NOTES FROM LOUISIANA. 



By R. S. Cocks. 



Azoixa Caroliniana Willd. — During the past summer there 

 has been a most extraordinary growth of Azolla in a small pond 

 in Audubon Park, New Orleans. Between the months of June 

 and September no less than fourteen cart loads, weighing per- 

 haps seven tons, were removed from a sheet of water not more 

 than one-fourth of an acre in area. On an average the growth 

 had to be removed every twelve days. The writer would very 

 much like to know whether such extraordinary luxuriance has 

 been elsewhere reported. 



Adiantum pedatum L. — In the " Fern-flora of Louisiana " by 

 Mr. Clute and the writer this fern was only tentatively included, 

 as no undoubted specimens from the State had been seen. Since 

 then specimens have been procured from near Baton Rouge 

 through the kindness of Dr. Billings, the State Botanist, and 

 also from another station, so that this fern can now be safely 

 added to our list. 



Adiantum Capillus-veneris L. — In the writer's opinion, 

 his friend Mr. Clute to the contrary notwithstanding, this 

 fern should be stricken out of our flora. In its natural state 

 it invariably is found on limestone banks with water trickling 

 over it, and in the whole of Louisiana, so far as the writer 

 knows, no such situation exists. In his opinion it is not found 

 in a natural condition in the cemetery from which Mr. Clute 

 reported it, nor would it remain there very long unless occasion- 

 ally assisted by gardeners and other friends. Dr. Small in his 

 flora states that A. capillus-veneris is "rare or local; south to 

 Florida and Louisiana." " Rare and local " are not very happy
