This species differs from F. rupicola chiefly in the peculiar irregularly 

 branched hairs which form a grayish white tomentum on the under side 

 of the leaves interspersed with long strigose hairs ; the upper surface of the 

 generally oblong leaves is more or less scabrid and the margins usually 

 revolute. Fendlera tomentella Thornber I am unable to distinguish from 

 F. Wrightii. This species ranges from southwestern Texas to southwestern 



Arizona

The lcx;ality and the dales of Wright's Nos. 728 and 1381 are here given according to 

 his field notes preserved in the hhrary of the Gray Herbarium. A. Gray in Plantae 

 Wrightianae, 1. c., gives " crevices of rocks of the San Pedro River " as the locality. San 

 Pedro River is another now obsolete name of the Devil's River.
