ATHYRIUM FILIX-FEMINA (L.) Roth 
General throughout, on all soils and formations. Most abun- 
dant in the bogs and along streams on the South Mountains. 
Fronds 9 dm. (3.6+5.4) long and 2.8 dm. wide represent average 
luxuriance in one form of the species. It has been collected with 
mature fruit on July 2. Herbaceous. The variability of this 
species is well known. 
BoTRYCHIUM DISSECTUM Spreng. 
Not infrequent throughout, but most general and abundant 
on the South Mountains: Plants with fronds 10.5 cm. long and 
18 cm. wide and standing 4.5 dm. high to top of fertile frond 
represent maximum luxuriance. One plant in fruit with blade 
1.5 cm. long and 2.5 cm. wide standing 9.5 cm. high has been 
collected. Collected in fruit on August 25. Fertile fronds have 
been found still erect in November but are generally prostrate 
and: withering at’ that time. Sterile fronds turning bronze red 
and lasting through the winter. 
BorryCHIUM LANCEOLATUM (S. G. Gmel.) Angs. 
Vicinity of bog 1 mile south by southwest of Mountainville, 
September 25, 1909, 2248. Back of Gruver’s, along the third 
streamlet, 134 miles east by northeast of Mountainville, September 
25, 1910, 2984. Above Idlewild, along streamlet at Mountain- 
ville, October 8, 1910, 3008. 
Collected only at these stations on the South Mountains. 
Only eight plants have been seen, the largest standing 16 cm. 
high. Attention is directed to the dates when the spores were in 
good condition as well as the comparative rarity of the plants. 
B. neglectum on these dates had entirely disappeared from the 
stations where it was earlier abundant. 
All stations for this species are from counties in the mountains 
to the north and northwest, excepting the above and a record 
published in Torreya* by W. H. Leibelsperger for Fleetwood, 
Berks County.
