[Overview]
A biennial 0.6–1.5 m tall, found on sunny rocky places and cliffs in the mountains of northern Kyushu.
It is usually hairless throughout.
The stem branches well.
There are basal leaves and stem leaves; the basal leaves and the lower leaves of the stem have withered by flowering time.
The stem leaves are simple and alternate, narrowly lanceolate to spatulate-linear, 5–7.5 cm long, entire, somewhat thick, with the base gradually narrowing.
Flower heads are borne at the branch tips; they are 3–4 cm across, with pale purple ray florets and yellow tubular florets.
The involucre is dish-shaped, and the involucral bracts are in 2 rows.
The achene is a flattened obovate shape 2.5–3 mm long; the pappus of the tubular florets is about 3–4 mm long and tinged reddish brown, while the pappus of the ray florets is about 0.5 mm long and white.
