Trautvetteria fonticalcarea is a species of flowering plant in the family Ranunculaceae. It is endemic to northeastern Tennessee in the southeastern United States.[2]
Trautvetteria fonticalcarea is a rhizomatous perennial herb (forb) with basal and alternate leaves and small white, actinomorphic flowers.[3] Basal leaves are shallowly 3- (occasionally 5-) lobed with rounded or deltoid lobes, coriaceous texture, and crenate to dentate margins, with strongly reticulate venation.[4]
Habitat and ecology
The species is restricted to highly specialized calcareous wetland habitats, particularly dolomitic seeps and fens associated with groundwater discharge systems.[1][4] It occurs in hydric, alkaline soils derived from dolomite and is considered a habitat specialist with narrow ecological requirements.[3]
Distribution
Taxonomy
Trautvetteria fonticalcarea was described by Aaron J. Floden in 2017 (published 2018) in Nordic Journal of Botany.[5] The type specimen was collected in Campbell County, Tennessee, and is deposited at the University of Tennessee Herbarium (TENN), with isotypes distributed to multiple herbaria.[5]
The species was previously included within Trautvetteria caroliniensis but is now recognized as distinct based on morphological characters and its restriction to calcareous seepage habitats.[4]
