the localities in which they have found it. These state- 

 ments should include a resume of the facts regarding 

 the soil, dampness, associated plants, and exposure, or 

 any others of importance. It will not be necessary to 

 put the facts in form for publication, as it may be neces- 

 sary if a large number respond, to summarize the re- 

 plies anyway. One point will be of particular interest 

 in connection with a fact noted by Prof. Campbell 

 in his monograph on the Ophioglossaceae. He re- 

 cords the finding of at least most of the prothallia 

 studied in locations where it was evident that the ground 

 was subject to flooding at some period of the year. In 

 this connection Mr. Webb's description of the habitat of 

 0, Engelmanii in Missouri is interesting. Below I pre- 

 sent a record of the localities in which I have found 

 Ophioglossum . 



1. Orange, New Jersey. Low flat sedgy meadow, 

 dry at that time, early July, but probably wet after any 

 hard rain; no shade. Sphagnum occured in small 

 patches for some time in the field. 



2. Cornwall, Connecticut. Low, wot, boggy meadow; 

 no shade; Sphagnum present; soil mucky. 



3. Toms River, New Jersey. Low swamp; sandy 

 soil; Sphagnum present in patches; the Ophioglossum 

 occurred at the edge of a thicket, partly shaded. 



4. Springside, Hackensack River Valley, N. J. Wet, 

 sedgy, swamp meadow, probably dry later in the summer. 

 Similar to the Cornwall station described above although 

 no Sphagnum appeared to be present. This station 

 was discovered this spring by Dr. A. B. Stout, of the 

 New York Botanical Garden. It contains many thous- 

 ands of plants. Probably all along the Hackensack 



meadows similar stations occur. 



The four situations are essentially the same in that 

 all represent more or less boggy conditions favored by 

 Sphagnum. Where have you found the adder's tongue? 



Brooklyn, N. Y.
