Taxonomic Notes

Varieties: R. cuneifolius var. angustior; R. cuneifolius var. subellipticus; R. cuneifolius var. spiniceps[2]
; R. sejunctus L.H. Bailey

Synonyms: R. chapmannii; R. dixiensis

Description

Rubus cuneifolius is a dioecious perennial subshrub.[2]

Rubus cuneifolius does not have specialized underground storage units apart from its taproot.[3] Diaz-Toribio and Putz (2021) recorded this species to have an non-structural carbohydrate concentration of 60.3 mg/g (ranking 44 out of 100 species studied) and water content of 57.1% (ranking 59 out of 100 species studied).[3]

According to Diaz-Torbio and Putz (2021), Rubus cuneifolius has taproots with a below-ground to above-ground biomass ratio of 11.8 and nonstructural carbohydrate concentration of 60.3 mg g-1.[4]

Distribution

R. cuneifolius is found primarily on the coastal plains from Connecticut and New York south to Florida, Alabama, Mississippi and Louisiana.[1][2]

Ecology

Habitat

R. cuneifolius has been found in wooded floodplains, hardwood forests, turkey oak ridges, Native American mounds, and longleaf pinelands. It is also found in disturbed areas including along nature trails, along firebreaks, cut over pine flatwoods, roadsides, and dump borders.[5] R. cuneifolius is an indicator species for the Clayhill Longleaf Woodlands community type as described in Carr et al. (2010).[6] R. cuneifolius has shown regrowth in reestablished woodlands that were disturbed by agriculture in South Carolina coastal plain communities, making it a possible indicator species for post-agricultural woodlands.[7] R. cuneifolius uses a medium amount of water, occurs in full sunlight to partial shade, and has a medium tolerance to calcium carbonate.[8] A study in the Great Dismal Swamp, Virginia, found R. cuneiolius was present in uncut-burned areas with a mean biomass of 1.16 g m-2 yr-1.[9] Additionally, a study exploring longleaf pine patch dynamics found R. cuneifolius to be most strongly represented within the gaps of longleaf pine forests.[10]

Associated species: Pinus elliottii.[11]

Phenology

R. cuneifolius has been observed to flower between March and June with peak inflorescence in April,[1][12] with fruiting occurring from May through July.[13] R. cuneifolius produces a white conspicuous flower.[8] The timing of flowering has been shown to be sensitive to ozone levels where elevated levels cause earlier flowering but produce fewer large ripe fruits.[14] Standing crops of fruit in Georgia flatwoods peaked at 114.5 g Dm-2 with 52% of plots containing fruit in 5 year old plantations.[15] It typically does not flower and fruit until the second year following fire.[16]

Seed dispersal

This species is thought to be dispersed by consumption by vertebrates.[17] Seeds of R. cuneifolius are likely primarily dispersed by migrating birds and deer which consume the fruits.[18]

Seed bank and germination

Seeds of R. cuneifolius were commonly observed in Georgia seed banks of longleaf pine - wiregrass - bracken fern forests maintained by annual spring burns since 1961.[19] Annual disking of fallow fields in different months also did not affect the presence of Rubus cuneifolius suggesting an abundance of seeds in the seed bank.[20]

Fire ecology

R. cuneifolius readily resprouts following fire and is often found in burned areas as seedlings germinating from the seed bank,[19] but it appears to be somewhat intolerant of long-term competition with later successional fire-tolerant perennials.[21] Removal of fire from old-field pineland for 44 years did not produce an increase in R. cuneifolius frequency, but rather a decrease from 80 individual in 1966 to 69 in 2013.[22] Populations of R. cuneifolius have been known to persist through repeated annual burns.[23][24][25]

Pollination

R. cuneifolius is recognized to attract a large number of native bees for pollination.[8]

Herbivory and toxicology

Berries produced by R. cuneifolius are highly palatable by browsing animals, composing 10-25% of the diet for many species of terrestrial birds, large mammals and small mammals. It is also an occasional source of cover for small mammals and terrestrial birds.[2] Because R. cuneifolius fruits in the late summer, it is likely an important source of energy for fall migrating bird species.[13] Besides attracting pollinators, R. cuneifolius is known for providing nesting materials/structure for native bees.[8]

Diseases and parasites

R. cuneifolius hosts several species of thripes (Frankliniella spp.) which are tiny insects (1 mm or less) that feed on new plant growth producing cosmetic damage and sometimes transmitting diseases to the plant.[26]

Conservation, cultivation, and restoration

Cultural use

Historically, in Appalachia, tea from the roots was used to treat cold symptoms, and the same tea or juice from the fruit was used to cure dysentery.[27]

The entire plant can be consumed in various ways, but the fruits are especially popular to eat fresh or to make jellies and drinks.[28]
