Comments

There are collections of Solidago multiradiata from all mountain regions of the Watershed, east and west. Note that this species is not easy to separate from Solidago simplex, with minute differences in the phyllaries being the surest characteristic, and with hybridization of the two species always a possibility. In the USA, the eastern border of the distribution lies not much beyond the Watershed. The species follows the Rio Grande drainage south only as far as Santa Fe Co, New Mexico.
