the Susquehanna above Port Deposit. Two or three 
fronds from there have each a few areolate veins of 
exactly the same shape as those of Camptosorus. 
Asplenium ruta-muraria L. This was reported by 
Aikin, but has not since been found, although there are 
numerous outcrops of limestone in Baltimore Co. 
Dryopteris phegopteris (L.) C. Chr. This was listed 
by Aikin, but one would not expect to find it so far out 
of its range. For several years a special look-out was 
kept for it, and many plants of D. hexagonoptera which 
closely resembled it were found. 
Dryopteris Dryopteris (L.) Christ. In 1894 a little 
colony of this was found in a railroad cut about one mile 
from Towson. Although not two yards from the rails, 
they persisted there for years. Not listed by Aikin or 
Sollers. 
Dryopteris simulata Davenport. Enormous patches 
of this were found in October, 1894, at Glen Burnie, 
Anne Arundel Co., two months before it was described 
by Davenport. 
Dryopteris Goldiana (Hook.) A. Gray. Perhaps 
twenty-five plants, in two widely separated localities, 
have been found. Not listed by Aikin or Sollers. 
Dryopteris Clintoniana (D. C. Eaton) Dowell. <A very 
few plants doubtfully referred to this species, have been 
found. Not listed by Aikin or Sollers. 
Dryopteris Boottii (Tuckerman) Underwood. One 
Plant was found near the Gunpowder River, about 
twelve miles due north of Baltimore. It was in a road- 
side thicket and could not be found on a later visit. 
Another plant was found at Glen Burnie years ago. It 
was a large clump two years ago, owing to the branching 
of the rhizome. Not listed by Aikin or Sollers. 
Dryopteris spinulosa (Muell.) Kuntze. Not listed by 
Aikin or Sollers, but not uncommon. Vars. intermed- 
tum and dilatatum were listed by Aikin but not by Soll-
