Natural range of Collinsonia anisata from Weakly [1]

Common Names: southern horsebalm; anise horsebalm[2]

Taxonomic Notes

Synonyms: C. canadensis var. punctata; Collinsonia punctata[2]

The taxanomic identification of this species seems highly debated in the literature, making a specific description that differentiates it from other species difficult. Collinsonia anisata is almost identical to Collinsonia punctata except for having a scent of aniseed and the number of stamen (four).[3][4] In a 2006 manuscript, C. anisata is suggested to be distinct species of C. serotina by containing 4 stamen, rather than 2.[5]

Description

A South Carolina specimen from 1806 was described as having erect, lightly hairy stems of 2-3 ft (0.61-0.91 m) high. Leaves are petioled, cordate to ovate, acuminate, crenate-dentate, pale underneath, and covered with pellucid dots. Inflorescence contain compound terminal racemus with simpler axillary ones. Seeds are globular.[3]

Distribution

This species occurs from central Georgia, southwest to the Florida panhandle, and westward to southern Mississippi.[2][5]

Ecology

Habitat

C. anisata is found in rich forests.[2]

Phenology

In the southeastern and mid-Atlantic United States, C. anisata flowers from late July through September and fruits from September through October.[2]
