Asplenium, Linneus. SpLeENWorT. 
9. A. Trichomanes, Linneus. Fish mentions as a station for 
this rare fern, “near Irondequoit Bay, east of the Float Bridge.”’ Fuller 
says, ““same ravine as Campéosorus.” Prof. Lennon found it in the 
ravine at Holley. It grows somewhat freely on the rocky walls of 
Watkins’ Glen. 
10. A. ebeneum, Aiton. The writer discovered a single plant 
of this species in the summer of 1882, near the “ Sea Breeze,” on the 
grounds of the summer resort of F. S. Rew. A natural growth of trees 
remains on the place, and under one of the trees was growing this 
Black-stalked Spleenwort. As it was known to be rare here the spot 
was carefully noted, and the following year another visit was made to 
see it and it was found to be there as previously. The third summer the 
place was again visited, and, although the spot being well known was 
found, there was no trace of the cherished plant. It is believed that 
this is the only specimen of the species ever seen very close to Roch- 
ester, and the only other reported is in the ravine at Holley, collected 
by Professor Lennon. 
11. A. montanum, Wildenow. Absent. 
12. A. Ruta-muraria, Linneus. Absent. 
13. A. angustifolium, Michaux. This species is not found 
plentifully here. It formerly grew in a piece of rich woods east of the 
city. Fish mentions it as “not rare’’ west of the city, in the town of 
Gates. On low ground, not far from the entrance, in the “Glen,” at 
Seneca Point, on Canandaigua Lake, it grows in some profusion. The 
writer has carefully looked over hundreds of plants there, as well as at 
the first station mentioned above and elsewhere, but has never had the 
good fortune to find a fertile frond of it. 
14. A. thelypteroides, Michaux. The Silvery Spleenwort is 
common in rich woods and thickets. 
15. A. Filix-foemina, Bernhardi. A common species, and well 
distributed throughout our region in rich woods. 
Scolopendrium, Smith. Harrs Toncue.
