1920] Long,—Gentiana Andrewsii in New Jersey 109 
ity. The prompt discovery of G. clausa as a frequent and charac- 
teristic plant of the low, swampy woods along Shark River above the 
village of Hamilton (formerly. Shark River) left little to be desired 
in the matter of a solution for “G. Andrewsii.” When to this fre- 
quence of G. clausa was added only a single station for G. Saponaria 
(and that well across the country toward Farmingdale) discovered 
during the day's tramp, one could readily believe in the acuteness of 
Knieskern's observation. 
In middle New Jersey the Coastal Plain covers a considerable 
portion of Mercer and Middlesex Counties and touches several other 
counties near New York City, but there are no published locality 
records for the species from this area. Correspondence and the 
examination of collections has brought to light little information 
on stations, additional to Trenton, occurring about this portion of 
the Coastal Plain. Dr. F. W. Pennell writes me of a specimen at 
the New York Botanical Garden labeled as collected in Bergen 
County at Moonachie—which is on the edge of the Hackensack 
Marshes. Mr. Mackenzie tells me that he has collected the species 
a short distance south of Hackensack (a region very close to Moon- 
achie) and notes that the flora here is predominantly Piedmont. 
The Coastal Plain is often such a narrow strip in this region that one 
would hesitate to believe that the plant along the Hackensack Marshes 
belongs to this association rather than to the general Piedmont 
flora. 
Though this evidence, it must be confessed, is not wholly conclu- 
sive that G. Andrewsii is one of the rarest of plants in the Coastal 
Plain of New Jersey, it is certainly significant that the only satis- 
factory demonstration of its occurrence in this area rests upon ma- 
terial from the alluvial marshes of the Delaware River. The species 
is a frequent and characteristic plant of the adjacent Piedmont Pla- 
teau of Pennsylvania, and in the Piedmont region of New Jersey, 
the impression of Mr. Mackenzie, who is probably more familiar 
with that area than any other botanist, is that, while not abundant 
the plant is widely distributed and occurs in many places. It thus 
seems logical to believe that the Camden and Trenton stations re-
