Other Specimens Examined: 



Sinaloa: Lodiego, October, 1891, Palmer 161 6. On road between 

 Rosario and Colomas, July 13, 1897, -^^^^ 3186. 



Oaxaca: Chicapa, February 17, 1904, Goldman 738. 



This species, whose range partly overlaps that of 5. humilis, is 

 most closely related to that species, but may be distinguished by 

 its much larger leaflets which are usually, long cuspidate. vSeeds 

 collected by Palmer under his no. 16 16 are not distinguishable 

 from those of 5. humilis, but are too fragmentary to afford any 

 measurements.
