, the Director of the Arnold Arboretum, Harvard University. 

 Many new species were discovered. One of the most interesting 

 of the new arborescent species was named after the late George Ell- 

 wanger:' Crataegus EH-u'aiigeriaiw Sargent. The type plant stands 

 at the west end of the grass walk in the Ellwanger & Barry Nurseries 

 • on Mt. Hope Avenue. Mr. Ellwanger said a few years before his 

 death that he remembered this hawthorn very well fifty years .ago, 

 and he did not observe any perceptible increase in its size during 

 that time. If no increase was noticed in this hawthorn in a period 

 extending over sixty years, it surely must be of considerable age. 

 and must have started on its life history long before it was seen by 

 a white man. The circumference is 3.7 feet and the height 25 feet. 



Gymnocladus Canadensis K. Koch., the Kentucky Coft'ee Tree, 

 has been planted to some extent in the city. A well balanced tree 

 grows on the grounds of H. B. Graves with a girth of 4 feet, and a 

 height of 40 feet. At the corner of Bay Street and Culver Road on 

 the grounds of the old McGonegal home there is a Kentucky Coffee 

 Tree with a remarkably wide spreading head. The girth is 4.6 feet, 

 and the height 38 feet. A large Kentucky Coffee Tree grows at No. 

 174 South Goodman Street in front of the house. The circumfer- 

 ence is 5.5 feet, and the height 50 feet. Another large Kentucky 

 Coffee Tree grows on the grounds of the Homeopathic Hospital on 

 Alexander Street, the girth is 5.5 feet, and the height 55.8 feet.
