THE FERN BULLETIN 



discovered considerable Woodwardia virginica grow- 

 ing in the shrub zone with Rosa Carolina, Alnus in- 

 cana, Rhus vernix, and some Sphagnum. The collec- 

 tion was made August 5, 1909, the spores then just be- 

 ginning to be shed. This Woodzvardia station is about 

 eight miles southwest of Professor Hill's station. 



There is also in the herbarium of the Carnegie Mus- 

 eum a sheet of Woodwardia virginica from the her- 

 barium of Lafayette College as collected by the late 

 Professor T. C. Porter and bearing the following in- 

 scription : "Sphagnum bog. Center Co., Pa., 4 miles 

 n. w. of Pennsylvania Furnace, el. 1200 ft. Aug. 

 1875." This station for the fern is somewhat west of 

 the center of the State and unlike our other station is 

 not in glacial territory, but is about one hundred miles 

 south of the terminal moraine, and is in one of the bogs 

 in the interesting pine barrens of Center County on 

 residual soil, derived from limestone with subterran- 

 ean drainage. 



The small lake mentioned on page 67 by Professor 

 Hill as situated near the vilage of Edinboro. Erie 

 County, is Conneautte Lake. Conneaut Lake is in 

 Crawford County, about twenty miles to the south and 

 west. — This is to avoid possible confusion of localities. 



In the herbarium of the Carnegie Museum there are 

 now specimens of the Boulder Fern (Dcnnstedtia or 

 Dicksonia) from twelve of the thirty-one counties in 

 the western half of Pennsylvania. One of the speci- 

 mens is from Crawford County : "Conneaut Lake, east 

 side, woods back of Harmonsburg road. John A. 

 Shafer, July 24, 1901."; another is from Lawrence 

 County : "Old R. R. track above Wurtemberg, on rock- 

 cut. John A. Shafer, July 15, 1900." The other speci- 

 mens are all from unglaciated and more or less hilly or 

 mountainous counties, and the card-map on which our
