| Family | Scientific Name | Common Name | Habitat | Distribution | Image |
|---|---|---|---|---|---|
| Ranunculaceae | Thalictrum amphibolum | Skunk Meadowrue, Waxy Meadowrue | Mesic to dry forests, woodlands, barrens, and prairies, over hornblende, greenstone, dolostone, and serpentinized olivine. | QC and ON south to n. FL, LA, and TX, and scattered southwest to CO, NV, and AZ. |  |
| Ranunculaceae | Thalictrum arkansanum | Arkansas Meadowrue | Bottomland forests, especially calcareous, sometimes in mesic or submesic upland situations. | Endemic to AR, se. OK, and ne. TX. |  |
| Ranunculaceae | Thalictrum clavatum | Lady-rue, Mountain Meadowrue | Seepages, moist forests, spray cliffs at waterfalls, brookbanks. | A Southern Appalachian endemic: VA, WV, e. KY south through w. NC and e. TN to nw. SC and n. GA; all records of this species for AL are apparently T. mirabile (D. Spaulding, pers.comm, 2013). |  |
| Ranunculaceae | Thalictrum cooleyi | Cooley's Meadowrue, Savanna Meadowrue | Ecotones between calcareous savannas and adjacent swamp forests, shallowly underlain by coquina limestone ("marl"), generally within a few meters of both Taxodium ascendens and Liriodendron tulipifera. | The species is endemic to two small areas, centered around Maple Hill (Pender and Onslow counties, NC) and Old Dock (Columbus and Brunswick counties, NC), with a small disjunct population in Panhandle FL (Walton County), and a small number of ambiguous populations in sw. GA (Dougherty and Worth counties); the GA populations are assigned here for now but may well represent a new taxon. |  |
| Ranunculaceae | Thalictrum coriaceum | Appalachian Meadowrue, Maid-of-the-Mist | Rich forests. | A Southern and Central Appalachian endemic: MD, VA, and WV south through w. KY and e. TN to w. NC and ne. GA |  |
| Ranunculaceae | Thalictrum dasycarpum | Purple Meadowrue | Forest, woodlands, and prairies. | QC and YT south to PA, KY, TN, nw. GA, AL, MS, LA, TX, NM, AZ, and WA. It has been reported for scattered localities in VA (Harvill et al. 1992); Park (1992) and FNA do not document the occurrence of T. dasycarpum in VA. These are likely misidentifications; substantiation is needed. |  |
| Ranunculaceae | Thalictrum debile | Trailing Meadowrue | Moist to wet forests over limestone. | Nw. GA west to e. MS. |  |
| Ranunculaceae | Thalictrum dioicum | Early Meadowrue, Quicksilver-weed | Seepages, moist forests. | ME, QC, and MN south to SC, c. GA, AL, MO, and nc. AR. |  |
| Ranunculaceae | Thalictrum hepaticum | Appalachian Tall Meadowrue | Seepage areas. | PA south to n. GA and se. TN, strictly or primarily in the Appalachians. | |
| Ranunculaceae | Thalictrum macrostylum | Small-leaved Meadowrue | Moist places, perhaps associated with circumneutral soils, moist to dry ultramafic outcrop barrens (over serpentinized olivine), tidal freshwater marshes, rarely pineland seepages with calcareous substrate. | Se. VA south and west through NC, SC, sc. GA, FL, and AL to MS. |  |
| Ranunculaceae | Thalictrum mirabile | Rockhouse Meadowrue | Wet sandstone cliffs, primarily in the Cumberland Plateau (and especially associated with sandstone rockhouses). | KY south through TN to n. AL and nw. GA (and additionally cited in FNA as occurring in w. NC, a record that is apparently erroneous, presumably based on misidentification of T. clavatum). |  |
| Ranunculaceae | Thalictrum pubescens | Common Tall Meadowrue, Late Meadowrue, King-of-the-Meadow | Bogs, marshes, wet forests. | NL (Labrador), NL (Newfoundland), and ON south to GA, SC and MS. |  |
| Ranunculaceae | Thalictrum texanum | Houston Meadowrue | Endemic in se. TX. |  | |
| Ranunculaceae | Thalictrum thalictroides | Rue-anemone, Windflower | Moist forests. | ME, MN, and KS, south to Panhandle FL, MS, AR, and OK. |  |
