KINGMAN: CALIFORNIA FERNS 39 
The maidenhair ferns are found in damp, shady places, 
often in springy ground. There are several species, the 
commonest being Adiantum emarginatum Hook., with 
broad fronds and rounded pinnules. This species matures 
quite early in the spring and then turns brown. I have 
collected it at Pasadena and Santa Barbara, and also 
on Catalina Island, where it is eee on the hills 
overlooking the ocean. 
I have not pana Adiantum inlet (Kaul) 
Fée common at Pasadena, but I have collected fine speci- 
mens of it near Santa Barbara. In the Ojai Valley, in 
Ventura County, I once found a large patch of this fern 
so thick that I was obliged to tread on hundreds of the 
a plants jin order to walk up the canyon. This species 
differs from A. emarginatum in its longer lanceolate 
fronds and in the more wedgeshaped pinnules, which 
are more lobed on the upper margin; and it matures later, 
so that fresh fronds may be gathered late in the summer. 
Among the larger ferns is sexlragmea argutum Kaulf. 
This is an evergreen fern, r bling A. marginale of the 
eastern states both in form and texture. It is oo com- 
mon on the shady sides of canyons. 
Polystichum munitum (Kaulf.) Und. is one of ie oe se : 
finest of our western ferns, and is found in the upper can-_ a 
: yons. It resembles the Christmas fern but is much larger a 
in every way, the fronds being | two. or three feet Seg and
