Names
CUSCUTA campestris Yunck. [family CONVOLVULACEAE], (1932).
Information
Stems up to 1.2 mm in diam., orange, smooth or tuberculate. Inflorescences branched and compact, generally 2–5-flowered. Flowers (4–)5-merous, 1.6–3 mm long, sessile or on up to 3 mm long pedicel. Calyx cup-shaped, ± as long as the corolla-tube, smooth, whitish or pellucid; lobes 0.7–1.3 x 0.8–1.7 mm, broadly ovate, blunt, overlapping at the base, erect; tube up to 0.8 mm long. Corolla urn-shaped, smooth, whitish or pellucid, persistent in fruit; lobes 0.9–1.5 x 0.8–1.3 mm, ovate-triangular or triangular, mucronate, smooth or somewhat papillate at the tip; tube up to 1.5 mm long; scales up to 1.9 mm long, well developed and longer than the corolla tube, with numerous club-shaped processes. Stamens 0.8–1.2 mm long; anthers 0.4–0.6 mm long, ovoid, yellowish or greenish; filaments 0.4–0.7 mm long, subulate. Styles 0.5–1 mm long, unequal, terete; stigmas approximately 0.3 mm in diam., subglobose, orange or greenish. Fruit a subglobose capsule up to 4.2 mm in diam., indehiscent. Seeds subglobose or ovoid, up to 1.7 mm long.
Range
S2 native in southern USA, naturalised throughout the world and an economically important parasitic weed.
Distribution
SOMALIA Hedberg & Warfa 71.
Notes
First record for Somalia. This species belongs to C. subgenus Grammica, characterized by free styles and globose or capitate stigmas. Other species of this subgenus are known from adjacent countries and could be found also in Somalia. C. kilimanjari Oliv., with globose flowers about 5 mm wide, thin and scarcely developed corolla-scales, and dehiscent fruit, was cited in Cuf. Enum.: 728 (1961) from northern Somalia, but no specimens have been seen. C. hyalina Roth differs by the acute calyx- and corolla-lobes and absence of corolla-scales. C. australis R. Br. has indehiscent fruits but the corolla-lobes are obtuse and the corolla-scales are thin and shorter than the corolla-tube.
