Discussion

Of conservation concern.

Variety obovatum is known only from the Greenhorn and the San Bernardino mountains (M. Skinner and B. Pavlik 1994). It is apparently entirely diploid (J. S. Mooring 1975) and is suspected of forming natural hybrids with Eriophyllum confertiflorum (L. Constance 1937). The scarcely distinguishable var. lanceolatum is disjunct by 800 km northward.
