Plants 20-110 cm; caudices branched, thick, and woody or rhizomes short, woody. Stems 1-30+, simple, sparsely to densely puberulent proximally to densely so in arrays. Leaves: basal and proximal winged-petiolate-subpetiolate (poorly differentiated), blades to winged petioles; blades oblanceolate, largest to 8 cm, usually smaller, gradually attenuate , margins entire, slightly undulate, sparsely to moderately soft-puberulent, somewhat viscid (stipitate-glands very small); mostly withering by flowering, new rosettes sometimes present; cauline petiolate (petioles 0.5-1 mm), blades (linear) elliptic proximally to (narrowly) lanceolate or ovate distally, largest 50-80 × 15-25 mm, reduced distally and becoming more ovate, 15-20 mm in arrays, margins entire or serrulate. Heads 1-140, not secund, in thyrsi-form-paniculiform arrays, sometimes compact, nearly as wide as tall, and rounded, sometimes appearing almost rounded corymbiform, proximal branches sometimes much elongate, not secund, spreading to ascending. Peduncles 0.5-5(-2.5) mm, densely short hispid-canescent, sparsely to densely stipitate-glandular, ± viscid; bracts small, grading into phyllaries. Involucres broadly campanulate, (3.5-)4-5(-5.5) mm. Phyllaries in 2-3 series, unequal, oblong to linear-lanceolate, acute to attenuate, sparsely to moderately strigose, especially distally, sparsely to densely stipitate-glandular, ± viscid. Ray florets 6-10; laminae ca. 3-5 × 1-2 mm. Disc florets 10-20; corollas 3-4 mm, lobes ca. 1 mm. Cypselae 1.5-2.5 mm, ± moderately short-strigose; pappi 3-4 mm. 2n = 18. Flowering Aug-Oct. Open oak-pine woods and rocky open slopes, disturbed ground; 1000-2700 m; Ariz., Colo., N.Mex., Okla., Tex.; Mexico (Chihuahua, Durango, Sonora, Coahuila). In T exas, Solidago wrightii grows primarily in the trans-Pecos region. It is one of the few usually obviously stipitate-glandular, viscid goldenrods; the stipitate glands are minute when present on other species. Two varieties have been recognized on degree of glandularity; these grade into each other to such a degree that their recognition does not appear warranted. The few plants seen from northeastern New Mexico and westernmost Oklahoma are possible variants of S. petiolaris, but overall they fit better in S. wrightii. A detailed morphometric study of this and the next two species is needed to resolve ambiguous species limits on the western Great Plains.

Duration: Perennial Nativity: Native Lifeform: Forb/Herb General: Herbaceous perennials, to 75 cm tall, stems simple, sparsely to densely puberulent proximally to densely so in arrays, plants with branched, thick, woody stems or short rhizomes. Leaves: Alternate, elliptic, 1-6 cm long, 5-25 mm wide, on winged petioles or nearly sessile, margins entire, slightly undulate, sparsely to moderately soft-puberulent, somewhat viscid, feather-veined or obscurely 3-nerved, relatively uniform in size and distribution. Flowers: Heads small, radiate, rays yellow, 6-14, pistillate, laminae 3-5 mm long, disk flowers yellow, perfect, 10-20, peduncles 0.5-5 mm, densely short hispid-canescent, sparsely to densely stipitate-glandular and viscid, bracts small, grading into phyllaries, involucres broadly campanulate, phyllaries unequal, densely puberulous, oblong to linear-lanceolate, sparsely to moderately strigose, especially distally, sparsely to densely stipitate-glandular and somewhat viscid, overlapping in 2-3 series, heads 1-many in dense or open panicles, not secund (borne only on one side). Fruits: Achenes 1.5-2.5 mm, moderately short-strigose. Pappus of capillary bristles, 3-4 mm long. Ecology: Found in open oak-pine woods and on rocky open slopes, disturbed ground, and pine forests; 3,500-9,500 ft (1067- 2896 m); flowering July-October. Distribution: AZ, s CO, NM, s OK, sw TX; south to n MEX. Ethnobotany: Unknown, but other species in the genera have uses. Etymology: Solidago comes from Latin solido, meaning to make whole or heal, while wrightii is named for Charles Wright (1811-1885) an American botanical collector.
