47. Solidago confinis A. Gray, Proc. Amer. Acad. Arts. 17: 191. 1882.

Southern goldenrod

Solidago confinis var. luxurians (H. M. Hall) Jepson ; S. spectabilis A. Gray var. confinis (A. Gray) Cronquist

Plants 30—210 cm; caudices branching, thick, woody. Stems 1—10+, ascending-erect, glabrous, often short fascicles of leaves present at nodes in axes of distal cauline leaves. Leaves: rosettes present at flowering; basal and proximal cauline tapering to elongate, winged petioles, bases nearly sheathing stems, blades linear-lanceolate, 50—260 (including petiole) × 5—45 mm, somewhat fleshy (fresh), margins entire, faces glabrous; mid and distal cauline crowded (robust plants), sessile, blades linear-lanceolate to lanceolate, 20—130 × 5—10(—25) mm, reduced distally, margins entire, apices acute to attenuate, glabrous. Heads 70—320, usually not secund, in thyrsiform-paniculiform arrays, sometimes apically secund, 5—25(—50) × 2—14 cm; branches ascending to arching. Peduncles 2—8 mm, glabrous or sparsely strigose; bracteoles 1—3, distally grading into phyllaries . Involucres campanulate, 2.5—4 mm. Phyllaries in 3—4 series, linear-triangular, unequal, margins involute near tip, sharply acute, the outer 1 / 3 — 2 / 3 length of inner (1—3 × 0.4—0.9 mm), midribs usually enlarged and translucent. Ray florets 8—12; laminae 1—2.5 × 1 mm. Disc florets 10—20; corollas 3—4 mm, lobes 1—1.5 mm. Cypselae (narrowly obconic) 2 mm (5—7 broad ribs lighter than body), sparsely to moderately strigose; pappi 2—3 mm. 2 n = 18.

Flowering Jul—Oct. Wet stream banks, springs, marshes; 0—2500 m; Calif.; Mexico (Baja California).

Solidago confinis is similar to S. spectabilis and was treated by A. Cronquist (1994) as a variety of that species.
