Leaves basal and cauline, margins serrate, scabrous, apices usually acute, sometimes acuminate, mucronate, faces scabrous, abaxial sparsely villous to strigose with hirsute veins, adaxial strigose; basal and proximal long-petiolate (to 120 mm), petioles not winged (or rarely so), hirsute and ciliate, blades widely ovate to ovate or lanceolate, 80–190 × 50–110 mm, bases usually cordate, subcordate, or rounded, sometimes cuneate; cauline short-petiolate (to 50 mm) to subpetiolate or sessile (arrays), petioles gradually winged distally, blades ovate to lance-ovate, 20–60 × 8–30 mm, reduced distally, bases rounded to cuneate. Heads 4–80 in flat-topped, corymbiform arrays. Peduncles 0.4–1.6 cm, villous; bracts single or a second midway. Involucres cylindro-campanulate, 10–13 mm, equaling or longer than pappi. Phyllaries 36–50 in 4–5 series, ovate, elliptic, or lanceolate to linear (outer 3 × 1.5 mm, inner 13 × 0.7 mm), strongly unequal, bases indurate, green zones ± lanceolate to linear along midnerves (inner), 1 / 4 – 3 / 4 width, subapical (rarely outer foliaceous), margins hyaline, erose, ciliate, apices squarrose, acute to long-acuminate (inner hyaline), abaxial faces ± villosulous, adaxial glabrous. Ray florets 7–15; corollas whitish to cream-colored, becoming purple, 15–20 × 1–2 mm. Disc florets 20–25; corollas yellow, slightly ampliate, 6.5–8.5 mm, tubes longer than funnelform throats, lobes ± reflexed, lanceolate, 1–1.2 mm. Cypselae brown, fusiform, ± compressed, 3–4 mm, ribs 7–9, tan, prominent, crowded, faces strigillose; pappi of cinnamon (sometimes ± clavate) bristles, ± equaling disc corollas. 2n = 54.

Eurybia jonesiae

provided by wikipedia EN

Eurybia jonesiae, commonly known as Jones's aster or Almut's wood aster, is a North American species of herbaceous perennial native to the Southeastern United States, primarily in the state of Georgia with a few populations in eastern Alabama. It is found mostly in the Piedmont Region in rich oak-hickory-pine forest. Within these rich woods, it has an affinity for moist soils with habitats that include ravines, rocky ridges, and wooded slopes in the vicinity of rivers and streams. Due to its restricted range it is considered threatened by the Nature Conservancy. It has often been misidentified as Eurybia spectabilis and was declared a separate species quite recently in 1988.[3] The flowers emerge in the late summer and persist into the fall bearing cream-coloured ray florets that become purple and yellow disc florets.

Distribution and habitat

Eurybia jonesiae grows only in the Piedmont Region south of the Appalachian Mountains. In this relatively small area, ranging from 100 to 400 metres (330–1330 feet) above sea level, it is found in rich oak-hickory-pine forests in moist soils. It is most common along the wooded slopes of rivers or streams, in moist ravines and on rocky ridges.[4]
