Throughout its range in Texas this fern is usually 
found growing on trees, and apparently it has little 
preference as to species, providing they grow in mod- 
erately shaded and damp situations and have a rough, 
porous bark and wide-spreading or horizontal branches 
or inclined trunks, where the spores can find lodgment 
while germinating and a supply of moisture for some 
time after rains. Near the Gulf Coast the Live Oak 
(Quercus virginiana) serves its requirements most ad- 
mirably, and it is often found upon species of Tra. 
Occasionally it is found growing on rocks, where the 
spores have found lodgment amongst moss or lichens. 
The specimens from Larissa were found on ferrugineous 
sandstone boulders, and those from Riverside on sand- 
stone bluffs.
