Here's some examples of native species found in these plant communities:

Bouteloua gracilis (Blue Grama) - the eyelash grass!  Notice the yellow sweetclover peaking in the southeast corner.
 
 

    Oenothera (Primrose) - a common weedy species
 

Pentaphylloides floribunda (Shrubby Cinquefoil) - reponds well to fire
 
 

Epilobium angustifolium (Fireweed) - a pioneer species that thrives in disturbed areas
 

Penstemon - lots of varieties found here
 

Castilleja miniata (Indian Paintbrush) - late bloomers, found in open understory of Ponderosa forest and meadows
 

Antennaria (Pussytoes) - beautiful ground cover, abundant in these montane communities
 
 

And many, many more.  I found over 150 species in my study plots alone.
