Description
Angelica dentata is a perennial herb with erect, hairless stems growing 20 - 40 inches (50 - 100 cm) tall. The leaves grow on long leaf stalks, each leaf divided into several, leathery, lance-shaped, coarsely toothed leaflets. The flowers grow in flat-topped clusters, composed of 5 - 12 smaller clusters of tiny, white flowers. The flower stalks are hairless, and flowers themselves have 5 white, spreading petals. The fruits are about 1/4 inch (5 - 6 mm) long, hairless, oval, flattened, ribbed, and winged.[2] Flowers are arranged in umbels and are compound and bisexual.[3]
Distribution
It is found in southwest and south-central Georgia and in the eastern part of the panhandle of Florida.[1] However, one study found the presence of A. dentata in south Alabama.[4]
Ecology
Habitat
A. dentata is restricted to native groundcover and is commonly associated with upland pinelands of South Georgia. It was found to decrease in coverage in response to agricultural disturbance in southwest Georgia. Additionally, it has shown resistance to regrowth in reestablished pine communities that had been disturbed by agricultural practices.[5] 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.[6][1]
Angelica dentata is an indicator species for the Panhandle Silty Longleaf Woodlands community type as described in Carr et al. (2010).[7]
Associated species: Croton sp., Pinus palustris, Quercus laevis, Quercus margaretta, Rhynchosia sp., Symphyotrichum dumosum, Carphephorus odoratissiumus, Carphephorus paniculatus, Chrysopsis sp., and Symphiotrichum dumosum.[6]
Phenology
Angelica dentata has been observed to flower June through January.[6][8]
Seed dispersal
Seeds are dispersed by gravity and small animals.[2]
Fire ecology
Angelica dentata can be found in frequently burned areas such as longleaf pine savannas.[6] Populations have been known to persist through repeated annual burns.[9]
Pollination
Angelica dentata is pollinated by wasps, flies, beetles and bees.[2] In Franklin County, FL, wasp pollinators include those from the family Vespidae.[10]
Conservation, cultivation, and restoration
Threats include conversion of habitat to pine plantations, agriculture, pastures, development and fire suppression.[2] This species should avoid soil disturbance by agricultural practices to conserve its presence in pine communities.[5]
