There was at least one small area with many of these, probably Lomatim lithosalamans.
On extreme lithosol that supports few species, even Artemisia rigida is stunted or absent. I found Lomatium quintuplex, Poa secunda, Lewisia rediviva, Phemeranthus spinecens, and probably Idahoa scapigera fruits.
Is purple normal for these? The other plants didn’t show it.
