Monolopia de Candolle sect. Pseudobahia A. Gray in W. H. Brewer et al., Bot. California 1: 383. 1876 (as Pseudo-Bahia)

Annuals, to 30(–70) cm. Stems erect, usually branched. Leaves cauline; mostly alternate; usually petiolate; blades usually 1–2-pinnately lobed, sometimes 3-lobed or entire, faces sparsely to moderately woolly. Heads radiate, borne singly. Involucres hemispheric, 5–9 mm diam. Phyllaries persistent, (3–)8 in 1 series (± erect in fruit, connate at bases or to 1/2 their lengths, elliptic, lanceolate, or oblanceolate, equal, margins somewhat hyaline, apices acute to acuminate, abaxial faces usually woolly). Receptacles conic to hemispheric, pitted or smooth, glabrous, epaleate. Ray florets (3–)8, pistillate, fertile; corollas yellow (with rings of hairs at bases of laminae). Disc florets 8–25+, bisexual, fertile; corollas yellow (with rings of hairs at bases of limbs), tubes shorter than funnelform or cylindric throats, lobes 5, ± deltate (anther appendages deltate, widest at bases, glandular; style-branch appendages deltate). Cypselae ± obcompressed, 3–4-angled and obpyramidal to clavate, hairy or glabrate; pappi 0, or coroniform (minute scales). x = 4.

Species 3 (3 in the flora): California.

B. G. Baldwin and B. L. Wessa (2000) found that Pseudobahia bahiifolia and P. peirsonii nest within a clade of Eriophyllum and Syntrichopappus species; circumscriptions of these genera are likely to change.
