Stems (4–)8–28 cm. Leaves: basal and proximal cauline (12–)16–52 × 5–14 mm; cauline 11–52 × 3–12 mm, blade lanceolate to oblanceolate or elliptic. Thyrses 2–13 cm, verticillasters (2 or)3–5. Flowers: calyx lobes rarely lanceolate, 1.2–2.4 × 0.6–1.3 mm, apex truncate to obtuse or mucronate, rarely short-caudate or acute; corolla 7–10 mm; pollen sacs 0.4–0.6 mm; staminode glabrous or distal 0.5 mm sparsely pilose, hairs yellow, to 0.4 mm.
Phenology: Flowering Jun–Jul.
Habitat: Gravelly alpine slopes.
Elevation: 2700–3200 m.
Discussion
Variety modestus is known from the East Humboldt and Ruby mountains of Elko County. Specimens from the Toquima Range in Nye County, which are here referred to var. formosus, bear short (1–1.5 mm), truncate to mucronate calyx lobes that are typical of var. modestus, but they are more similar to var. formosus in habit and inflorescence characters.
Selected References
