Lorandersonia salicina is sometimes treated as a variety of Hesperodoria scopulorum or as a distinct, atypical species in that genus (G. L. Nesom 1991f). Phylogenetic analyses (R. P. Roberts and L. E. Urbatsch 2004) relate this taxon to the current genus.

Heads in racemiform arrays or clustered at branch tips, forming highly branched corymbiform arrays 0.5–10 cm wide. Involucres hemispheric, 4–5 × 2.5–4 mm. Phyllaries 28–34 in 4–6 series, mostly whitish tan, midnerves mostly obscure, outer ± thickened distally, convex, ovate or oblong to spatulate, 0.5–4 × 0.8–1.2 mm, unequal, chartaceous, margins broadly scarious, entire or ± fimbriate, stipitate-glandular, apices rounded-obtuse, faces glabrous. Receptacles usually with 3–5 scales 0–1 mm. Ray florets 0. Disc florets 8–14; corollas 3.5–4.2 mm, glabrous, lobes 1.2–1.7 mm; style branches exserted, 1.7–2 mm, appendages attenuate, 0.7–0.9 mm.
