Taxonomic notes
Synonyms: Sebastiania fruticosa (W. Bartram) Fernald; Sebastiania ligustrina (Michaux) Müller of Aargau.[1]
Varieties: none.[1]
Description
D. fruticosa is a perennial shrub/subshrub that is a member of the Euphorbiaceae family.[2]
This description was published in 1964 stating, Ditrysinia fruticosa is a "monoecious shrub, 1.5-2.5 m tall. Leaves alternate, elliptic to lance-elliptic, 3-7.5 cm long, 0.8-3.5 cm wide, entire; petioles 2-10 mm long, ciliate toward apex and on base of blade, with a pair of glandular stipules at base. Racemes 1-4 cm long, pistillate flowers 1-5 at the base, staminate numerous above. Sepals 3; petals absent; stamens 3; stigmas 3. Each flower subtended by a bract, on each side of which occurs a large gland. Capsule 3-locular, 6-6.5 mm long, broader than long. Seeds light brown, ovoid, 4.5-5 mm long; caruncle obsolete."[3]
Distribution
D. fruticosa is native to the southeastern coastal plain from southeast North Carolina south to central peninsular Florida and west to eastern Texas.[4]
Ecology
Habitat
Generally, D. fruticosa can be found in swamp forests as well as other moist to wet and mostly shaded habitats.[4] It has been observed in dry and loamy sand of a mesic woodland, on a shaded hardwood slope, in a shaded swale with various wetland vegetation, in a river swamp, in a floodplain forest, and on a shaded limestone bluff.[5] This species is listed as facultative and facultative wetland, where it mostly occurs in wetland habitats, but can also quite commonly occur in non-wetland habitats.[2] It is also a possible indicator of native groundcover and old fields of upland pine savannas in the Red Hills Region.[6]
D. fruticosa has had mixed responses to agricultural disturbances in southwest Georgia. In some areas, its occurrence increased while in others it decreased in response to agricultural disturbance and reestablished native pinelands.[7] It was also found to have variable changes in frequency in response to disturbance by KG blade in eastern Texas. D. fruticosa has shown a mix of regrowth and resistance to regrowth in reestablished native hardwood forests that were disturbed by KG blade. Additionally, it was found to have a decreased frequency in response to disturbance by roller chopping in eastern Texas. It has shown resistance to regrowth in reestablished pinewood forests that were disturbed by this practice.[8] D. fruticosa was found to be neutral in its short-term response to single mechanical soil disturbances.[9]
Associated species: Ilex glabra, Hypericum sp., Carex glaucescens, and other wetland species.[5]
Phenology
This species can be seen to flower from May until June and fruit from July to October.[4] It has been observed to flower from March to June with peak inflorescence in April and May.[10]
Conservation, cultivation, and restoration
D. fruticosa is critically imperiled in Arkansas and imperiled in North Carolina.[11]
