NOTES. 



The Ames Botanical Laboratory, North Easton, Mass., 

 have duplicates of some of the rare ferns recently col- 

 lected in Southern Florida by Mr. A. A. Eaton. These 

 are offered in exchange for orchids. Those who can 

 supply orchids should write to the Laboratory, stating 

 offers. 



An interesting post-card was recently received from 

 Mr. H. E. Ransier, Manlius, N. Y. The back had been 

 treated with the substance used in making blue-prints, 

 and upon this was printed an excellent likeness of Botry- 

 chium lunaria. This would seem to be an excellent way 

 of treating small ferns, anl might form the basis for a 

 pleasant exchange between members. 



Mr. H. A. Green of Tryon, N. C, notes that the speci- 

 men of Pteris cretica mentioned by Mr. R. M. Harper on 

 page 9 of this volume as having been collected by Mr. 

 Green near Augusta, Georgia, has since been decided to 

 be P. serrulata. Before discovering the mistake, Mr. 

 Green sent the same species out as P. cretica to several 

 correspondents. The error should now be corrected. 



From the " Proceedings of the Natural Science Asso- 

 ciation of Staten Island," of March 18th, 1905, we note 

 that Prof. Philip Dowell has found on Staten Island that 

 form of Nephr odium spinulosum that has been named 

 N. Pittsfordense. It was growing on a stony embank- 

 ment amidst plants of A r . Marginal e and N. Spinulosum 

 — a situation quite like that from which the original 

 plants came. 



While botanizing near Southampton, Long Island, in 

 July, the editor found a new station for Lycopodium 

 alopecuroides. The plants were found on the margin of 

 the small ponds that so often fill the depressions among 

 the sand dunes. The plant has been reported from Long 

 Island several times, but with few exceptions specimens
