Striga chrysantha is a plant type from the genus Striga in the family of broomrape plants (Orobanchaceae).
description
Striga chrysantha is a tufted, parasitic , annual plant that grows to a maximum of 12 cm high . It is scaly and densely hairy, the stem is indistinctly rectangular. The leaves are smaller than 10 × 2 (rarely up to 3) mm, lanceolate and scale-like. The leaf margin is entire, the veins are indistinct, the leaves are shorter than the internodes .
The flowers are relatively dense and alternate in spike-shaped inflorescences , these inflorescences are about as long as the vegetative shoot. The flowers are accompanied by two bracts . These are 6 × 2 mm in size, lanceolate and shorter than the chalice . The bracts of the entire inflorescence are similar.
The calyx is ten-ribbed and 8 to 15 mm long. The calyx tube has a length of 6 to 13 mm and is covered with five almost identically shaped, triangular, 2 mm long calyx tips. The calyx lobes are thus significantly shorter than the calyx tube. The crown is glowing yellow. The corolla-tube is slender, 20 to 25 mm long, curved, widened above the calyx and hairy glandular. The lobes of the lower lip have a size of 15 × 8 mm, they are protruding and broadly rounded. The upper lip has a size of 8 × 10 mm, is bent back and notched.
Occurrence
The species is only known from the south of the Central African Republic and the north of the DR Congo .
