short, bifid. Capsules smooth, carpels 

 carinate; seeds sharply quadrangular, 

 slightly to manifestly rugose between the 

 angles, the rugae sometimes so obtuse as 

 to make the surface appear shallow pit-

 Variety CONSANGUINEA Boiss. 



Differs from the species in having a 

 more erect growth; an obtuse sharply ser-

 seeds less sharp on the angles; and more 

 or less red coloration in the stems and 

 leaves." Millspaugh, Pittonia 2:84.

 Variety RUGULOSA Engelmann. 



"Differs principally in its thickly mat-

 down the longer side of the leaf; and the 

 turgid very finely rugulose seeds. The 

 type from San Bernardino. Calif., S. B. 

 & W. P. Parish, 1881." Millspaugh, Pitt-

Variety NEO-MEXICANA Millsp. 



"Erect, glabrous, with acutely angled

 lobes entire or 2-3 cleft." Millspaugh,
