Alpina also has a larger, coarser appearance in the field. To- 

 day nine-tenths of the collectors will get glabella and never find 

 alpina; this is partially owing to the scarcity and more inac- 

 cessible localities in which the latter grows, but more largely to 

 the fact that the eye has to be trained to distinguish them in the 

 field, although after once seeing them one can recognize them at a 

 longdistance. We are more of ten deceived now by smooth forms 

 of Ilvensis than by glabella, in fact some smooth forms of Ilvensis 

 require an expert to separate from alpina. In eleven trips to 

 Smuggler's Notch we have seen the latter but three times; it was 

 a red letter day for Dr. A. J. Grout and myself on Aug. 25th, 

 1893, when we found both this species and Dryopteris fragrans, 

 after searching for them several times. 



Again in 1897 we saw it, but the most successful trip for it 

 was this season with Prof. Balch. First we found it on Mansfield 

 Nose at about 4,000; then very fine specimens in the high cliffs of 

 Pringle's Ravine, Smuggler's Notch. Much of our success in 

 ferns and other " Notch" plants has been due to the counsel of 

 C. G. Pringle, who, by the way, was in Smuggler's Notch this 

 July for the first time in sixteen years.

ISOETES DODGEI— A NEW STATION 



By T. Chalkley Palmer. 



HE writer has to thank Mr. Joseph Crawford, of Philadelphia, 



for an opportunity to- study certain Isoetes material to 



which that gentleman's attention had been called by Dr. G. 

 N. Best, of Rosemont, N. J., during a botanical expedition on 

 July 4th of the present year. The plants were collected at Point 

 Pleasant, Pa., on the Delaware. A hasty examination might lead 

 one to call them /. riparia, but a careful study shows them to be 

 /. Dodge i A. A. Eaton. To find this species cropping up so far 

 away from its original and hitherto almost unique station seemed 

 of great interest. After some correspondence, Dr. Best was kind 

 enough to forward more of the plants in a living condition, and a 

 comparison of aspect and habit of growth could then be made 

 between them and the living material with which the writer was 

 favored by Mr. Eaton in 1897 and 1898. 



The East Kingston plants and these are identical in diagnostic 

 characters, but differ somewhat in aspect. Those from Point 

 Pleasant have smaller trunks and straighter leaves. They are
