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 responds both positively and negatively to soil disturbance by roller chopping and negatively to disturbance by a KG blade in East Texas Loblolly Pine-Hardwood Forests.[7]
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.[8]
Conservation, cultivation, and restoration
D. fruticosa is critically imperiled in Arkansas and imperiled in North Carolina.[9]
