Heads borne singly. Peduncles 3–12 cm. Involucres hemispheric, mostly 5–8 × 7–12 mm Phyllaries mostly 21–34, floccose-tomentose. Rays mostly 20–40; laminae elliptic to obovate, mostly 7–10 × 4-7 mm, apices shallowly 3-toothed. Disc florets mostly 40–50; corollas 3 mm, tubes 0.3 mm, lobes 0.25 mm; style-branch apices acute. Cypselae 3 mm. 2n = 32.
Phenology: Flowering Mar–Nov (depending on rains).
Habitat: Sandy plains and mesas
Elevation: 100–2000 m

Discussion
Baileya pleniradiata is superficially similar to B. multiradiata and autumnal forms of the latter have often been misidentified as the former (see discussion under B. multiradiata). The two species occasionally occur together or in proximity; hybrids have not been noted. Style appendages readily allow distinction between the two taxa.
Selected References
None.
