Taxonomic notes
Synonyms: Lachnanthes tinctoria (J.F. Gmelin) Elliott; Gyrotheca tinctoria (J.F. Gmelin) Salisbury.[1]
Varieties: none.[1]
Description
L. caroliniana is a perennial monocot with slender rhizomes and notable red roots. The flower stalk can reach up to three feet tall and has gray hairs along the top.[2]
"Roots and rhizomes red. Stems pubescent only toward the inflorescence, glabrous below. Leaves 0.5-1.5 cm wide. Inflorescence convex. At first very compact and appearing head-like, expanding and become slightly open, the branches corymbosely arranged, each forming a compact helicoids cyme. Sepals 4-7 mm long, less than 1 mm wide, yellowish to brownish; petals 7-9 mm long, 1-1.5 mm wide, erect or slightly bent outward in age; stamens 3, exserted 1-2 mm, anthers at first straight, curling in age; styles slightly longer than the stamens; ovary inferior. Capsule oblate, 2-5 mm long, dehiscent to base. Seeds blackish brown, circular, 2-2.5 mm in diam., flat, surface uneven."[3]
Distribution
It can be found in coastal environments from Louisiana to Florida and north to Massachusetts, with disjunct populations in Tennessee, Virginia, and southern Novia Scotia, and can also be found in Cuba.[4]
Ecology
Habitat
Habitats are typically wet, acidic, nutrient-poor areas such as mesic and wet flatwoods, wet prairies, and seasonally inundated shorelines.[5] It can commonly be found in disturbed areas such as trails, ditches, fire lanes.[6] and has been observed by Jean Huffman to form dense stands following hog-rooting.
It can become a serious weed in cranberry bogs and newly established pastures.[7][8]
L. caroliniana does not respond to soil disturbance by clearcutting and chopping in North Florida flatwoods forests.[9] Furthermore, it was found to be neutral in its short-term response to single mechanical soil disturbances.[10]
Associated species include Panicum hemitomon, Hypericum edisonianum, and Panicum abscissum.[11]
Phenology
The white flowers are perfect and actinomorphic with a homoclamydeous imbricate perianth, 3 basifixed stamens, and an inferior, globose, slightly 3-lobed ovary [12] and arranged in a corymb.[7] The seed is a reddish 3 lobed capsule.[5] L. caroliniana has been observed to flower from May to July.[13]
Seed dispersal
Seeds are dispersed locally by gravity.[5]
Seed bank and germination
In the southern part of its range, it is capable of producing a substantial seed bank.[5] In an ex-situ germination experiment in the marsh banks of southern Georgia, seedling germination was significantly increased by adding nitrogen plus phosphorus to a moist environment.[14]
Fire ecology
It is observed growing in a pond pine/titi peat swamp that was burned by a lightning-set wildfire four months previously.[6] Hinman and Brewer (2007) observed L. caroliniana to have a reduction of flowering stalk density following a fire. This study also showed a significant decline between the initial and pre-fire census and a significant increase between the immediate and second post-fire census.
Herbivory and toxicology
L. caroliniana is an important food source to wigeons, gadwalls, pintails, sandhill cranes, and mallards, which eat the seeds and rhizomes (Landers et al. 1976). This species contains photodynamic toxins that limit herbivory by insects and some vertebrates but not waterfowl.[15] L. caroliniana has been observed to host assassin bugs such as Zelus cervicalis (family Reduviidae).[16]
Additionally, L. caroliniana has been observed at the Archbold Biological Station to host the following species:[17]
Bees from the family Apidae: Apis mellifera, Bombus impatiens, B. pennsylvanicus, Mellisodes communis
Sweat bees from the family Halictidae: Agapostemon splendens, Augochloropsis metallica, A. sumptuosa, Lasioglossum coreopsis, L. nelumbonis
Leafcutting bees from the family Megachilidae: Anthidiellum perplexum, Anthidium maculifrons, Coelioxys mexicana, C. octodentata, C. sayi, Megachile albitarsis, M. brevis pseudobrevis, M. georgica, M. mendica, M. petulans, M. texana
Thread-waisted wasps from the family Sphecidae: Philanthus ventilabris
Wasps from the family Vespidae: Polistes bellicosus, P. fuscatus
Conservation, cultivation, and restoration
Eutrophication from agriculture and urbanization has had a detrimental impact on Coastal Plain plant communities in Long Island and New Jersey.[18]
In Nova Scotia, it is listed as a threatened species.[4]
Cultural use
Historically, it was used by Native Americans as a narcotic and to treat ailments.[19]
