Symphyotrichum chilense

Symphyotrichum chilensis (Nees) G. L. Nesom is native to along the Pacific coast from Vancouver Island south to southern California in grasslands and marshy areas. The species has long-rhizomes and The outer phyllaries are obtuse (usually shorter than inner); fruits 3.5–4.5m. The outer phyllaries of S. subspicatum are usually acute and often nearly as long as the inner phyllaries. The species includes 2n=48 and 2n=64 individuals and rarely 2n=96.

The species was erroneously thought by Nees to occur in Chile. The plants named Aster chilensis var. medius Jepson are hybrids of S. chilense and S. lentum.
