I30 REPORT OF NEW JERSEY STATE MUSEUM. 



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

 to midsummer.

PTERIDIUM Scopoli. 



Pteridium aquilinum (L.). BracJcen. 



Pteris aquilina Linnaeus, Sp. PI. 1075. 1753 [Europe]. — Barton II. 211. — 

 Knieskern 40. — Willis 78. — Britton 306. 



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 pseudocaudatum Clute (Fern Bull. VIII., 39, 

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

 of combinations and gradations to true aquilinum. 



Spores Mature. — July to September, showing great variation 

 in date. 



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

 viding Creek.

 erton. Speedwell, Winslow, Taunton, Hammonton (Bassett), Egg Harbor,
