Webera sessilis (Schmid.) Lindb. This moss had not been 
represented in the State Herbarium, but about a year ago it was 
found at Sugar Grove and since then has been found near Christ¬ 
mas Rocks. The capsules of this species, like those of Buxbaumia, 
point toward the source of the light supply. Sullivant gives its 
habitat as “ Clayey or barren soil; not unfrequent in hilly districts ”, 
while Lesquereux and James give it as “Clayey and shady 
sandy banks along roads”. The habitat of that in the Lancaster 
region seems to be somewhat unusual, as in the three places where 
the species was collected—in two ravines at Sugar Grove, and near 
Christmas Rocks—the plants were growing on the vertical faces 
of sandstone, in one instance being associated with Bryoziphium 
norvegicum.

Mnium punctatum (Hedw.). This species has not previously 
been recorded in the State Herbarium, but it seems to be fairly 
common in the Hocking Valley. Sullivant says that it occurs in 
“wet places, on the ground, Alleghany Mountains”, and Les¬ 
quereux and James say “Cold springs and borders of brooks, on 
mountains, rarely fruiting. ” In the Sugar Grove region it is 
usually found near the heads of the ravines where the water runs 
or trickles over the rocks, and is often associated with liverworts. 
In the locality where the most luxuriant growth of Bryozi phium 
norvegium was found, Mnium punctatum is associated with it and 
grows on the vertical faces of the sandstone cliffs. 
Poly trichum piliferum Schreb. This small Poly trichum is 
common in the Sugar Grove region and occurs on exposed ledges 
of the sandstone. It is often found in association with one or 
more of the other Polytrichums but grows in more exposed places 
than any of the others. It is a common thing to find Polytrichum 
piliferum growing in very thin dry soil on the most exposed 
ledges of sandstone, while a little farther back where the soil is 
slightly deeper Polytrichum juniperinum grows, and still farther 
back in more sheltered places, Polytrichum commune or Polytri¬ 
chum ohioense. So far only sterile specimens have been collected,
