This widely distributed southern fern, although 
occurring in the Ozark region of Arkansas and Missouri, 
appears to be absent from a large area in eastern Texas, 
the isolated station near Houston being very excep- 
tional. In the canyons of the Edwards Plateau it 
grows in great luxuriance and abundance on the rocky 
margins of pools and limestone bluffs and ledges, kept 
perennially wet by seeping springs. The Houston 
station, discovered by Mr. Geo. L. Fischer, is along 
a deep, shaded spring branch, where there is an outcrop 
of somewhat calcareous Quaternary sandstone. In 
Randall and Armstrong Counties it is found, rarely, 
in deep spring-fed canyons, growing upon shale and 
sandstone of Triassic age.
