Achillea borealis  Bong.  ssp. californica  (Pollard) Keck

Ubiquity: Very uncommon

Distritution: Only in the Napa Marsh

Plant Communities:  Coastal Salt Marsh

Habitats:  Moist, sunny, saline, marshy areas; occasionally on berms; in alluvial areas

Elevations:  5-10'

Comments:  = A. millefolium in new Jeps.  Perhaps better named A. puberula Rydb. or A. millefolium L. var. puberula (Rydb.) Nobs. in Ferris.  Clasping, decurrent leaf bases seem to distinguish this taxon from A. millefolium
