Habit | Perennials (weak or monocarpic), (30–)60–110 cm; taprooted (new rosettes from bases of previous season’s stems or as side branches of primary unbolted rosettes). | Perennials or subshrubs, 30–70 cm; fibrous-rooted or rhizomatous (new rosettes from bases of old shoots, additional rosettes at ends of short lateral rhizomes or roots). |
Stems | 1–8(–20), usually ascending to erect, moderately spreading near base, rarely decumbent, frequently branched (densely leafy), sparsely lanate, stipitate-glandular distally. |
erect or ascending, sometimes branched, densely short-woolly. |
Leaves | basal blades usually spatulate to oblanceolate, rarely obovate, (35–)55–120(–150) × 15–20(–30) mm, bases narrowly attenuate-cuneate, margins entire or apically serrate-denticulate, faces loosely long-lanate, obscurely stipitate-glandular, viscid; cauline sessile, blades usually oblong to oblong-elliptic, sometimes ovate to lanceolate, bases usually slightly auriculate-clasping, truncate to rounded, margins undulate, some cilia 2–3 mm, faces moderately woolly-lanulate, stipitate-glandular; mid to distal leaves ascending, often appressed, apices usually obtuse, sometimes subacute, mucronate or mucronulate, faces stipitate-glandular, distalmost glabrate to sparsely woolly-pilose, densely stipitae-glandular. |
basal blades spatulate to oblanceolate, 40–100 × 15–25 mm, margins entire or apically dentate, faces densely short-woolly; cauline blades obovate to oblanceolate, gradually or hardly reduced distally, bases cuneate to slightly auriculate-clasping, margins entire, sometimes undulate, cilia rarely more than 1 mm, apices mucronulate, faces densely appressed-tomentose, sparsely stipitate-glandular (glands hidden by hair). |
Peduncles | 1–4 cm, densely stipitate-glandular; bracteoles 0–4, lineaer to oblanceolate, proximally woolly, stipitate-glandular distally. |

Involucres | (yellow-green in bud) cylindro-campanulate, 6–8.5 mm. |
(yellow-green in bud) campanulate, 5–8 mm. |
Ray florets | 16–22; laminae 8–9.5 × 1–2 mm. |
15–20; laminae 6–8 × 1.5–2.5 mm. |
Disc florets | 20–40; corollas 4.5–5.5 mm, lobes 0.6–1 mm. |
25–35; corollas 6–7 mm, lobes 0.5 mm. |
Phyllaries | in 5–6 series, erect, linear-lanceolate, unequal, 0.7–1.1 mm wide, apices usually acute-acuminate, sometimes acute-aristate, sometimes inner obtuse to rounded, densely stipitate-glandular, viscid. |
in 3–4 series, erect, linear, unequal, 0.6–1 mm wide, apices sharply acute or acuminate to aristate, faces stipitate-glandular. |
Heads | 10–50, in compact corymbiform to paniculiform arrays (height usually less than 1/5 plants, branches slender, ascending, stipitate-glandular, sweet camphor smelling). |
1–25+ in subumbelliform to paniculiform arrays (proximal branches sometimes also flowering). |
Cypselae | 2–2.7 mm, without ridges, shallowly ribbed or smooth, moderately long-strigose; pappi in 3–4 series, outer of linear scales 0.5–1.5 mm, inner of 30–35 bristles 5–6 mm, inner moderately clavate. |
2–2.5 mm, without ridges, smooth or faintly ribbed, moderately strigose; pappi in 3 series, outer of linear scales 0.5–1 mm, inner of 25–30 bristles 5–6 mm, inner weakly clavate. |

Discussion | Of conservation concern. Chrysopsis highlandsensis is known from Highlands, southern Polk, and northern Glades counties. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Of conservation concern. Chrysopsis floridana is found in Hardee, Hillsborough, Manatee, and Pinellas counties. It has been subject to habitat destruction at most historic sites. It is listed as endangered in the Federal Register and is in the Center for Plant Conservation’s National Collection of Endangered Plants.
