a few plants are found even here, growing in shaded soil 
about granitic cliffs. It is the northermost representa- 
tive of a small genus, most of whose species are of much 
more southern distribution.‘ It is probable that the 
fern is doomed to extinction in New Mexico, for the 
locality where it grows is a favorite spot for picnics, 
and ferns in such a place always suffer. 
31. Frurx rraciuis (L.) Underw. Perhaps our com- 
monest fern, common in all the higher mountains of 
the State, but only in the higher ones. It is not known 
from any of the low ranges of the southwest corner. 
32. WoopsiA MEXICANA Fée. Brazos Canyon, Upper 
Pecos River, Rio Pueblo, Sandia Mountains, Magdalena 
Mountains, Mogollon Mountains, Organ Mountains, 
Santa Rita, and White Mountains. On moist shaded 
cliffs, or rarely in exposed situations 
33. Woopsia scoputina D. C. Eaton. Brazos Can- 
yon (Standley) .* 
34. Woopsia PLuMMERAE Lemmon. Known only 
from the Burro Mountains, where it was collected by 
Dr. H. H. Rusby in 1881. 
35. MarsiLea vestira Hook. & Grev. Collected in 
the Guadalupe Mountains, near Queen, by Wooton. 
It was collected by Wright in the vicinity of El Paso, 
Texas, not far from the New Mexican border. 
[In the United States National Herbarium there is a 
specimen of Marsilea uncinata A. Br. obtained by one 
of the collectors of the Mexican Boundary Survey. 
The published report states that Dr. Bigelow collected 
the species somewhere in New Mexico. Althoug 
very small this specimen is probably correctly deter- 
mined, and possibly the species should be credited to 
the State.]
