 rounded: corolla barely surpassing the calyx, the straight and broad galea 

 about half as long as the tube; the lower lip 3-lobed, obscurely saccate, 

 more than half as long as the galea. On high dry plains, eastern Oregon

 acute, 1-2 inches long, upper ones somewhat larger, usually laciniately 

 lobed with 1 or 2 pairs of slender spreading lobes : bracts oblong, obtuse or
