Intergrades between the species and the variety hirteUiis are 

 abundant, especially in the southern dry interior portion of the state. 

 Here the specific and varietal characters, including pubescence, shape 

 and texture of leaflets, size of pods and seeds, appear in various com- 

 binations and it is often extremely ditKcult to determine Avhether a 

 given plant belongs to the species or to the variety. It is among these 

 intergrades that L. nudiforus Greene may be found. Intergrades 

 between the species and the A'ariety hirtelhis: Santa Rosa Island.
