Description:  "Erect, woody herb or shrub 75-150 cm in height.  Stems glabrous, longitudinally grooved.  Leaves simple, alternate; blade ovate to rhomboid in shape with 3-5 lobes, sometimes nearly as wide as broad, and 2-10 cm long.  Leaf margins irregularly serrate, leaf surfaces softly-pubescent with stellate hairs, blade palmately veined.  Flowers in short, condensed, axillary cymes.  Calyx divided into five pubescent, narrowly oblong sepals; corolla of five yellow, obovate petals about 5 mm long.  Stamens 10-15.  Fruit a subglobose bur with the body 3-4 mm in diameter, covered with 75-100 hooked spines 1.0 to 1.5 mm long" (Whistler, 1983; p. 69).

"An erect shrub to 1.5 m tall; leaves ovate-oblong, 3-lobed; serrate; flowers small yellow axillary clustered; fruits with scattered reflexed hairs on the hooked spines" (Stone, 1970; p. 406).

Habitat/ecology:  "Invades pastures, disturbed areas in forests.  Prevents establishment of native species.  Burs a nuisance to man and beast in pastures and forests"  (Motooka et al., 2003).  In Hawai‘i, "naturalized in dry, disturbed sites and pastures, 5-760 m"  (Wagner et al., 1999; pp. 1292, 1294).  In Niue, "a nuisance in the plantations.  It is also frequently seen in waste places, along tracks, and in similar disturbed sites"  (Sykes, 1970; p. 206).  In Fiji, "found from near sea level to an elevation of 600 m as an abundant weed along roads and trails, in clearings, waste places, thickets, and canefields, and on open hillsides"  (Smith, 1981; pp. 378-379). In New Guinea, "a plant of regrowth and savannahs, and a weed of roadsides and pastures. At low altitudes" (Henty & Pritchard, 1975; p. 155). In Tonga, "frequent as a plantation and waste-area weed" (Yuncker, 1959; p. 180). In New Caledonia, "mauvaise herbe très commune" (MacKee, 1994; p. 135). "Cette mauvaise herbe pantropicale se rencontre près de tous les lieux habitésl, dans les terrains vagues, les cultures, le long des chemins, dans les zones défrichées ou reboisées, de 0 à 600 m d'altitude" (Tirel, 1996; pp. 129-131).

Propagation:  Burs that stick to clothing and fur.

Native range:  Probably tropical America, now pan-tropical weed.

Comments:  On State of Hawai‘i noxious species list.

Control: 

Physical:  "Burs stick to clothing and fur, so sanitation measures and control before seeding are critical to prevent spread of bur bush"  (Motooka et al., 2003).

Chemical: "Sensitive to foliar drizzle applications of dicamba, picloram, and probably triclopyr"  (Motooka et al., 2003).

Additional information:  Information from the book "Weeds of Hawaii‘s Pastures and Natural Areas; An Identification and Management Guide" (Motooka et al., 2003). (PDF format).

Additional online information about Triumfetta rhomboidea is available from the Hawaiian Ecosystems at Risk project (HEAR).
