Abstract

Sweet broomweed (Scoparia dulcis L., Scrophulariaceae) is a perennial herb widely distributed in the torrid zone. The original habitat of this plant is tropical America. Stems are erect, branching, and sometimes woody at the base, 25–80 cm tall. (Fig. 1) Roots are pale yellow and straight, 10–15 cm long, with many lateral roots. Leaves are lanceolate, elliptical, or obovate, 5–20 mm long, with serrations at the edge, and are opposite or verticillate. The plant has small, white flowers with four calices. The corrola is actinomorphic and split in four. Flowers are 4–5 mm in diameter and bear four stamens and a pistil. Flowering time is summer and autumn. After flowering, ovate or globular capsules mature (2–3 mm in diameter), which contain many powder-like seeds.
