as shown by the books, are Philadelphia and Lehigh counties in 

 Pennsylvania. Has the tree established itself on Long Island? 



8. Quercus Alexanderi Britton. Until recently this tree was 

 not supposed to grow in our range, but specimens from Pough- 

 keepsie and West Point indicate an apparent migration down the 

 Hudson Valley. Has any one taken specimens from elsewhere 

 in the range? 



9. Quercus hicolor Willd. {Q. platanoides of the manual). Our 

 specimens and the published records all show this as a rare tree 

 in the pine-barren region. How generally distributed in this 

 region is this species? 



10. Quercus lyrata Walt. Riddleton, Salem Co., N. J., is the 

 only station represented by specimens. According to the New 

 Jersey catalog it is "Common in the middle and southern coun- 

 ties." Any specimens from this region will be welcome. 



Ulmaceae 



1. Ulmus Thomasii Sargent. {U. racemosa of the manual). In 

 the catalog of the New Jersey plants there is the following record : 

 "Along L. & H. R. R. R. above Woodruff's Gap, a single tree 

 observed — Porter and Britton, 1887." There is a specimen for 

 this record and one doubtful collection from Weehawken, N. J., 

 many years ago. Beyond this nothing seems to be known of its 

 distribution in our range. 



2. Ulmus fulva Michx. This species well illustrates a dis- 

 crepancy in the distribution of a great many of our local plants, 

 as given in general works. "Quebec to Florida," etc., is about 

 the general range given for the tree, while the fact is that it 

 grows in our region only north and west of the coastal plain 

 region. There are at least 500 species in our area that follow 

 this line of distribution, and are to be excluded from the coastal- 

 plain region altogether. 



3. Celtis georgiana Small. In the Flora of Southeastern United 

 States (page 365) this species is described as growing from Mary- 

 land to Georgia, etc. Since its discovery it has turned up in a 

 number of new stations, among them one from Newton, Sussex 

 Co., N. J. The specimens are perfectly authentic and apparently
