25. APHANOSTEPHUS DC. Prodr. 5: 310. 1836 
Erect or ascending canescent branching herbs, with alternate leaves, and rather large 
heads of both tubular and radiate flowers, solitary at the ends of the branches. Involucre 
hemispheric, its bracts lanceolate or linear, scarious-margined, imbricated in a few series, the 
outer smaller. Receptacle convex or conic, naked. Ray-flowers pistillate, white or purplish. 
Disk-flowers perfect, yellow, their corollas tubular, the limb expanded above, 5-dentate. 
Anthers obtuse and entire at the base. Style-branches flattened, their appendages short, 
obtuse. Achenes many-ribbed. Pappus a short dentate crown. [Greek, faint-crown.]

entire, narrowed into margined petioles; upper 
leaves lanceolate, oblong or oblanceolate, obtuse 
or acute, mostly sessile, smaller; heads 8’’-12”

26. BELLIS [Tourn.] L. Sp. Pl. 886. 1753. 
Tufted herbs, with branching or scapose stems, alternate or basal leaves, and rather large 
heads of both tubular and radiate flowers, solitary at the ends of the branches, or of the 
monocephalous scape. Involucre hemispheric or broadly campanulate, its bracts herbaceous, 
imbricated in I or 2 series, nearly equal. Receptacle convex or conic, naked. Ray-flowers 
white or pink, pistillate. Disk-flowers yellow, perfect, their corollas tubular, the limb 4-5-toothed. 
Anthers obtuse and entire at the base. Style-branches flattened, their appendages short, tri- 
angular. Achenes flattened, obovate, nerved near the margins. Pappus none, or a ring of 
minute bristles. [Latin, pretty.] 
About 9 species, natives of the northern hemisphere. Only the following are known to occur 
in the United States, but 2 others are found in Mexico. Type species: Bellis perennis L.
