Thalictrum coriaceum (Britton) Small. Section: Heterogamia. Common name: Appalachian Meadowrue, Maid-of-the-Mist. Phenology: May-Jul. Habitat: Rich forests. Distribution: A Southern and Central Appalachian endemic: s. PA, MD, VA, and WV south through w. KY and e. TN to w. NC and ne. GA.
ID notes: The roots are bright yellow.
Origin/Endemic status: Endemic
Taxonomy Comments: A preliminary study concluded that T. steeleanum B. Boivin is not distinct from T. coriaceum (Park 1988); further study is needed. T. steeleanum is alleged to differ in the following ways (and others): plant with long, cordlike rhizomes (vs. stout caudex), terminal leaflets mostly wider than long (vs. mostly longer than wide), achenes curved, 4-6 mm long (vs. less curved, 2.5-4 mm long). Park found these characters (and others) to be variable and to occur together within populations. It ranges from s. PA south through MD, e. WV, w. VA to nw. NC.

Horticultural Information
Intro: Erect perennial found in the understory of moist to somewhat dry forests, rich slope and floodplain forests; usually in moderately to strongly base-rich soils.
Stems: Stems slender, smooth, with a thickened, somewhat woody base.
Leaves: Leaves alternate, short-petiolate (with expanded, clasping bases), thick, 2-4 times divided into 3; the ultimate leaflets are oval to round, to 2 in. wide, with wavy or lobed tips.
Inforescence:
Flowers: Flowers in a loose, widely branched, pyramid-shaped panicle, on separate male and female plants. Flowers consisting of 5 inconspicuous greenish-pink sepals and, in male (staminate) flowers, dangling, maroon stamens bearing yellowish anthers, and in female (pistillate) flowers, maroon stigmas.
Fruits: Fruit a cluster of sickle-shaped achenes, each on a tiny stem.
Comments: A southern and central Appalachian endemic.
Height: 2-4 ft.
