Description:  "Annual or perennial herbs, often somewhat woody at base; stems decumbent, sometimes ascending, or occasionally subscandent, usually 3-10 dm long, densely soft short-villous, becoming glabrate.  Leaves broadly ovate to rhombic-ovate or occasionally ovate-deltate, 1-6 cm long, 1-3 cm wide, upper surface sparsely scabrid to glabrous, lower surface sparsely puberulent to glabrate, margins crenate-serrate, apex acute to obtuse, base broadly cuneate or occasionally truncate, petioles 0.7-1.5 cm long.  Flowers 2-6 in diffuse racemose inflorescences, bracts ovate, 1.5-2.5 mm long, apex acuminate; calyx 2-3 mm long, only slightly cleft, moderately glandular pubescent, upper lip truncate or obscurely 3-toothed, lower lip 2-toothed; corolla blue, tube ca. 2.5 mm long, upper lip concave, ca. 1.5 mm long; stamens scarcely exserted beyond or included in corolla tube.  One nutlet developing, narrowly obovoid, ca. 1.5 mm long" (Wagner et al., 1999; pp. 829-831).

Habitat/ecology:  In Hawai‘i, "naturalized in low elevation, dry to wet, disturbed habitats, 1-1,000 m" (Wagner et al., 1999; pp. 829-831).  In Niue, "abundant in plantations and waste places over most of the island.  It has a spreading habit and as the plant ages the large freely branching panicles become intertwined, the result often being a densely tangled mass which covers many old plantations"  (Sykes, 1970; p. 105).  "Occasional in disturbed places in Tonga and Niue, collected only once in Samoa" (Whistler, 1988; p. 21). In Tonga, "occasional as a plantation and waste-area weed" (Yuncker, 1959; pp. 234-235). In New Caledonia, "mauvaise herbe répandue et parfois abondante, notamment aux îles Loyauté" (MacKee, 1994; p. 70).
