Phyllaries in 4–5 series, sparsely stipitate-glandular, margins fimbriate (midnerves pronounced), apices acute, apical hairs twisted-sericeous, faces densely stipitate-glandular. Ray-florets 11–16; laminae 9–13 mm. Disc-florets 25–40; corollas 6.5–8 mm, glabrate to sparsely short piloso-sericeous, lobes 0.5–0.8 mm, sparsely short piloso-sericeous.
