Johnson, Leigh A., Chan, Lauren M., Burr, Kirsti & Hendrickson, Dallin, 2012, Navarretia furnissii (Polemoniaceae), a new diploid species from the intermountain western United States distinguished from tetraploid Navarretia saximontana, Phytotaxa 42, pp. 51-61 : 58-59

Navarretia saximontana S.C. Spencer (2003: 198) , sp. emend.

Plants as per the original description, with the longest two calyx lobes mostly entire, infrequently 2–3 pronged. Corolla 4.8–6.2 mm long, lobes 0.4–0.8 mm wide, 0.6–1.1 mm long. Stamen filaments 0.4–1.2 mm long, inserted 0.6–1.2 mm below the sinuses. Tetraploid.

Although widely distributed, our surveys indicate that type locality is the only known population within the state of Utah—with all other putitive populations representing N. furnissii .
