Primulas of Columbia Plateau

Most common and widespread are P. conjugens and P. pauciflora.

One distinguishing trait is the way the flower tubes join near their top just below (distal to) the petals:
smoothly connected, appearing almost merged into a cylinder is P. pauciflora (https://www.inaturalist.org/observations/153265869)
clearly separated with deep clefts between them is P. conjugens (https://www.inaturalist.org/observations/153265811), which is also less common, or at least less often observed on iNat, and never on the west side (which sounds opposite, presumably conjugens doesn't refer to the tube joins)
