Key to subspecies (after Veno, 1979):

Nutlets planar or with apices somewhat recurved, linear-oblanceolate, homomorphic to slightly heteromorphic, length/width= 5/1 (-4/1);
   margin erect to strictly ascending, (cleft-) divided dentate; margin teeth less than two times longer than wide;
   North America, coastal California and Baja California Norte, Mexico; South America, Argentina (rare Chile) ... P. ferocula [=P. linearis subsp. ferocula]
Nutlets moderately recurved, oblanceolate, heteromorphic with the lower or both adaxial nutlet margins and/or nutlet size reduced, length/width= 4/1 (-3/1);
   margin sub-involute to ascending; margin teeth wide, two or more times longer than wide.
      Plants erect to ascending (-decumbent); nutlet margins strictly to widely ascending, broadly and regularly cleft to parted dentate;
         North America, southeastern California, Arizona, and Sonora, Mexico ... P. platycarpa
      Plants prostrate to decumbent; nutlet margins sub­ involute to erect to ascending, often medial­laterally constricted, irregularly parted to divided dentate;
         South America, Chile, rare Argen- tina ... P. linearis
