24 E. Hitchcock, Jr., on a new species of Clathropteris, ; 
tion across the valley at Turner’s Falls, 30 miles north of East_ 
Hampton. a. 
Fig. 2 exhibits portions of several fronds or perhaps only pin-" 
nules of the East Hampton fern. Some of these pinnules—al-— 
though much broken at their extremities—are nearly a foot long, — 
and 4 inches wide, so that probably they were originally at least” 
one foot and a half in length.

The pinnule on the left hand side of the figure, shows the del- 
icate secondary veins, which are usually obscure and therefore — 
this fern has not heretofore been recognised. 1 have presented to 
the Cabinet of Amherst College, a large specimen from E. Hamp- — 
ton containing numerous isolated fronds, and in one place showing — 
a large number most distinctly radiating from a center, like the : 
tree ferns of tropical regions. These radiating fronds are broken — 
off at their extremities, being only 4 to 6 inches in length. The 
specimen which is figured measures nine by thirteen inches, and 
is in the Cabinet of the Williston Seminary at East Hampton.
