Common name(s): [more details]

Hawaiian: pualele

Tahitian: ma‘a rapiti, pualele

Habit:  herb

Description:  "Erect or ascending herbs, branched, 20 to 60 (-100) cm tall. Stems glabrous to usually sparsely pilose. Basal leaves tending to form rosettes, basal and lower cauline leaves ovate, more or less dentate, petiolate, blade usually strongly decurrent on petiole; middle cauline leaves oblong to oblong lanceolate, acute, base amplexicaul-hastate, margins shallowly to deeply dentate; upper cauline leaves and bracteat leaves ovate to lanceolate, base amplexicaul-cordate, margins strongly to weakly dentate to entire. Heads in very openly branched panicles, with 1 or few pedunculate heads on each branch; peduncle usually with a minute linear bract. Involucre cylindric to usually somewhat urceolate, ca. 15 x 5 mm; bracts ca. 10. Florets definitely exceeding involucre at anthesis; corolla brick red; corolla tube very slender, limb cylindric, lobes 10.1-1.5 mm long. Achenes ca. 5 mm long, dark brown, 5-ribbed, rib grooves white puberulous; pappus white" (Digital Flora of Taiwan).

"Vegetatively similar to E. coccinea but the leaves more coarsely dentate. Heads cylindrical, ca. twice as long as wide, ca. 3/4 as long as corolla; involucral bracts 10-13, usually 9-14 mm long; florets ca. 50 per head, conspicuously longer than the involucral bracts by often as much as 2-5 mm, corollas brick red or rarely lilac, the lobes 1.1-1.5 (-2) mm long" (Wagner et al., 1999; p. 312).

Habitat/ecology:  In Hawai‘i, "a common weed of low elevation, dry, urban and disturbed habitats" (Wagner et al., 1999; p. 312).  In Fiji, "rare from near sea level to 600 m on reed-covered hillsides or on edges of lowland forest" (Smith, 1991; p. 318).  In American Samoa, "occasional as a weed in waste places on Tutuila" (Whistler, 1988; p. 10).  In Taiwan, "locally cultivated as a garden ornamental, escaped and naturalized in waste places"  (Digital Flora of Taiwan).

Propagation:  Seed

Native range:  Perhaps Central or East Africa (Wagner et al., 1999; p. 312).  "Probably indigenous in central or eastern Africa but widely established in the New World in the latter part of the nineteenth century centering in the US and the West Indies, and subsequently from Mexico to northern South America.  It was apparently introduced into Pacific areas in the early part of the present century" (Smith, 1991; p. 318). Origin uncertain (GRIN).
