11. Solidago juncea Aiton (early goldenrod)

S. juncea f. scabrella (Torr. & A. Gray) Fernald

Pl. 243 c–e; Map 1000

Plants with the rootstock usually relatively short, stout, horizontal, branched, and often rhizomatous, sometimes also with deep-set, longer-creeping rhizomes. Stems 1 to few, 30–120 cm long, erect or ascending, with several fine, longitudinal lines or grooves, glabrous below the inflorescence (rarely sparsely and inconspicuously hairy along the inflorescence branches), not shiny, not glaucous. Leaves basally disposed and usually persistent at flowering (additional rosettes often present adjacent to the flowering stem). Basal and lowermost stem leaves with the blade 8–20(–35) cm long, 1.5–4.0(–8.0) cm wide, mostly 5–8 times as long as wide, narrowly oblanceolate to narrowly elliptic-obovate, not or only slightly thickened, tapered gradually to the winged petiole at the base, angled or tapered to a sharply pointed tip, the margins finely to coarsely and sharply toothed, microscopically roughened or minutely hairy, the surfaces glabrous or rarely sparsely roughened or with a few softer hairs, the undersurface with 1 main vein, the fine, pinnate secondary veins usually easily observed (these and the veinlets forming an irregular, dense network). Median and upper stem leaves 2–12 cm long, lanceolate to narrowly elliptic or nearly linear, sessile or short-petiolate, otherwise similar to the lower stem leaves. Inflorescences relatively dense and narrow to relatively open and broad, pyramidal panicles (the lower branches sometimes elongate), the longer branches and often also the tip arched or nodding, the heads oriented upward along the branches. Involucre 3–5 mm long, the bracts in 3 or 4 unequal series. Involucral bracts oblong-ovate to narrowly oblong or narrowly lanceolate and bluntly to less commonly sharply pointed at the appressed-ascending tip, the thin, white to yellowish white margins sparsely hairy toward the tip, the outer surface glabrous, with a poorly differentiated green to light green central region above the midpoint, this tapered gradually to the midvein, the midvein not or only slightly thickened, and no additional veins present. Receptacle usually with a few chaffy bracts (similar to the involucral bracts but somewhat shorter) toward the margin. Ray florets 7–12, the corollas 2.0–2.5 mm long, yellow. Disc florets 8–15, the corollas 2.5–3.5 mm long, the lobes 0.5–0.8 mm long, yellow. Pappus 2–3 mm long, some of the bristles slightly thickened toward the tip. Fruits 1.0–1.5 mm long, obovoid, sparsely hairy or rarely glabrous. 2n=18. June–October.

Scattered in the southern half of the state and in the northeastern quarter (eastern U.S. west to Minnesota and Louisiana; Canada). Upland prairies, glades, savannas, and openings of mesic to dry forests; also railroads, roadsides, and open, disturbed areas.
