Heteropappus (Greek, two kinds of pappus). Compositae. A hardy herbaceous perennial that bears azure-blue aster-like flowers in summer. Herbs, erect, branched above: lvs. alternate, entire or coarsely toothed: heads in loose irregular panicles or solitary at the tips of branches, rays white or sky- blue. The genus is closely related to Aster, having the habit of the asters of the section Calimeris. The plant in the trade is known as Calimeris talarica. Heteropappus is closely related to Boltonia and is not far from Callistephus, which contains the China asters. The chief botanical distinction resides in the pappus, which in the large group containing Callistephus and Aster is composed of numerous bristles arranged in one or more series, while Boltonia and Heteropappus belong to a group in which the pappus is anomalous. In Boltonia it is composed of very short, somewhat chaffy bristles, with the addition usually of 2-4 awns not longer than the achenc. In Heteropappus the pappus of the rays is composed of very short, somewhat chaffy bristles, while in the disk-fls. it consists of numerous slender bristles arranged in 1 or 2 series.—A genus of 2-4 species from Japan and China.
