Discussion
A velvety-tomentose herb sometimes used in herbal medicines, Sida cordifolia is believed to have originated in India, but has been widely spread in warmer regions globally. In many areas it is considered to be an invasive weed. There is considerable variation in the flower color patterns; the velvety-tomentose indument and retrorsely barbed, relatively large or conspicuous spines can help in identification.
