Plancia ëd Artemisia spiciformis Osterh.

Descrission:

Ann Howald brought this taxon to my attention. After studying this region for decades, Ann started paying attention to what looks a lot like Artemisia tridentata, and hence easily passed over. In the TJM2 key, this taxon keys out next to A. tridentate at the end of the Artemisia key. Ostensibly the key break is 'Leaves entire to irregularly 36-toothed, partly deciduous; plant sprouting from roots; moist slopes, rocky meadows, High Sierra Nevada, White and Inyo Mountains > 2000 m.'
