Habit | Annuals, 10–60 cm (gland-dotted; taprooted). |
Stems | erect to decumbent, much branched, sometimes arachnose in early growth. |
Leaves | basal and cauline; alternate; petiolate or sessile; blades (1-nerved) obovate to spatulate (bases clasping to subclasping), margins pinnatifid [lobed or toothed], (apices rounded to obtuse or acute) faces glabrous, villous, or tomentose, sometimes stipitate-glandular. |
Involucres | shallowly hemispheric or cupulate, ([3–]4–6 × 4–10 mm). |
Receptacles | conic, pitted, epaleate. |
Ray florets | 18–28[16–200] (in 1[–4] series, 1-nerved, midnerves barely evident), pistillate, fertile; corollas white to bluish white (laminae broad or filiform, longer or shorter than involucres). |
Disc florets | 130–300 bisexual, fertile; corollas yellow, tubular-funnelform (with slight differentiation of tubes and limbs), tubes shorter than throats, lobes 3–5, erect, deltate; style-branch appendages triangular. |
Phyllaries | 10–25 in 2–3 series, lanceolate-triangular, subequal, thinly herbaceous, flat, margins scarious or not, abaxial faces glabrous or stipitate-glandular, villous, or tomentose. |
Heads | radiate, usually borne singly (axillary, apparently opposite leaves), or in loose corymbiform arrays. |
Cypselae | oblong to narrowly obovoid, slightly compressed, 2-ribbed, glabrous or stipitate-glandular; pappi whitish, coroniform (cartilaginous crowns or shallow cups [broad, flaring]). |

Discussion | Species 6 (1 in the flora). The species of Egletes occur mostly in coastal habitats, from south Texas and Mexico through Central America, northern South America, and the Lesser Antilles. Plants are characterized by their low, herbaceous habit; glandular-resinous vestiture; narrow, multiseriate, often inconspicuous rays; conic receptacles; and compressed, glandular cypselae with coroniform pappi.
