Coordinator notes: Based on field marks this should be a sheridanii subspecies, but I do have some dumetorum from the Mt. Whitney Portal area at that mountains base in Inyo County, California that can look just like sheridanii. I suspect that there are some localities where there may be some interbreeding. Both species seem to occur on the east side of the Sierra Nevada in Inyo and Mono Counties in California. Identifying "greenies" in Oregon and Washington can be difficult with sheridanii, dumetorum and affinis all occurring in that region-Ken Davenport
