Taxonomic notes
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 [1].
Distribution
It can be found in coastal environments from Louisiana to Florida and north to Novia Scotia, and can also be foundin Cuba [2].
Ecology
Habitat
Habitats are typically wet, acidic, nutrient poor areas such as mesic and wet flatwoods, wet prairies, and seasonally inundated shorelines [3]. It can commonly be found in disturbed areas such as trails, ditches, fire lanes, 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 [4][5].
Phenology
The white flowers are perfect and actinomorphic with a homoclamydeous imbricate perianth, 3 basifixed stamens, and an inferior, globose, slightly 3-lobed ovary (Simpson 1988) and arranged in a corymb[4]. The seed is a reddish 3 lobed capsule[3]. It can divide by rhizomes, tubers, corms and bulbs [6].
Seed dispersal
Seeds are dispersed locally by gravity [3].
Seed bank and germination
In the southern part of its range, it is capable of producing a substantial seed bank [3]. In an ex situ germination experiment in the marsh banks of southern Georgia, it was found that seedling germination was significantly increased by adding nitrogen plus phosphorus to a moist environment (Gerritsen and Greening 1989).
Fire ecology
It has been observed growing in a pond pine/titi peat swamp that was burned by a lightning set wildfire four months previously (FSU Herbarium).
Pollination
The following Hymenoptera families and species were observed visiting flowers of Lachnanthes caroliniana at Archbold Biological Station (Deyrup 2015):
Apidae: Apis mellifera, Bombus impatiens, B. pennsylvanicus, Mellisodes communis
Halictidae: Agapostemon splendens, Augochloropsis metallica, A. sumptuosa, Lasioglossum coreopsis, L. nelumbonis
Megachilidae: Anthidiellum perplexum, Anthidium maculifrons, Coelioxys mexicana, C. octodentata, C. sayi, Megachile albitarsis, M. brevis pseudobrevis, M. georgica, M. mendica, M. petulans, M. texana
Sphecidae: Philanthus ventilabris
Vespidae: Polistes bellicosus, P. fuscatus
