nectary small; styles lU-12 mm. lonj;, widely spreading in 

 fruit; fi>llicles viscid-puberulcnt, lU-14 mm. lung. 



Only one specimen has been seen. That is Mr. Clute's 

 no. 52, collcclecl on wet rocks, 5000 feet altitude, Navajo 

 C'reek. .\rizona, July 9tli-August 24th, 1919. According to 

 .\lr. (.'lute's notes this is a rare plant with white and pink 

 Howers and vivid foliage. It commonly grows in the crevices 

 of shaded rocks and was also found at Betatakin antl on the 

 road to I^'arniington. 



Tile most outstanding features of this plant are the 

 (luadriternate leaves and the very viscid foliage. In the 

 herbarium the sand is still clinging to the entire plant surface. 

 The deeplv divided leaves are reminiscent of A. Boshcoodiae 

 Rvdb. which is also remarkably \iscid. From the litter 

 the new species is easily distinguished by the i)ink sepals, 

 the normal and regular spurs and by the more deeply divided 

 leaves. It seems probable that A. nai'ajoiiis is in reality most 

 closely related to A. tritcrnafa Payson. That species has 

 triternate leaves and the plant surface is scarcely viscid.
