PAYSON—MONOGRAPH OF THE GENUS LESQUERELLA 
Colorado: south of Trinidad, Las Animas County, July 21, 
1918, Osterhout 5781 (Geo. Osterhout Herb.); Trinidad (road to 
Walsenburg), June 20, 1917, Johnston 976 (Geo. Osterhout 
Herb.); Silverton, July 10, 1895, Tweedy 147 (U. S. Nat. Herb.). 
New Mexico: dry hills on and near the Sierra Grande, Union 
County, June 20, 1911, Standley 6249 (U. S. Nat. Herb., TYPE); 
dry hills, vicinity of Raton, Colfax County, June 21 and 22, 
1911, Standley 6294 (U. S. Nat. Herb.). 
This variety is characterized by an excessive development of 
the caudex and by the more silvery, larger basal leaves which 
are usually toothed. The specimen from Silverton, Colorado, 
is the only one seen from west of the Continental Divide and is 
nearly, if not quite, typical.
