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.
