Unidentified Polemoniaceae

Submitted by KJvZ on
I photographed this species in Polemoniaceae in Utah, which seems to be some kind of Leptosiphon spec. Could anyone help me with the ID of this species? The location is the canyon of the Logan River, between Logan and Garden City in the Wasatch Range. Habitat is a limestone cliff at about 1700m.
Leptosiphon?
Leptosiphon spc.?
