Solidago ouachitensis
|
Solidago ouachitensis has only been collected four times since it was first collected by G. W. Stevens in 1913. During cooler, moister times this goldenrod species was likely more widespread, but is now restricted to a narrow range within the Ouachita Mountains and is thought to be a relict of the last ice age.
This goldenrod is a perennial herb that grows from two to four feet tall, producing yellow flower heads with one ray flower during the months of September and October. The Ouachita goldenrod has leaves with no stalk, the midstem leaves being coarsely toothed and larger than the few basal leaves. (USFS 2002; USFWS 1992)

State Range
Habitat
| |
Moist, well-drained, gravelly soils in shaded, north-facing slopes that are significantly cooler during the hot summer weather than less shaded areas. (Taylor & Taylor 1986)
Canopy associates include: Magnolia tripetala, Fagus grandifolia, Acer rubrum, and Quercus rubra. Ground associates include: Aesculus glabra, Asarum canadense, Campanula americana, Panax quinquefolium, Toxicodendron radicans, and Hybanthus concolor. |
Distribution

S. ouachitensis occurs in the Ouachita Mountains of Arkansas and Oklahoma. The goldenrod can be found in Polk and Montgomery counties in Arkansas, and in LeFlore county in Oklahoma. (Taylor & Taylor 1986) |
Number Left

Occurs within two counties in Arkansas, a very small number of plants occur in Oklahoma. (Taylor & Taylor 1986) |

Threats
| |
Because this species is already found in a very narrow habitat range, anything that decreases the size of its suitable habitat could threatened its continued survival. This could include loss of habitat due to development as well as global warming. |
