Paleae yellowish (often red-tipped), apices obtuse, erose. Ray-florets 0 or 5–8; corollas yellow, laminae suborbiculate to ovate, 0–6 (–9) mm.

Discussion

A. M. Torres (1963) speculated that Zinnia anomala, which often lacks rays or has inconspicuous rays, might be an octoploid derivative of the rather similar Z. grandiflora, which has showy yellow rays.
