PELLAEA ATROPERPUREA AN EVERGREEN. 



By E. J. Hill. 



In Rhodora for March, 1902. p. 54. Mr. Davenport notes that 

 this is doubtfully an evergreen in New England. It is plainly 

 one in Illinois. I observed them April 10th, this year, at various 

 places on the ledges of limestone at Lemont and Lockport, and 

 found that the greater part of the stems had survived the winter 

 and were still fresh. The pinnae on some tufts in the most ex- 

 posed positions, as well as in individual stems among those still 

 green, were brown and withered. They were generally adherent, 

 but some stems were naked. Herbarium specimens collected in 

 these localities May 24th, 1899, and June 29th, 1898,. have old 

 stems mixed with the new, some of the sori still remaining under 

 the recurved edges of the pinnae. New fronds had in the most 

 vigorous examples reached the height of nearly a foot at the 

 latter date, the fruit dots well on their way. It is possible to 

 obtain the ripened fruit of a preceding year at the time one gets 

 some rather immature of the current year. P. airopurpurea is 

 as much an evergreen in this vicinity as the Christmas fern 

 (Polystichum acrostichoides) .

NOTES FROM THE SOUTH-IIL 



By Willard N. Clute. 



Selecinella Ludoviciana.— So little is known about this 

 species that a question has always existed as to its distinctness 

 from 5*. apus. In the vicinity of New Orleans it is not an un- 

 common plant, and the several opportunities that I have had for 

 studying it convinces me that it is fully entitled to specific rank. 

 It was. originally discovered at Covington, La., by Drummond, 

 and I have seen it growing at Pearl River, some miles from Cov- 

 ington, as well as at Ponchatoulas, thirty miles or more north of 

 New Orleans. It usually occurs in shady spots in the sand bar- 

 rens and may be distinguished from S. apus at a glance by the 

 principal stems which are stiffly erect. It begins to renew its 

 growth about the end of March and for a time the new branch- 

 lets are slightly drooping. Prof. R. S. Cocks has presented me
