Dieteria asteroides
fall tansyaster, hoary aster
, branches, and peduncles usually hairy, puberulent, or canescent, often sparsely stipitate-glandular (glabrous or densely stipitate-glandular in var. glandulosa).
blades lanceolate to oblanceolate, mid 20–100 × (2–)6–20 mm, margins entire to irregularly serrate, faces puberulent or canescent, often sparsely short-stipitate-glandular (densely, stiffly long-stipitate-glandular in var. glandulosa);
distal bases cordate to auriculate, clasping.
broadly turbinate to hemispheric.
3.5–7 mm diam.
pistillate, fertile;
laminae white to purple, 10–20 × 0.8–1.5 mm.
5–8 mm.
in 5–12 series, spreading to reflexed, apices acute to long-acuminate, 1–6 mm, herbaceous, faces puberulent or canescent throughout (on both indurate bases and foliaceous apices), sometimes sparsely stipitate-glandular (moderately to densely stipitate-glandular in var. glandulosa).
glabrous or moderately appressed-hairy.
