Woodsia scopulina D. C. Eaton. Upon the summits 

 of rocks, usually in exposed places, this species is common. 

 Where they are exposed to the direct rays of the sun the 

 plants are dwarfed, but in protected situations they 

 attain a height of 18 cm. 



Woodsia mexicana Fee. On a shaded cliff a form 

 which differs somewhat from the typical one, but referred 

 here for the present, was collected. Woodsia mexicana, 

 so-ealled, is the common Woodsia of the State. 



Filix fragilis (L.) Underw. Although one of the

 usually drooping from crevices of cliffs. The fronds 

 were unusually large and finely dissected.

 the aspens, were a conspicuous feature of the hillsides. 

 Many of the fronds were infested with what appeared to 

 be a fungus.
