Leaves alternate, thick, firm, also velvety-hairy, the lower ones spatulate, three-nerved, wavy-edged, tapering to petioles; the upper ones much smaller, acute, entire, and sessile. Panicles rather narrow and racemose, the branchlets held nearly erect, making the cluster compact and not one-sided; heads small, very bright yellow. Achenes downy-hairy, with fine, bristly pappus.
