Taxonomic notes
Named for A.W. Chapman, one of the southeast's best known early botanists [1].
Description
A description of Liatris chapmanii is provided in The Flora of North America.
L. chapmanii is a perennial species that grows from rounded to elongated corms[2][3]. The leaves are slightly curved, thin, and can be found along the flower stalk. The basal rosette is dense and has a whorled appearance. The puprle flowers are densely clustered along the flower stalk, with the stalk capable of reaching 3 feet tall [1].
Ecology
Habitat
In the Coastal Plain in Florida and Georgia, L. chapmanii can occur in longleaf pine sandhills and pine-oak-palmetto scrubs. It has been found in disturbed areas such as bulldozed pinelands and sandy fields. Soil types include loamy sand and red clay. Associated species include Quercus laevis, Ceratiola, Chrysopsis, Liatris gracilis, L. tenuifolia, Carphephorus odoratissimus, Balduina, Sporobolus, Lyonia, Myrica, Serenoa, Agalinis, and Dicerandra (FSU Herbarium).
Phenology
Flowers August through October (FSU Herbarium). The seeds are produced in cypselae fruits that have feathery bristle-like pappi[2].
Seed bank and germination
L. chapmanii occurs in pyrogenic scrub and sandhill communities and germination is stimulated by smoke (Lindon and Menges 2008).
Pollination
The following Hymenoptera families and species were observed visiting flowers of Liatris chapmanii at Archbold Biological Station (Deyrup 2015):
Megachilidae: Megachile albitarsis
