Description: 

Genus: "Erect or ascending herbs or shrubs; leaves opposite, the blades entire; inflorescences terminal and axillary, spicate, erect, many-flowered; becoming elongate, with only a few flowers open at the same time; flowers hermaphrodite, solitary in axils of acute, membranous, persistent bracts, subtended by 2 bracteoles, deflexed after anthesis, the bracteoles consisting of a long spine and bearing on each side of base a shorter, membranous, nerveless wing; tepals 5, spreading during anthesis, before and after anthesis erect, membranous or herbaceous, 1- or more-nerved, acute, sometimes pungent in fruit; stamens 5, much shorter than perianth, the filaments proximally connate into a short cup, the free parts alternating with short, broad pseudostaminodes, the anthers oblong, 2-celled (4-loculed); ovary glabrous, the ovule 1, pendent from a long funicle, the style filiform, short, the stigma capitate, utricle falling off together with perianth and bracteoles, ellipsoid, indehiscent, 1-seeded, with truncate or depressed apex, thin-walled, the seed erect."  (Smith, 1981; p. 290)

Species: "A coarse, ligneous herb or shrub 0.8-4 m high, sometimes almost treelike. The tepals are white to pale lavender, the filaments while to rich pink, and the fruit orange to reddish purple or brown."  (Smith, 1981; p. 290).

"A coarse, rambling or erect widely branched annual or short-lived perennial with a semi-woody base; taproot long with lateral branches throughout; stem 0.5 to 2 m tall, angularly-ribbed, generally square, more or less densely hairy and thickened above the nodes; leaves opposite, oblong-obovate to elliptic or obovate from an acute or obtuse base; tip acuminate, acute, obtuse or rounded; blade entire, flat or somewhat wavy, more or less pubescent, 2 to 10 cm long, 0.7 to 5 cm wide; petiole 0.5 to 1.5 cm long; inflorescence terminal spikes, rigid, 10 to 50 cm long excluding the peduncle, with paired branches below; rachis robust, angularly-ribbed, more or less hairy; flowers small, green, perfect, densely arranged at top of spike, less clustered in the center, scattered and often in pairs near the base; subtended by long-acuminate bracts or bracteoles, 2 to 3.5 mm long, stiff and spiny, erect before anthesis reflexed later, persistent; sepals 5, green with pale margins, ovate-lanceolate, acuminate, 3.5 to 5.5 mm long during anthesis, five filaments 2.2 to 3.5 mm long; pseudo-staminodia with or without dorsal, truncate, long-fringed scales; ovary top-shaped with 1- to 2-mm style; fruit and utricle (a small prickly bur), 2.5 to 2.8 mm long, rounded at the base; enclosed by persistent perianth and bracts, 4 to 5 mm long, detaching easily from rachis; seed 2 to 3 mm long, 1 to 1.5 mm wide, truncate above, reddish to dark brown and shiny, enclosed in chaffy calyx parts that remain attached.  This species is readily distinguished by the opposite leaves, branched stem and spiny bracts that are erect before flowering but then become reflexed and readily adhere to animals and clothing"  (Holm et al., 1997; p. 13).

Description from the Flora of China online.
Description from the Flora of North America onkline.

Habitat/ecology:  "It frequently occurs in waste areas, and along roadsides, foot paths, railroads and sand dunes.  It often infest fence rows, open woodland, and the boarders of forests and coffee fields.  It has adapted to a wide range of environments (Holm et al., 1997; p. 13).

In Fiji, "occurs from near sea level to about 900 m elevation as an abundantly naturalized weed on rocky shores, limestone islets, and grassy slopes, in coastal thickets, cultivated areas, and along roadsides and forest trails" (Smith, 1981; p. 290).  In Hawai‘i, "naturalized in low elevation, open, dry disturbed habitats, such as along roadsides"  (Wagner et al., 1999; pp. 180-181).  In Niue, "locally fairly common in waste places, especially near tracks" (Sykes, 1970; p. 40). In Guam, "a troublesome, frequent weed of waste ground, trails, etc." [probably native] (Stone, 1970; p. 270). In Papua New Guinea, "a weed of pastures, roadsides and waste places; also in natural situations, behind beaches, in savannah grassland. Widely spread, at low elevations in areas of seasonal climate" (Henty & Pritchard, 1975; p. 51).  In Tonga, "a common plantation and waste area weed" (Yuncker, 1959; p. 108).  In Papua New Guinea, "a weed of dry open places, such as roadsides and gardens, especially in areas subject to a dry season, at 0-200(?) altitude"  (Womersley, 1978; p. 15).  In Tonga, "a common plantation and waste area weed" (Yuncker, 1959; p. 108).

Propagation:  Seed

Native range:  "Probably indigenous in southeastern Asia and now a ubiquitous weed, found in Pacific archipelagoes eastward to the Tuamotus" (Smith, 1981; p. 290).

"Native or aboriginally introduced to Polynesia" (Whistler, 1988; p. 6). Fosberg et al. (1979; p. 67) lists as native to Micronesia.
