Description
"Perennial herb, 0.6-1.2 m tall (or shrub or tree up to 8 m high further south) with usually prickly brachlets. Leaves pinnately 3-foliolate; leatlets thinly chartaceous, glabrous, or nearly so, throughout, occasionally pricky beneath, hastately 3-lobed to widely deltoid, (2) 4-8 (12) cm long, stipellate. Inflorescence terminal, much elongate on usually leafless stems arising from the crown, (1) 3-7 dm long with few to numerous, papilionaceous flowers; pedicels 3-9 mm long, subtended by linear- lanceolate bracts 1-4 mm long and with 2 liner, caduceus bractlets, 1-2 mm long. Calyx glabrous, or nearly so, tubecampanulate, truncate, 5-11 mm long; the standard scarlet, 3-5.3 cm long, wings 5.5-11 mm long, keel 6-13 mm long; stamens diadelphous, 9 and 1; stigma capitate, ovary and stipe pubescent. Legume 7-15 (21) cm long, 1.2-1.6 cm broad, constricted between the several to many, scarlet seeds, stipe 1.5-4.5 cm long." [2]
The root system of Erythrina herbacea includes stem tubers which store non-structural carbohydrates (NSC) important for both resprouting following fire and persisting during long periods of fire exclusion.[3] Diaz-Toribio and Putz (2021) recorded this species to have an NSC concentration of 338 mg/g (ranking 11 out of 100 species studied).[3]
Distribution
This species is generally distributed from southeast North Carolina south to Florida, west to southeast Texas, and south into eastern Mexico.[4]
Ecology
Habitat
General habitats of E. herbacea includes dry sandy woodlands, maritime forests, and sandhills within the outer Coastal Plain region.[4] It occurs in sand pine woodlands, sandy hills, along edges of sinkholes, live oak-cabbage palm forests, uplands, hammocks, flatwoods, sand pine scrub, pine-palmetto scrub near ocean, longleaf pine-wiregrass savannas, shaded slopes of river bluffs, and in calcareous open prairies. Found in disturbed areas such as along roadsides, in understory of recently clear cut pine woodlands, and edges of woodlands. Can thrive in areas that are shady, semi-shady, or open. Is associated with areas that have sand soil types, sandy loam, loam, thin loamy sand, and calcareous soil types.[5] It is also considered an indicator species of the north Florida longleaf woodlands, and a characteristic species of the shortleaf pine-oak-hickory community type in the Red Hills region of north Florida and south Georgia.[6][7] E. herbacea was found to increase its occurrence in response to soil disturbance by agriculture. It has shown regrowth in reestablished native habitat that was disturbed by agricultural practices in southwest Georgia.[8] E. herbacea exhibits no response to soil disturbance by improvement logging in Mississippi.[9]
Associated species include Quercus geminata, Q. chapmanii, Q. incana, Osmanthus megacarpus, Ilex ambigua, Vitis rotundifolia, Serenoa repens, Persea, Myrica, Carya glabra var. megacarpa, Pinus palutris, Baccharis halimifolia, Rhus copalina, Callicarpa americana, Diospyros virginiana, Morus.[5]
Erythrina herbacea is an indicator species for the North Florida Longleaf Woodlands community type as described in Carr et al. (2010).[10]
Phenology
E. herbacea generally flowers from May until July.[4] It has been observed flowering from February to June with peak inflorescence in April and May, and fruiting from April to August.[5][11]
Seed bank and germination
Seeds germinate easily when scarified.[12]
Fire ecology
Is associated with annually burned pinelands.[5]
Pollination
Hummingbirds drink the nectar and pollinate E. herbacea.[12]
Herbivory and toxicology
E. herbacea is a food source seldom used by white-tailed deer as well as an introduced population of fallow deer in Georgia.[13][14]
Conservation, cultivation, and restoration
For general management, dead stem tips should be trimmed once new growth emerges in the spring when frost damage is visible.[12]
Cultural use
This species has toxic seeds for humans, which are used in Mexico for poisoning rats and various fish; the seeds are also made into novelties and necklaces which should be kept away from children.[12] The root of this plant has also been used medicinally as an expectorant, a sudorific, and a febrifuge.[15]
