Astragalus lentiginosus var. Coulteri (Benth.) Jones Cont. 8 4 

 (1898). A. Coulteri Benth. PI. Hartweg. 307 (1848). A. Arthu-Schotti Gray. 

 A. eremicus Sheldon. Pods rigid, not leathery nor papery, hoary as is 

 the whole plant, about 2 cm. long, very oblique and falcate-short- 

 pointed. Flowers about 1.5 cm. long, wide, the subulate calyx teeth 

 nearly as long as tube. Leaflets often 2 cm. long. Pubescence great- 

 est on the under side of the leaflets. Common on the Colorado 

 and Mojave deserts, and Owen's Valley California. Tropical. On 

 flat and gentle slopes. Biennial. This is almost certainly a hy- 

 brid between lentiginosus and aridus.

 66 (1871). A. Fremonti T. and G. Pac. R. R. Rep. 4 80 (1857). A. 

 Coulteri var. Fremonti' (T. and G.) Jones. Pods translucent and 

 papery and smooth, oval-ovate with a more or less falcate tip, 2-3

 none except a little spreading hairs on stems, peduncles and rachis. 

 Stems very stout, 2-3 ft. high, erect, biennial, blooming as winter 

 annuals. Yucca Arizona, Jones. Tropical. Similar material from 

 Good Springs and Meadow Valley Wash Nevada but with elongated 

 banner and wings and calyx teeth subulate and one third as long 

 as tube. Other material similar but with coriaceous pods from Peach

 intergrading toward the var. Mokiacensis. Other material from Chlo- 

 ride Arizona with the flowers of Mokiacensis but otherwise the var. 

 Yucanus.
