Annual, perennial herb, glabrous.
Leaf: basal, cauline, opposite.
Inflorescence: flower 1 per stem or branch.
Flower: parts in 4s; calyx tube distinct, lobes lanceolate, acuminate; corolla funnel-shaped, blue (white), lobes <= tube, oblong to elliptic-obovate, obtuse or rounded, ± entire to serrate, jagged, or fringed, without fringes or scales on adaxial surface, nectary pits 0 (nectaries on corolla tube near base); ovary stalked, style short or indistinct, persistent, entire, stigmas 2.
± 15 species: temperate North America, Eurasia. (Greek: resembling Gentiana) Gentianopsis thermalis (Kuntze) H.H. Iltis occurs near CA, in NV.
Unabridged note: Efforts should be made to find in CA Gentianopsis thermalis (Kuntze) H.H. Iltis [Gentianopsis detonsa (Rottb.) Ma var. elegans (A. Nelson) N.H. Holmgren] (stems 1–several, generally branched; basal leaves generally present at flower; corolla (20)35–75 mm, lobes proximally fringed, distally dentate), which occurs very near the state line in NV (Washoe County; Lake Tahoe, creek at Incline, alt. 6200 ft., sandy beach along stream).
