Shrubs, 50–150 cm. Stems ascending to erect, much branched. Leaves mostly cauline; alternate or opposite; petiolate or sessile; blades usually 3-nerved (from at or near bases), deltate, deltate-ovate, lanceolate, lanceovate, or ovate, margins entire or toothed to laciniate, faces hispid, sericeous, or strigillose, often resinous or glanddotted. Heads radiate, borne singly or (3–25+) in ± thyrsiform arrays. Involucres campulate to hemispheric, (9–14 ×) 4–7 mm. Phyllaries persistent, 16–28 in 2–3 series (unequal, bases ovate to lanceovate, indurate, apices abruptly narrowed, herbaceous). Receptacles convex, paleate (paleae tan, conduplicate, apices acute). Ray-florets 8–15, neuter; corollas yellow (2–3-lobed). Disc-florets 40–50+, bisexual, fertile; corollas yellow, tubes shorter than campanulate throats, lobes 5, triangular (style-branches relatively slender, apices acute). Cypselae (brown to black) ± compressed, ± 3- or 4- angled, often obpyramidal, ± strigose; pappi persistent, of 2 (–6) lacerate, aristate scales (1–2.8 mm) plus (0–) 2–6 lacerate scales (0.2–1 mm). x = 18.

Distribution

sw United States, nw Mexico

Discussion

Species 12 (3 in the flora).

Although traditionally included within Viguiera, the species of Bahiopsis differ by their distinctive base chromosome number and form a basally diverging clade in subtribe Helianthinae, based on molecular data. Morphologically, they are most similar to Calanticaria, another segregate of Viguiera that is Mexican in geographic distribution, from which they differ by their branched capitulescences and having phyllaries in which the apical herbaceous portions are longer.
