Maryland Goldenaster

Chrysopsia mariana is present in the Coastal Plain, Piedmont, Appalachian Plateaus, Valley and Ridge, and Blue Ridge regions. All four ploidy levels occur in partially overlapping areas in Florida, but only the hexaploid occurs in other states (J. C. Semple and C. C. Chinnappa 1986). Larger involucres occur in plants with higher ploidy levels.

Biennials or short-lived perennials, 20–90 cm; fibrous-rooted or with short lateral rhizomes (new rosettes borne on fibrous roots or at ends of short lateral rhizomes or roots). Stems erect or ascending (often purplish), usually simple, sparsely to densely silky-sericeous (hairs sometimes long, twisting together at ends). Leaves: basal blades spatulate to oblanceolate, 15–250 × 4–40 mm, bases attenuate, margins obscurely dentate apically or entire, apices acute to obtuse, faces long-sericeous, glabrescent; cauline sessile, blades lanceolate to elliptic-oblong, 10–30 mm, reduced distally, margins entire or obscurely dentate, ciliate, apices acute, faces long-silky-sericeous or glabrate. Heads 1–50, usually in crowded subumbelliform arrays. Peduncles (from axils of distalmost cauline leaves or bracteoles) 0.5–5 cm, densely stipitate-glandular (glands yellow to brown); bracteoles 0–3, linear, stipitate-glandular. Involucres campanulate, 7–10 mm. Phyllaries in 4–5 series, erect, linear, unequal, 0.8–1.4 mm wide, apices acute, abaxial faces densely stipitate-glandular. Ray florets 10–22; laminae 8–11 × 2–3 mm. Disc florets 25–40; corollas 5–7 mm, lobes 0.5 mm. Cypselae (stramineous to purple) 2–3 mm, without ridges, shallowly ribbed or smooth, faces sparsely short-strigose; pappi in 2–3 series: outer of bristles 0.5–1 mm, inner of weakly to moderately clavate bristles 4–6 mm. 2n = 8, 16, 24, 32.

Chrysopsis mariana, known as the Maryland golden-aster, is a North American species of plants in the family Asteraceae. The Maryland golden-aster ranges from Rhode Island and New York, west to Kentucky and southern Ohio, and south as far as Florida and Texas.
