Annual herb, 30-60 cm, often branched. Stem and branches hispid, with spreading hairs. Leaves membranaceous, linear-lanceolate, or narrowly lanceolate, 4-6 by 0.8-1 cm, acuminate, base attenuate, margin remotely crenate, tomentose on both surfaces, pilose on nerves; petiole 0.5-1 cm long, densely hispid. Flowers subsessile, in terminal verticillasters, forming a globular head 1.5-2.5 cm Ø. Bracts narrowly lanceolate, 8-10 mm long, ciliate along the margins. Calyx 7-10 mm (only slightly accrescent in fruit), cylindric, tube pilose, 10-nerved and 10-toothed, mouth strongly oblique, teeth erect, the posterior one longest. Corolla 15-16 mm long, strongly curved, with a hairy ring inside near the middle; upper lip 2 mm long, densely velutinous, lower lip 6 mm sparsely pubescent. Anthers red.

Herbs annual, 20-40 cm tall. Stems hispid. Petiole short to obsolete, densely hispid; leaf blade linear or oblong-linear, 2.5-6 × 0.8-1.5 cm, strigose especially on veins abaxially, base cuneate-decurrent, margin sparsely crenate or sometimes subentire, apex obtuse, lateral veins ca. 3 pairs. Verticillasters globose, 2-2.5(-3) cm in diam., many flowered, densely hispid; bracts linear, as long as calyx, margin hispid ciliate, apex slightly spinescent. Calyx tubular, ca. 1 cm, slightly constricted at apex, slightly hispid or subglabrous at base, otherwise densely hispid outside; mouth oblique, erect; teeth straight, broadly triangular, apex spinescent. Corolla white, slightly longer than calyx tube, ca. 1.2 cm; tube ca. 8 mm; lower lip spreading, middle lobe largest. Nutlets brown, oblong, triquetrous, ca. 2 mm, shiny. Fl. and fr. year round.
An erect herb. It grows 20-50 cm high. It re-grows each year from seed. The upper stems are 4-angled. The leaves are produced opposite each other. They have shallow wide teeth around the edge. The leaves are up to 7 cm long. They have short leaf stalks. The lower leaves are lobed and larger than higher leaves. The flowers occur in dense clusters at the tips of the plant. The flower heads are white. The fruit is 4 nutlets which are brown, smooth and about 2 mm long.

Environment

Various habitats, mostly grassy plains, maize fields, open dry sandy soils, waste places, teak-forest, railway embankments, dunes, locally often common, from sea-level to c. 500 m. Fl. Jan.-Dec.It is curious to note that whereas in Java it is preferring the distinctly seasonal areas, growing in profusion in the very driest areas, it is also found in Penang and NE. Celebes with an everwet climate.
