Solidago chilensis

Solidago chilensis Meyen (including S. linearifolia, S. patagonica) is native to South America from Bolivia south to much of Argentina.  The stems vary from having the short dense hairs of the Tortifolia Group to being glabrous.  The inflorescence is elongated and secund pyramidal like that of S. juliae, S. pringlei, and S. leavenworthii, its likely closest relatives in North America.  It is closely related to S. microglossa of South America, but has shorter and often much less dense hairs. Solidago chilensis is diploid 2n=18.

The species has been introduced into Brazil, the West Indies, and Madeira Is. of the coast of Africa (Conçalves Silva et al. 2009).  These plants are usually the glabrous-stem morph.
