Section yellow-white, pith white, loose. leaves much shrinkage broken, were flattened after a complete oval or lanceolate, apex acuminate, base cuneate, margin crenate serrated, long 3 ~ 5cm, width I ~ 2cm, dark green or gray-green, on the surface is white pubescent, lower surface veins prominent, densely gray pubescent. capitulum top stems arranged in corymbs compound , inflorescence densely pubescent stem, petals and more, detached, and the remaining achenes involucre, mature achene black, with 5 edges, pappus white.
