Description:  "A subshrub 0.6 to 3 m in height and up to 7 cm in basal diameter. The species usually has a single stem emerging from the ground but normally produces several stems or major branches low on the stem and many branches throughout. The nearly smooth bark is tough and fibrous, brown on the outside and green within. Its pale yellow wood is of medium density. Plants are supported by a tap and lateral root system of tan or ivory-colored, tough and flexible roots. Grayish green, discolorous, alternate leaves are stellate-pubescent both above and below, ovate, angulate or shallowly lobbed, 1 to 12 by 1 to 12 cm, and have serrate margins. Axillary flowers are usually solitary and have five pink petals. The flowers are about 1 cm broad. The fruits are 8- to 10-mm globose capsules that break into five fine-barbed (glochidate) mericarps. (Howard 1989, Liogier 1994, Stevens and others 2001)"  (Wildland shrubs of the United States and its territories).

"Erect subshrub to 1 1 m tall; leaves palmately lobed or angled, downy grayish pubescent with stellate hairs, 4-8 cm long, usually 5-lobed with the lobes again pinnatifid, or sometimes subentire but angled; flowers clustered; corolla pinkish-violet, about 1 cm broad; fruit pubescent and beset with hooked bristles (glochidia)" (Stone, 1970; pp. 417-418).

Some botanists recognize U. sinuata as a separate species or a variety. It is distinguished from U. lobata by having, among other characters, deeply lobed leaves in which the sinuses are rounded rather than acute (Wagner et al., 1999; p. 903).

Habitat/ecology:  "Readily invades disturbed areas, especially poorly managed pastures, scarified and eroded areas, and perennial crop plantations but is much less of a problem in annual crops. The species does not compete well in tallgrass swards and brushlands and does not grow under forest canopies. Ceasar weed grows on a wide variety of soils of varying fertility derived from most parent materials. It tolerates salt spray and a moderate amount of salt in the soil but does not grow in saturated soils. In Puerto Rico, it occurs in areas that receive from about 1400 to 3000 mm of mean annual precipitation, forming thickets in favorable sites"  (Wildland shrubs of the United States and its territories).

Invades disturbed areas.  In New Guinea, "a weed of waste land, roadsides and pastures. Mostly at low altitudes, but occurring to 1500 m" (Henty & Pritchard, 1975; p. 124).  In Hawai‘i, "naturalized in low elevation disturbed areas, 20-30 m" (Wagner et al., 1999; p. 903). In Fiji, "found at elevations from near sea level to the summit of Mt. Tomanivi, 1,323 m.  It is a pernicious weed abundantly naturalized in gardens, canefields, pastures, clearings, and grassland, and also found along forest trails and on open hillsides"  (Smith, 1981; pp. 431-432). In Tonga, "frequent as a roadside and waste-area weed" (Yuncker, 1959; pp. 182-183). In New Caledonia, "espèce sinon indigène, d'introduction ancienne aux îles du Pacifique Sud" (MacKee, 1994; p. 99).

Propagation:  Seed. Barbs on seed cling to fur and clothing.

Native range:  "Pantropical, but probably of Asiatic origin and spread into many parts of the world by aboriginal voyagers; it was doubtless brought into many Pacific areas in this manner"  (Smith, 1981; pp. 431-432).
