A New NorHouaENA 107 
ing words, his discovery of a fern new to the United 
States: “At our nooning place, having reached an eleva- 
tion of not less than one thousand feet above the valley 
of the Virgen, a deep gorge in the limestone rocks af- 
forded a scant supply of water. In the abrupt face of 
these perpendicular rocks, a delicate fern was noticed, 
which Prof. Eaton has determined to be identical with 
the Notholaena tenera Gillies, from the South American 
Andes, not before found in North America. Owing to 
the shortness of our stay and the difficulty of securing 
Specimens from the inaccessible positions in which they 
grew, only scanty collections were made, but the local- 
ity is so readily identified that some future botanist will 
be able to supply the demand for this interesting addi- 
tion to North American Filices.”2 In the concluding 
Paper (p. 351) the locality data are stated more defin- 
itely, as follows: “Crevices of perpendicular limestone 
rocks in a deep ravine near the base of Beaver-dam 
Mountains, twelve miles southwest of St. George,” with 
brief comments by Eaton, these comparing the Utah 
Plants with South American material. Notholaena 
tenera was originally described from Argentine speci- 
mens,’ and had been known previously only from the 
Andes of South America. 
In ‘Ferns of the Southwest”! Eaton published a de- 
scription of “‘ Notholaena tenera,’” basing it chiefly upon 
southern Utah plants, additional specimens of which 
Were said to have been collected by Dr. Edward Palmer 
in 1877. A short time later, in the Ferns of North 
America,’ Eaton figured the Utah plants as N. tenera; 
and though expressing some doubt as to their proper
