Sigesbeckia orientalis head2 (15521153164)

Description:

Description: Native or introduced, warm season, annual, erect, shrubby herb to 80cm tall, with slightly hairy stems. Leaves are opposite, hairy and lanceolate, with toothed margins and often with prominent lobes near the base. Heads have five spreading prominent bracts covered in sticky glandular hairs. Florets are yellow, tubular and ligulate. Flowering is in spring and summer. Debate exists as to whether this is a native species. Grows on a wide range of soils. Often found in rainforests and in moist sheltered areas especially where there has been some disturbance. A minor weed that is unlikely to be eaten in quantity by stock due to its bitter taste. Little information on management. No herbicides are registered for its control, although hand pulling is likely to be effective. Used in herbal medicine. Date: 29 May 2014, 12:19.
