is called Dryopteris unita, while the 6th edition of Underwood's 

 "Our Native Ferns" makes it a variety of unita. Having com- 

 pared the Florida plant with specimens of true Nephrodium uni- 

 tum from Jamaica, collected by myself in the only exact locality 

 that Jenman names for it, I am convinced that our plant should 

 continue to be regarded as a variety, or at least a form. The 

 texture is less coriaceous and the pinnae slightly broader. This, 

 of course, is not unexpected and appears due to the difference in 

 climate. 



Another Station for Psilotum nudum. — Since I noted a 

 station for Psilotum nudum at Sanford, Florida, Mrs. M. A. 

 Noble has sent me specimens from the vicinity of Lake Helen, 

 Florida. This is not so far distant from Sanford, but the finding 

 of more of it suggests the possibility of its being not uncommon 

 in the general region. Further explorations will doubtless dis- 

 cover it in greater abundance. 



NOTES FROM THE CATSKILLS. 



By J. C. Buchheister. 



Recently I found the largest Botrychium matricariae folium 

 that I know of. It is larger than many specimens of B. Virginia- 

 num or B. ternatum, and decidedly ternate. Sometimes I am in- 

 clined to think that there are two distinct forms of this fern, the 

 simple pinnate one, and the compound, often ternate one. It is 

 the fleshiest of all the Botrychiums, and the simple form is more 

 fleshy than the compound one. 



Botrychium matricariae folium is much inclined to "freaks" 

 and is otherwise variable. Some specimens have two sterile 

 divisions, others two fertile. In some the sterile portion bears 

 sporangia, in others a pinna of the sterile part is transformed in- 

 to a fertile spike, and forming a secondary fertile frond, arising 

 from the blade. Some plants have a ridiculously small sterile 

 division, while the fertile one is gigantic in proportion and much 

 branched. Another remarkable thing is the different way in 

 which the sterile frond is placed. Sometimes it is immediately 

 below the sporangia bearing panicle, sometimes near to the root,
