to find their way into herbaria where they may constitute a per- 

 manent record. The desirability of filling in such gaps before 

 the encroachment of the cities destroys the opportunity for work of 

 this character is apparent to all. 



Members of the club or others interested are invited to send to 

 the writer any stations for the plants to be discussed presently, 

 that will throw light on the problems stated, and full acknowl- 

 edgment for material thus submitted will be made. In order 

 that the record of any station may be permanent it is essential 

 that a specimen be placed in the club herbarium. Specimens 

 thus deposited will always serve as a basis for a list of plant sta- 

 tions. They will also put at rest any doubts of subsequent 

 workers who are at liberty to take on trust or not a printed list 

 of plant stations, but are obliged to reckon with specimens ac- 

 tually collected from them. It also minimizes the often unavoid- 

 able errors in the determination of difficult or critical species. 

 Only plants collected within the local flora range * are desired, 

 and any notes made on distribution are understood to apply ex- 

 clusively to this area. 



The list follows : 



PiNACEAE 



. I. Pinus resinosa Ait. No specimens from the range. In 

 Bull, Torrey Club 3 : 45, a station at Inwood, New York City, 

 is recorded. Beyond this no stations are recorded so far as 

 known, except Luzerne and Wayne counties. Pa. In the 

 state herbarium at Albany there are specimens from Greene and 

 Columbia counties. It has been impossible to verify the Inwood 

 record, and the question arises Does it occur between this and 

 the upper Hudson region ? Also, if it is in Luzerne and Wayne 

 counties in Pennsylvania, why not in Lackawanna and also in 

 Delaware county, N. Y.? According to recent treatments it occurs 

 throughout New York and the upper part of Pennsylvania. 



* The local flora range as prescribed by the club's preliminary catalog of 1888 is 

 as follows : All the state of Connecticut ; Long Island ; in New York, the counties 

 bordering the Hudson valley, up to and including Columbia and Greene, also Sulli- 

 van and Delaware counties ; all the state of New Jersey ; and Pike, Wayne, Monroe, 

 Lackawanna, Luzerne, Northampton, Lehigh, Carbon, Bucks, Berks, Schuylkill, 

 Montgomery, Philadelphia, Delaware, and Chester counties in Pennsylvania.
