I30 REPORT OF NEW JERSEY STATE MUSEUM. 



Common in the northern half of the Stale; rare and local in

 green, persisting with the large sori well into the next year, often 

 to midsummer.

Occurs throughout, but especially abundant in the Pine Barrens, 

 where, with the several species of Huckleberries and the "Sweet 

 Fern," it forms the bulk of the undergrowth in open pine woods. 

 It is indeed the most abundant of the species mentioned, and 

 often large areas are covered by it alone, the flat tops of the 

 fronds making an even surface which stretches away among the 

 scattered trunks of the Pitch Pines as far as the eye can reach. 



The form P. a pseudocandatum Clute (Fern Bull. VIII., 39, 

 1900, Babylon L. I.) occurs at various stations and in all sorts 

 of combinations and gradations to true aquiiinum. 



Spores Mature. — July to September, showing great variation 

 in date. 



Middle District. — Long Branch, New Egypt, Sicklerville, Swedesboro, Di- 

 viding Creek.
