68 PRETZ: FLoRA OF LEHIGH County, PENNSYLVANIA 
(?) Lycoprum PALMATUM (Bernh.) Sw. 
The published record for Lehigh County for this species is 
based on a specimen in the herbarium of the Philadelphia Botanical 
Club bearing a label which reads Carbon, Lehigh County. There 
is no Carbon in Lehigh County and Dr. Krout was very glad to 
correct this error when it was brought to his attention. The 
plant had been given to him. Mr. E. D. Leisenring reported this 
fern to Dr. Krout as occurring on the South Mountains south of 
Mountainville and a trip was made to locate this station. The 
fern was not found and though the habitat is promising, it likely 
never occurred in the county. 
The species occurs at a number of stations over the Pocono 
plateau and its extensions, from Monroe through Carbon and 
Luzerne counties as far as Schuylkill, with a record from Wyoming 
still farther north. It occurs also in Bucks and Philadelphia 
counties in Pennsylvania and at a number of stations in New 
Jersey, all however in the Carolinian. The only connecting station 
is apparently the one based on a specimen collected by Knipe 
at Delaware Water Gap in the herbarium at. the Academy of 
Natural Sciences at Philadelphia. The distribution of the species 
in this general region is not without interest. 
MATTEUCCIA STRUTHIOPTERIS (L.) Todaro - 
This record is now chiefly of historical interest. Dr. A. F. 
K. Krout found the ‘species well established at several places in 
the “Lowlands” along the Lehigh River at Coplay, but all were 
destroyed while he still continued a resident of the county, by 
the slag dumps of local iron furnaces. The stations in Northamp- 
ton County along Hokendauqua Creek and near Nazareth have 
also disappeared. 
_ The species is not rare in cultivation at Allentown, and recently 
the writer saw it planted about a Slatington residence. It is not 
unlikely that it may still exist in some isolated habitat in the 
county. The species is recorded southward at stations along the 
Delaware and can still be collected at places along this stream in 
Northampton and Bucks counties in Pennyslvania.

soils and formations. Has been recorded in one instance from a
