Collinsonia verticillata


Collinsonia verticillata is a woodland herb that grows from a hard, thickened rhizome. It produces flowers that range in color from white to pink and lavender in May and April. It produces fruit in June and July. There are 2-3 pairs of leaves, and unbranched inflorescence. It flowers with 4 stamens. The U.S. Forest Service, due to its limited range in the Southern Appalachian Mountains, has listed it as Sensitive. Very little is known about this species, although researchers have been able to successfully transplant mature plants to regional botanic gardens and arboreta for observation.

Conservation, Ecology & Research

Ecological Relationships
  None known.

Threats
  Opening of canopy through logging
Habitat destruction by road and residential construction
(Jess Peirson personal communication)

Current Research Summary
  Jess Peirson, an Ohio University graduate student, is studying the genus to verify the current species classification using morphology and DNA.
A.L. Fone studied seed output in various plant forms of this species in the 1980's.

Current Management Summary
  None known.

Research Management Needs
  General ecological, demographic and genetic variability research would be useful for this taxon.

Ex Situ Needs
  Seed germination studies--little to nothing is known currently.
