Taxonomic Notes

Synonym: C. serotina;[2][3] C. canadensis var. punctata; Hypogon verticillata; Micheliella anisata[3]

The taxanomic identification of this species seems highly debated in the literature.[4] Collinsonia punctata is almost identical to Collinsonia anisata except for its different scent and the number of stamen (two).[5][6] In a 2006 manuscript, C. punctata is recognized as having two stamens instead of four and being an intermediate between C. canadensis and Collinsonia anisata.[4]

Description

Collinsonia punctata is a dioecious perennial forb/herb.[3]

Distribution

This species occurs from southern South Carolina to eastern Louisiana along the coastal plain.[2]

Ecology

Habitat

C. punctata is found in rich woods.[2]

Phenology

In the southeastern and mid-Atlantic United States, flowering occurs in late August to mid-October and fruiting from September through October.[2]

Use by animals

C. serotina composes 2-5% of the diet for some terrestrial birds.[7]
