Taxonomic notes

Varieties: none


C. floridana is an erect perennial herb arising from a fleshy tap root and can reach three feet in height.[1] All parts of the plant are covered with sticky hairs and leaves are alternately arranged.[2] It is a nitrogen fixer.[3]


It is endemic to Florida.[2]



In the Coastal Plain in Florida, C. floridana has been found in turkey oak/longleaf pine sand ridges; pine-palmettos flatwoods; longleaf pine-wiregrass ridges; and scrub oak sand ridges. It is found in large populations in highly disturbed areas compared to undisturbed areas, making it unusual from other Florida endemic scrub species which are sensitive to disturbance[3]. Populations have been found in disturbed areas such as heavily cattle grazed longleaf pine-saw palmetto flatwoods, roadsides, and pastures.[3][4]


Flowers are yellow and orange and are composed of three petals.[2] C. floridana has been observed flowering April through August and fruiting in May.[4][5]

Fire ecology

Carrington (1999) found C. floridana to be a strong re-sprouter after fire, however it did not show a strong flowering response.[6] Seedlings were only present for five months post-fire, suggesting a weak seedling establishment after fire.[6] Populations have been observed to be low in undisturbed, burned areas.[3]


Bombus impatiens and Augochloropsis are the major visitors to C. floridana. They have been observed ripping holes in the sides of the keel petals of the flower and vibrating their wings to get pollen out of the floral tube. Pollinators visitation rates are affected by temperature, flower size, and flowering density.[3]

The following Hymenoptera families and species were observed visiting flowers of Chapmannia floridana at Archbold Biological Station:[7]

Apidae: Bombus impatiens

Halictidae: Augochlorella aurata, Augochloropsis metallica, Lasioglossum nymphalis, L. placidensis
