"Heterotheca grandiflora" is a species of flowering plant in the daisy family known by the common name telegraphweed. It is native to the southwestern United States and northern Mexico, but it can be found in other areas as an introduced species, such as Hawaii. It is a roadside weed even where it is native. This is a tall, bristly, glandular plant exceeding a meter in height and densely foliated in hairy to spiny toothed or lobed leaves. Leaves are smaller and more widely spaced toward the top of the stem, which is occupied by an inflorescence of bright yellow daisylike flower heads. The disc and ray florets drop away to leave a spherical head of achenes, each with a long white pappus.
