1. Notholaena sinuata (Lag.)'Kaulf., Enum. Fil. 135. 1824. 



Acrostichwn sinuatum Lag. ex Swartz, Syn. Fil. 14. 1806. 



Canyons of the Colorado (Coconino and Mohave Counties), to the 

 mountains of Cochise, Santa Cruz, and Pima Counties, 3,000 to 7,000 

 feet; dry rocky slopes and crevices, often on limestone; very common. 

 Western Oklahoma and Texas to southern California; Mexico to Chile; 

 Jamaica; Hispaniola. 



This species is highly variable. A form with narrow blades and 

 small few-lobed pinnae is var. crenata Lemmon, having substantially 

 the same range in Arizona as the typical form, with which it intergrades. 

 It was long known erroneously as N. sinuata var. integerrima Hook., 

 a name properly belonging to a Mexican form. More recently it has 

 been described as N. cochisensis Goodding (Muhlenbergia 8: 93. 

 1912) on specimens from the Huachuca Mountains (Goodding 373).

Mountains, Pima County (Pringle in 1884), dry rocky slopes. West-
