description
Striga elegans is a 30 (rarely up to 50) cm high, parasitic , annual plant . It grows rigidly upright, is unbranched or branched from the base into two to three branches, scaly and hairy with dense stiff hair. The stem is indistinctly rectangular and furrowed. The leaves have a size of 10 to 20 (rarely up to 30) × 2 to 3 mm, they are linear or lanceolate in shape, the edge is entire, the veining is indistinct. They stand opposite and are shorter than the internodes .
The flowers are opposite in dense grape-like inflorescences , these are shorter than the vegetative shoot. The flowers are accompanied by two bracts , these are 3 to 12 × 1 to 2 mm in size, lanceolate and shorter than the calyx .
The calyx is ten to fifteen ribs and 8 to 13 mm long. The calyx tube has a length of 6 to 7 (rarely up to 9) mm. It is covered with five equally shaped or six unevenly shaped, linear to lanceolate shaped and 2 to 5 mm long lobes, which are thus shorter than the calyx tube. The crown is bright scarlet with a yellow throat. The corolla-tube is 14 to 18 mm long, curved, widened above the calyx and densely hairy glandular. The lobes of the lower lip are 5 to 10 × 3 to 5 (rarely up to 7) mm in size and are ovoid. The upper lip is 3 to 5 × 6 to 11 mm in size and notched.
