Antennarias are the characteristic plants this is the "white" 

 period in the dry grassland. None of the vegetation reaches 

 to a height of 2 dm., little rises even 1 dm. and most is close- 

 lying. Carex stenophylla forms a loose sod. Its small, capitate 

 inflorescences are raised about 5 or 6 cm. above the ground. 

 This plant is frequent in nearly all of the societies of the 

 dry grassland but especially those where conditions are hyper- 

 xerophytic.

flower: Aragallus lanibertii, Antennaria anaphaloides, A. rosea 

 and A. micropJmjlla, Comandra pallida, Sedum stenopetalum, 

 Eriogonum umheUatum. This is a "red, white and yellow" 

 period. The Aragallus, or red loco, covers wide stretches, 

 acres in extent, conspicuous from any vantage point within 

 the park or on the surrounding hills. Where the glacial topog- 

 raphy remains the loco is found chiefly on knoll-tops. It 

 occurs especially on east exposures and to the north and south, 

 showing a distinct tendency to be absent from the west slope
