[taxon report][distribution map][all photos][line drawing]
(Guadalupe Mountains goldenrod)
Scientific Name: Solidago wrightii A. Gray var. guadalupensis G.L. Nesom
Vernacular Name: Guadalupe Mountains goldenrod
R-E-D Code: 2-1-2
Description: Subrhizomatous clumped perennial herb; stem 3-7 dm long, ascending to erect; upper stems sparsely to densely hirsute, eglandular; leaves alternate, lanceolate, 3-6 cm long, 4-7 mm wide, narrowly lanceolate to linear-lanceolate on the upper plant; inflorescence subcorymboid 3-6 (-9) cm long and broad; heads 9-12 mm wide; rays about 4 mm long, 2 mm wide, rather large and showy for members of Solidago; phyllaries glabrous to minutely sessile-glandular; achenes mostly glabrous (rarely strigose). Flowering June to August.
Similar Species: Solidago wrightii var. guadalupensis can be distinguished from other taxa treated within S. wrightii by its narrow lanceolate leaves (3-6 cm long by 4-7 mm wide as compared to 3-6 cm long by 10-15 mm wide in other taxa) and mostly glabrous achenes.
Distribution: New Mexico, Chaves and Eddy counties; Texas, Culberson County.
Habitat: Limestone outcrops and substrates, most commonly associated with the following vegetation types: acacia-juniperus-dasylirion-lechuguilla, oak, oak-maple, and yellow pine-maple-hophornbeam-madrone; 1,340-2,200 m (4,300-7,100 ft).
Conservation Considerations: The taxon occurs in just two broad population systems. Additional field work is needed to determine abundance and potential land use impacts.
