Description

Chamaecrista nictitans is a decumbent herb that forms large mats.

Generally, in the group Chameacrista it includes trees, shrubs, or herbs. The leaves are evenly 1-pinnate with conspicuous gland(s) on the petiole or rachis. The flowers are either solitary or clustered in axillary racemes or terminal panicles, perfect. The calyx has an inconspicuous tube, 5 lobed, equally imbricate, and often unequal. There are 5 petals and are a little unequal. The stamens 5-10, are often unequal and some are sterile or imperfect. The anthers are basifixed and opening by 2 apical pores. The legume is few-to many-seeded, often septate, and exceedingly variable. Including Chamaecrista Moench, Ditremexa Raf., Emelista Raf. [2]

Specifically, for Chamaecrista nictitans, the species is an annual, growing up to 1-5 dm tall from the taproot. The stems are glabrous to densley appressed-puberulent with incurved trichomes. The leaves are sensitive with a slender-stalked umbrella-shaped gland, about 0.4-0.8 mm in diameter. Just below the leaves are persistent, striate. The flowers are axillary, solitary, or 2-3 borne in a short raceme. The pedicels grow up to 1-4 mm long. The sepals are lanceolate, growing 3-4 mm long, acuminate. The petals are bright yellow in color, are very unequal, and the lowermost and largest is 6-8 mm long and about 2 times as large as the other four. There are 5 stamens, unequal. The legume is elastically dehiscent, growing 2-4 cm long, and 3-6 mm broad, and is glabrous to most commonly densely appressed-puberulent or rarely villous. [2]

Distribution

C. nictitans is widely distributed in the United States from Maine down the east coast to Florida, Michigan and Wisconsin, Kansas and Missouri, and as far west as New Mexico and Arizona.[3] It is also native to Puerto Rico, the Virgin Islands, Navassa Island, Mexico and portions of Central and South America, and introduced to Hawaii and the Pacific Basin as well as subtropics and tropics in Asia.[3][4] C. nictitans var. nictitans is more widely distributed in North America and into South America while C. nictitans var. aspera can be found from southeast South Carolina to south Florida[5] and the Bahamas.[6]

Ecology

It is a legume. By mid-season in June and July, a maximum nitrogen-fixing rate was observed.[7]

Habitat

C. nictitans is tolerant of overstory canopies that decrease the light level to about half the ambient (i.e., it can live in partially shaded areas and its nitrogen-fixing capability won't be significantly affected).[7] It is also tolerant of a wide range of dry to wet soil types, having been found in soils as diverse as sandy silt loam, low black sandy peat, shallow soil overlaying limerock, shell sand, red clay, loessial soil, sandy clay loam, dry marl, calcareous and shaly soils, clay, igneous intrusive rocky soils, and novaculite ridges.[8]

C. nictitans occurs in a variety of natural and disturbed communities. It is found in longleaf pine-wiregrass communities,[7] longleaf pine-scrub oak sandy ridges, annually burned savannas, xeric oak-saw palmetto scrub communities, wooded banks of creeks, slash pine flats, borders of brackish and salt marshes, low weedy swales, laurel oak woodlands, upland slopes, dry sandhills, margins of hillside bogs, and loblolly pine forests.[8] C. nictitans is also able to colonize some disturbed areas, including roadsides, railways, clear-cut pine flatwoods, vacant lots, cultivated fields, power line corridors, old fields, and plantations of young slash pine.[8] It responds positively to agricultural disturbance in South Carolina communities indicating post-agricultural woodland.[9][10] C. nictitans also responds positively to disking in Southern Georgia, especially in double-disked plots where its density was highest.[11] Furthermore, it responds positively to clearcutting and chopping in South Carolina.[12]

Associated species include Chamaecrista fasciculata, Panicum sp., Andropogon sp., Strophostyles leiosperma, Quercus sp., Serenoa repens, Pinus elliottii, Pinus taeda, Pinus palustris, Gordonia lasianthus, Schizachyrium scoparium, and Sorghastrum nutans.[8][13]

Chamaecrista nictitans is frequent and abundant in the Clayhill Longleaf Woodlands and Upper Panhandle Savannas community types as described in Carr et al. (2010).[14]

Phenology

It has been observed flowering in August through October with peak inflorescence in September, and fruiting in August through November.[8][15]

Seed dispersal

This species is thought to be dispersed by consumption by vertebrates. [16]

Seed bank and germination

For propagation, the seeds need scarification for successful germination. It has best results when boiled between 70 and 80 degrees Celsius, and seedlings can germinate within 6 weeks.[13]

Fire ecology

This species occurs in areas that regularly burn, suggesting a level of fire tolerance.[8] It has been observed to colonize an area post burn where it was either absent or rare before the fire disturbance.[17] A study found that C. nictitans benefited from winter and spring season burns rather than summer burns.[18] An additional study describing the effects of a seasonal fire regime on legume reproduction in longleaf pine savannas found that C. nictitans produced the greatest number of flowers after an instance of no fire (35.3) with the number decreasing slightly after a late winter/early spring burn (26.9) and dropping significantly after a lightning season burn (7.7).[19] The season of burning or presence of burning was not found to greatly impact the duration or timing of the synchronous peak for this species.[20]

Pollination and use by animals

Chamaecrista nictitans has been observed at the Archbold Biological Station to host sweat bees such as Augochloropsis sumptuosa (family Halictidae)[21] It has also been observed to host sweat bees from the Halictidae family such as Augochloropsis anonyma and A. aurata.[22][23] This species is not usually desired for grazing since it is slow to decompose, slow-growing, and can contain some toxicity. However, it is used for forage or hay in infertile subtropical soils, and is normally eaten by goats. C. nictitans is a great cover crop since it has the ability to build the nitrogen pool, organic matter in the soil, and increase overall availability of nitrogen. It is eaten by a variety of animals including eastern meadow lark, eastern mourning dove, bobwhite quail, and eastern turkey. The extrafloral nectaries on the plant attract spiders, ants, and pollinators. As well, it is a larval host for the little sulphur (Eurema lisa) and cloudless sulphur (Phoebis sennae) in the Lepidoptera order.

Diseases and parasites

C. nictitans is susceptible to nematodes, including Meloidogyne arenaria, M. incognita, and M. javanica.[24]

Conservation, cultivation, and restoration

C. nictitans can be considered weedy since it has the ability to easily spread to nearby fields, and especially in places where other competition is removed. For management of keeping the species, mowing off the other grasses and weeds that can outcompete C. nictitans along with lightly disking fields can alleviate this problem.[13]

Cultural use

Historically, the Cherokee Native American tribe utilized the species along with Cassia marilandica to be used to treat spasms in infants.[13] It was also used medicinally as a cathartic (helping bowel movements) and a vermifuge (expel worms).[25]
