19. Pentaza scaBra C. Chr. [P. aspera (Hook.) 
Baker]. Known only from the “Copper Mines” (Santa 
Rita), a classic locality for New Mexican plants, where 
Wright and Bigelow collected the types of many common 
southwestern species. This fern was collected here by 
both these collectors, in the early fifties, but it has not 
been found in the State more recently. 
20. PELLAEA ATROPURPUREA (L.) Link. Black Range, 
San Luis Mountains, Bear Mountain, Florida Moun- 
tains, Mangas Springs, Organ Mountains, Guadalupe 
Mountains, and on the highest point of the Llano Es- 
tacado. In the Organ Mountains it grows under thickets 
among granitic rocks, but elsewhere it usually frequents 
crevices and ledges of limestone cliffs. 
21. PELLAEA PULCHELLA (Mart. & Gal.) Fée. 
Collected in New Mexico but once, in the Guadalupe 
Mountains near Queen (Wooton), in crevices of lime- 
stone rocks. This beautiful little fern is abundant in 
the region mentioned and is evidently very much at 
ome. 
22. PELLAEA TERNIFOLIA (Cav.) Link. Specimens 
possibly referable here were collected in the Organ 
Mountains by Wooton in 1891. It is possible that 
they are only a depauperate form of P. mucronata, for 
the species has not been found since in this range, al- 
though much collecting has been done there. Dr. 
Underwood reported it from Socorro (Plank), and Mr. 
M. E. Jones states that he found it at Silver City. 
The species is not uncommon in Chihuahua, and there 
is every reason for expecting it in New Mexico. 
23. PELLAEA MucRoNATA (D. C. Eaton) C. Chr. 
[P. Wrightiana Hook.]. Sandia Mountains, Socorro, 
Santa Rita, Burro Mountains, Florida Mountains, and 
Dona Ana and Organ Mountains. Common at low 
altitudes. The type of P. Wrightiana was collected by 
Wright (No. soe at Banta Since or at least the Wright
