Leaves: Scattered, sparsely glandular, thinly linear to filiform blades, 0.5-1 mm wide and 2-5.5 cm long. Flowers: Heads solitary at ends of branches on peduncles 1-3 cm long and slightly dilated upward, involucres cylindro-campanulate, 8-14 mm high, phyllaries 5, oblong to linear; florets 12-30, corollas whitish to purplish, 6-9 mm, with darker purple streaks, tube shorter than narrow throat.
