1903.) that Braunii finds its limit in that State. We 

 boast of the original station for Asplcnium ebenoides, 

 though it has long since been destroyed. Barring Ha- 

 vana Glen, Alabama, where ebenoides is abundant, 

 more plants have been found in Pennsylvania than in 

 any other State, an honor quite befitting the place of 

 its "botanical birth." In this connection it is of in- 

 terest to know that Scott was not the first to find As- 

 plcnium ebenoides. The Philadelphia Botanical Club 

 has recently acquired specimens accompanied by label 

 stating, "A fern collected by Airs. Adams near Lan- 

 caster, Penna., in 1860." Scott's single plant was 

 found in 1862. 



Growing in crevices of the rocks along Schuylkill 

 near (now in?) Philadelphia and not many miles from 

 the spot where Robert Robinson Scott found Asplen- 

 ium ebenoides, Thomas Nuttall, when the Nineteenth 

 century was yet young, discovered the fern he after- 

 ward named Asplcnium pinnaUfiduin- In apparently 

 the same general locality it still persists, known to a 

 few who guard it well. In 1815 Nuttall gathered a 

 quillwort along the Delaware river shore of the coastal 

 plain, which at the time, following the usual custom 

 was referred to the common European Isoetes lacus- 

 tris. Thirty years after, its distinctness was discovered 

 and the name it now bears, Isoetes riparia, was given 

 it by Dr. Engelmann. Further comments may be 

 found in connection with the various species. 



So varied and numerous have been the sources from 

 which I have drawn the information necessary in the 

 preparation of this flora, that it is rather difficult to 

 make adequate expression of my indebtedness and ap- 

 preciation to all. Dr. Porter's Bryophyta and Pterid- 

 ophyta of Pennsylvania, barring nomenclature, has
