Description:  "An erect, glabrous, perennial sometimes annual herb; 30 to 120 cm tall, with a milky sap throughout; stems smooth, round, dull green or suffused with dull red; leaves simple, opposite, shortly petioled, lanceolate to oblong-lanceolate, acuminate; 7 to 13 cm long and 6 to 25 mm wide; the base narrowed; inflorescence an umbel with 6 to 15 flowers on terminal or axillary peduncles; flowers perfect, radial symmetry or irregularly shaped, bright red or orange with yellow centers; sepals 5, deeply divided, reflexed, green; petals 5, linear, base united into a fused corolla; corolla lobes red, reflexed, oblong, shaped with inwardly curved horns; stamens 5, anthers with two pollen sacs; pollen aggregates into masses called pollinia or pollen sacs; style filaments united; pistil 20carpelled; fruit a pair of dry, dehiscent, spindle-shaped follicles, 5 to 15 cm long, many-seeded, splitting lengthwise on one side at maturity; seeds ovate, flat, winged, 4 to 6 mm long, 2.2 to 4 mm wide, brown, minutely ridged, with a pappus of fine, white silky hairs at apex, 2 to 3 cm long.  This species is unique in having reflexed corolla lobes and the corona and style filaments united on top to form a broad stigma.  The milky sap in all parts and the opposite leaves also help identify the plant"  (Holm et al., 1997; p. 82).

"Erect branched herb to 1.5 m tall; leaves opposite, oblong-lanceolate, acute at both ends, 6-15 cm long, 1-3 cm wide; cymes on peduncles 3-6 cm long, 4-15-flowered; flowers bright red-and-yellow; calyx-lobes to 4 mm long; corolla to 9 mm long; corona-scales to 4 mm long; stamen-tube to 3 mm long; follicles ovoid-oblong, 5-7.5 cm long; seeds 6-7 mm long, with silky-white tuft of hairs 2-2.7 cm long"  (Stone, 1970; p. 487).

"Herbacée dressée pérenne de 50 cm à 1,5 m de hauteur, à base ligneuse, reconnaissable à ses inflorescences de fleurs orangées et rouges, ses follicules dressés contenant des graines munies d’un pappus plumeux et disséminées par le vent sur de grandes distances" (Meyer, 2008; p. 21).

Habitat/ecology:  "Occurs most frequently in pastures, wastelands and along roadsides.  It grows from sea level to over 1500 m in its region of origin.  It prefers open, sunny environments and is found on a wide range of soils" (Holm et al., 1997; p. 82).

In Hawai‘i, "naturalized in low elevation, often dry habitats" (Wagner et al, 1999; p. 240).  In Fiji, "seen as a coarse herb to 1.5 m high from near sea level to about 900 m, locally frequent along roadsides, in open fields, and in coconut plantations" (Smith, 1988; pp. 109-110).  "Occasional as a weed, particularly in pastures" (Whistler, 1988; p. 7). Moist uplands in the Galápagos Islands (McMullen, 1999; p. 258). In New Guinea, "a weed of roadsides, waste land and pastures, also in grassland, particularly in savannahs. From low altitudes to 1500 m; most often in areas of seasonal climate" (Henty & Pritchard, 1975; p. 59). In Tonga, "a common waste-area weed" (Yuncker, 1959; pp. 222-223). In New Caledonia, "elle est maintenant largement dispersée sans jamais être abondante" (MacKee, 1994; pp. 19-20); "échappé des jardins depuis 6-7 ans et intestant depuis lors à de grandes distances de Nouméa les terres argileuses humides" (Balansa 238, 1868); "vulgaire dans toute l'Ile" (de Pompéry s.n., 1880).

Propagation:  Plumed seeds that float in the wind (Whistler, 1983; p. 20).

Native range:  Tropical America, widely naturalized in the tropics (Smith, 1988; pp. 109-110).
