General Information

Herbs, perennial; rhizomes creeping, branched. Stems to 150 cm tall, erect, simple, shortly and softly downy above. Leaves numerous, lanceolate or linear-lanceolate, 5-12 cm, abaxially downy, veins sparsely hairy, adaxially shortly pilose, tapering at both ends, margin of basal sometimes entire, of lower and upper cauline sharply serrate, longitudinal veins 3 (triplinerved), of which 2 lateral veins protrude weakly, apex acuminate. Capitula in paniculiform synflorescences, branches (racemes) curved downward, capitula attached on upper side of branch. Involucre 2.5-3 mm; phyllaries linear-lanceolate, slightly obtuse. Florets golden yellow; ray florets hardly longer than involucre. Pappus inner (longest) bristles not obviously clavate. Fl. Aug-Sep.

    Plants 30–150(–200) cm; rhizomes short to long creeping. Stems 1–20+, erect, glabrate proximally or sparsely strigoso-villous, becoming more densely so distal to mid stem. Leaves: basal 0; proximal to mid cauline usually withering by flowering, tapering to sessile bases, blades narrowly ovate-lanceolate, 50–190 × 5–30 mm, margins sharply serrate, 3-nerved, apices acuminate, abaxial faces glabrous or more commonly hairy along main nerves, adaxial glabrous or slightly scabrous; mid to distal similar, 30–50(–120) × 8–12 mm, largest near mid stem, reduced distally, margins usually serrate or serrulate (teeth 3–8), sometimes entire proximal to arrays. Heads (70–)150–1300+ , secund, in secund pyramidal-paniculiform arrays (obscurely so and club-shaped thyrsiform in small plants or shoots with small arrays), branches divergent and recurved, branches and peduncles hairy. Peduncles 3–3.4 mm, bracteoles 0–3, linear-triangular. Involucres narrowly campanulate, 1.7–2.5(–3) mm. Phyllaries in 3–4 series, strongly unequal, acute to obtuse; outer lanceolate, inner linear-lanceolate. Ray florets (5–)8–14(–18); laminae 0.5–1.5 × 0.15–0.3(–0.5) mm. Disc florets (2–)3–6(–8); corollas 2.2–2.8(–3) mm, lobes 0.4–0.8(–1) mm. Cypselae (narrowly obconic) 1–1.5 mm (ribbed), sparsely strigose; pappi 1.8–2.2 mm.

    Solidago canadensis L., Sp. Pl. 878. 1753; S. altissima L.

    Hierbas perennes, rizomatosas hasta 1.5 m de alto; tallos erectos, rígidos, frágiles, teretes, con pubescencia densa y corta, verdes a purpúreos. Hojas alternas, numerosas y densamente agrupadas a lo largo del tallo, angostamente ovado-elípticas a oblanceolado-elípticas, 4–10 cm de largo y 0.5–1.7 cm de ancho, márgenes algo dentados a enteros, pubescentes pero más así en el envés. Capitulescencias espiciforme-paniculadas, terminales, ramas inferiores con frecuencia recurvadas o arqueadas; capítulos radiados, numerosos, ca 4 mm de largo; involucros campanulados; filarias en 3–4 series, lineares a linear-lanceoladas, ápice agudo a obtuso, márgenes escariosos; flósculos del radio 5–8, las corolas amarillas, las lígulas lineares, 2–3 mm de largo, enteras o profundamente 1–2 lobadas; flósculos del disco 12–14, las corolas tubulares, ca 4 mm de largo, amarillas. Aquenios angostamente obpiramidales, ca 1.2 mm de largo, pubescentes; vilano de 45–55 cerdas, ca 3 mm de largo, ciliadas, blancas.

    Conocida en Nicaragua por una colección (Lara 121) realizada entre San Marcos y Masatepe, Masaya; fl y fr sep–dic; nativa de la región templada de Norteamérica pero ampliamente introducida en otras partes como pastizales y malezas, siendo muy constantes, formando clones por reproducción vegetativa. Un género muy grande, difícil, en general de las regiones templadas del mundo, con quizás 150 especies estrechamente afines.
