Description
Perennial herb with erect, hairless stems 20 - 40 inches (50 - 100 cm) tall. Leaves with long leaf stalks, each leaf divided into several, leathery, lance-shaped, coarsely toothed leaflets. Flower clusters flat-topped, composed of 5 - 12 smaller clusters of tiny, white flowers; flower stalks hairless. Flowers with 5 white, spreading petals. Fruit about ¼ inch (5 - 6 mm) long, hairless, oval, flattened, ribbed, and winged.[1] Flowers are arranged in umbels and are compound and bisexual.[2]
Distribution
It is found in southwest and south-central Georgia and in the eastern part of the panhandle of Florida.[3]
Ecology
Habitat
A. dentata is restricted to native groundcover and is commonly associated with upland pinelands of South Georgia.[4] Habitats include sandhills, longleaf pine-wiregrass savannas, longleaf-scrub oaks, boggy areas, and pine flatwoods. It occurs in disturbed areas such as roadsides and logged fields. Thrives in areas that are open or semi-shaded. Soils include dry sand, gravelly soil, loamy sand and dry and moist loamy soil.[5][3]
Associated species: Croton sp., Pinus palustris, Quercus laevis, Q. margaretta, Rhynchosia sp., Symphyotrichum dumosum, Carphephorus odoratissiumus, C. paniculatus, Chrysopsis sp., and Symphiotrichum dumosum'.'[5]
Phenology
Angelica dentata has been observed to flower June through January.[5][6]
Seed dispersal
Seeds are dispersed by gravity and small animals.[1]
Fire ecology
It can be found in frequently burned areas such as longleaf pine savannas.[5]
Pollination
Pollinated by wasps, flies, beetles and bees.[1] In Franklin County, FL, wasp pollinators include those from Vespidae.[7]
Conservation and management
Threats include conversion of habitat to pine plantations, agriculture, pastures, development and fire suppression.[1]
Cultivation and restoration
