Sida 10: 178, figs 2, 3. 1983.

Common names: High-plains goldenrod
Endemic
Treatment appears in FNA Volume 20. Treatment on page 154. Mentioned on page 110, 150.

Plants 30–100 cm; caudices woody, rhizomes elongate, branching, woody, forming new centers of growth. Stems 1–20, erect, finely scabroso-puberulent, sparsely so with age proximally, densely so distally. Leaves: basal and proximal cauline withering by flowering, subsessile, gradually tapering to short-winged petiolelike bases; mid and distal cauline sessile, blades linear-elliptic to linear-lanceolate, 40–90 × 4–5 mm, 3-nerved from base, midnerves prominent, margins entire, finely scabrous, apices attenuate-acute, faces finely, sparsely to moderately strigose, more so on main nerves, finer nerves translucent, faces sometimes shiny. Heads 25–350, in short-to-elongate, secund paniculiform arrays, branches ascending or ascending and distally recurved, sometimes second, sometimes elongate. Peduncles 2–6 mm, finely strigose; bracteoles 1–10, often crowded, linear-lanceolate, 2–3 mm, grading into phyllaries. Involucres narrowly campanulate, 3.5–4 mm. Phyllaries in 3–4 series, linear-lanceolate, strongly unequal, margins hyaline, distally subulate-ciliate, apices acute, glabrous. Ray-florets 4–5; laminae 1.5–2.5 × 0.5 mm. Disc-florets 6–8, 3–3.5 mm, lobes 0.5 mm. Cypselae (narrowly obconic) 1.5–2.5 mm, sparsely strigillose; pappi 3 mm. 2n = 18.


Phenology: Flowering Sep–Oct.
Habitat: Mixed gypsum and shale soils, rocky slopes, escarpments, and ridges in high plains
Elevation: 400–1200 m
