Lorandersonia baileyi (Woot. & Standl.) Urbatsch, R. P. Roberts & Neubig

Lorandersonia baileyi is often treated as a subspecies of L. pulchella. Phylogenetic analyses (R. P. Roberts and L. E. Urbatsch 2004) indicate that the two are not sister taxa.

Shrubs, 25–70 cm. Stems single, greenish when young, becoming whitish to gray, fastigiately branched distal to middle (angled from leaf bases), glabrous or puberulent. Leaves ascending to appressed; blades linear or linear-oblong, 4–35 × 0.5–3 mm, flat or adaxially concave, margins ciliolate, midveins evident, often purplish, apices acute to acuminate, faces glabrous. Heads usually in cymiform to corymbiform arrays 0.5–7 cm wide, sometimes borne singly. Involucres obconic to cylindric, 10–15 × 4–6 mm. Phyllaries 20–25 in 4–5 series, in 5 vertical ranks, mostly tan, shiny, with green subapical patch, midnerves mostly evident on distal ¹ / 2 , keeled, ovate to oblong or lanceolate, 1–10 × 0.8–2.3 mm, unequal, mostly chartaceous, margins entire, narrowly scarious, apices acute to attenuate or acuminate, faces glabrous. Receptacles with 0–1 central awn ca. 0.5 mm. Ray florets 0. Disc florets 5; corollas 9–14 mm, glabrous, lobes 1–1.7 mm; style branches exserted, 4.1–4.6 mm, appendages narrowly triangular, 2–2.8 mm. Cypselae brownish, turbinate, 5–7 mm, sharply 4-angled, 5–8 ribbed, faces sparsely or rarely densely hairy; pappi yellowish tan, 9–12 mm. 2n = 18 [as Chrysothamnus pulchellus].

Lorandersonia baileyi (Bailey's rabbitbrush), is a North American species of flowering plants in the tribe Astereae within the family Asteraceae. It was initially discovered in the Guadalupe Mountains of New Mexico in 1902, and has since been collected in Arizona, Utah, Colorado, Kansas, Oklahoma, Texas, Chihuahua, Coahuila, and Nuevo León.

Lorandersonia baileyi is a branching shrub up to 70 cm (28 inches) tall. It has many small yellow flower heads, each with about 5 disc florets but no ray florets.
