Morphology

Rhizomatous and colonial perennial, eglandular throughout; stems 20-120 cm; basal leaves clustered, cordate, the sinus rounded, short-acuminate to obtuse, long-petiolate; middle and upper leaves gradually or abruptly reduced, becoming sessile and ovate to lanceolate or elliptic; inflorescence corybiform, puberulent, few-bracted; involucres 5-10 mm, often narrow; involucral bracts narrow, sometimes a little loose, those of the inner row longer than the rest; rays 6-14, white.

Notes

Flowers: July to October

Wetland indicator: NA

Closely resembles E. macrophylla which usually has bluish rays rather than the white rays of E. schreberi. Pale flowered forms of the former can be distinguished by its stipitate-glandular involucral bracts and lower leaf surfaces. The bracts of E. schreberi are at most only sparsely stipitate-glandular and the lower surface of its leaves are merely villous and eglandular.
