G. L. Nesom (1993b) merged Solidago californica, S. sparsiflora, and S. velutina without recognizing any infraspecific taxa, as did A. Cronquist (1994). J. C. Semple et al. (1990) compared S. californica and S. sparsiflora to S. nemoralis and found that all three are significantly different in a multivariate analysis. Evidence for separating the two subspecies of S. nemoralis was greater than the support for separating S. californica and S. sparsiflora.

Description

provided by eFloras
Plants (forming diffuse clones) 15–80 (–150) cm; rhizomes creeping, slender. Stems 1 (at ends of rhizomes), ascending to erect, glabrate proximal-ly to sparsely to densely strigoso-puberulent distally. Leaves: basal and proximal cauline often persisting to flowering, gradually tapering to winged petioles, blades linear oblanceolate to oblanceolate, rarely spatulate, 50–120 × 8–30 mm, proximalmost much smaller, margins entire to sharply serrate, faces glabrate to moderately scabroso-strigose; mid and distal cauline sessile or subsessille, blades elliptic to oblanceolate or obovate, 10–50 × 3–12 mm, mid tapering to bases, somewhat to strongly 3-nerved, largest, usually much reduced distally, margins entire or sometimes distally serrate, apices acute, faces sparsely to densely strigoso-puberulent, sometimes softly so. Heads (2–)30–500, in narrow to broad, thyrsiform to secund-pyramidal paniculiform arrays, branches recurved, secund, congested to lax. Peduncles 1–6 mm, sparsely to densely strigillose; bracteoles 0–5, sometimes clustered near to and grading into phyllaries, linear-lanceolate. Involucres campanulate, 3.5–6 mm. Phyllaries in 3–5 series, lanceolate to oblong, strongly unequal, acute or sometimes obtuse, glabrous or sparsely strigillose. Ray florets 6–12; laminae 2.9–6.3 × 0.3–0.7(–1) mm . Disc florets 5–17; corollas 3.5–6 mm, lobes 0.8–1.7 mm. Cypselae 0.7–2.7 mm, sparsely to densely strigillose; pappi 2.5–4.7 mm.

Solidago velutina

provided by wikipedia EN

Solidago velutina, the threenerve goldenrod[2] or velvety goldenrod, is a plant species native to Mexico and to the western United States. The species has been found in southwestern Oregon, east to the Black Hills of South Dakota, and as far south as México State in the central part of the Republic of México.[3][4][5][6] It is classified as a member of Subsection Nemorales.[7][8]

Recent taxonomic treatments have expanded the concept of S. velutina to include S. californica and S. sparsiflora, long considered by many to be distinct species.[3][6] These are now often treated as subspecies:[3]

  • Solidago velutina subsp. californica (Nutt.) Semple - California, Oregon
  • Solidago velutina subsp. sparsiflora (A.Gray) Semple

Another infraspecific taxon is also recognized by some authors:[1]

  • Solidago velutina var. nevadensis (A. Gray) C.E.S. Taylor & R.J. Taylor

Description

Solidago velutina has a basal rosette of leaves that are still present at flowering time. The leaves get progressively smaller higher up on the stem. Each leaf has three prominent veins running from the base to near the tip. One plant can produce as many as 500 small yellow flower heads in a large, branching array at the top of the plant.[3]

Galls

This species is host to the following insect induced galls:
