Annual or perennial strong-scented herbs. Leaves alternate, usually more or less dis- 
sected. Heads solitary on terminal or axillary peduncles, apparently discoid. Involucres 
rotate or saucer-shaped; bracts subequal in 1-3 series. Receptacle flat or convex, papillose. 
Marginal flowers (functionally ray-flowers) pistillate and fertile, without corolla, distinctly 
pedicelled; style with persistent base; branches oblong, obtuse. Disk-flowers hermaphrodite 
and usually fertile; corollas yellow, tubular, with a short campanulate throat; lobes 4, mostly 
obtuse. Anthers with ovate tips. Style included; branches with truncate, fimbriate tips. 
Achenes obcompressed, margined or winged, those of the marginal achenes much broader. 
Pappus wanting. 
Type species, Cotula coronopifolia L.

long; leaves glabrous, somewhat succulent, 4—7 cm. long, lanceolate or broadly linear, laciniate- 
pinnatifid or toothed, or the upper entire, with the broad base sheathing or clasping; heads 
solitary at the ends of the branches; peduncles 1-5 cm. long; involucre rotate, 8-12 mm. 
broad; bracts in 3 subequal series, oblong-lanceolate to elliptic, obtuse; pistillate marginal 
flowers in a single series, on a winged stalk in fruit 1 mm. long; corollas wanting; disk-flowers 
short-stalked; corollas yellow, tubular, 1.5 mm. long, glandular-granuliferous, with 4 short 
lobes; marginal achenes with broad wings, oval in outline, emarginate at each end, glandular- 
hispidulous on the faces; disk-achenes oblong with narrower margins, 1 mm. long. 
Type Locarity: Africa. 
DISTRIBUTION: Perfectly naturalized from British Columbia to Lower California; also adventive
