Description
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. [1]
Specfically, for Chameacrista fasciculata, the species is an annual herb, growing 1.5-6 dm tall from the taproot. The stems and branches are glabrous to more commonly densely puberulent with incurved trichomes and occasionally also with villous trichomes to 2 mm long. The leaves are sensitive with a sessile, depressed, saucer-shaped gland, 0.5-1.5 mm in diam. near the middle of the petiole. Leaflets 12-36, linear-oblong, 1-2.5 cm long, 2-6 mm wide, inequilateral; stipules persistent, striate. Inflorescence are 1-6 flowered axillary fascicle. Pedicels grow up to 1-2 cm long. Sepals are lanceolate in shape, growing 9-12 mm long, and are acute. Petals are bright yellow in color, almost equal, growing 1-2 cm long; stamens 10, unequal, growing 10-13 mm long. The legume are elastically dehiscent, growing 3-7 cm long, and 5-7 mm broad, and are glabrate or appressed-puberulent to villous. [1]
Distribution
C. fasciculata is native to the eastern United States, excluding Vermont, New Hampshire, and Maine, west to New Mexico, South Dakota, and Minnesota.[2]
Ecology
Habitat
C. fasciculata can be found in sandy savannas of the Gulf Coastal Plain, and bluffs, prairies, river bottoms and banks, and upland woods of the Great Plains region. Soils it generally grows on range from sandy to sandy loam soils.[3] As well, other wide range of soils include slightly acidic to moderately alkaline soils, and it prefers well drained and moderately lime soils.[4] It is a facultative upland species.[2] C. fasciculata is also a common colonizer of disturbed areas.[3]
Phenology
C. fasciculata has been observed flowering between April and September with peak inflorescence from June to August.[5]
Seed dispersal
This species is thought to be dispersed by consumption by vertebrates. [6]
Seed bank and germination
For propagation, seeds can be cold moist stratified for 56 days to improve germination success. Optimum soil temperature for germination is between 20 and 30 degrees Celsius. With this regiment, about 70% of seeds will germinate between 7 and 25 days.[3]
Fire ecology
Fire helps proliferate this species.[3]
Pollination
The following Hymenoptera families and species were observed visiting flowers of Chamaecrista fasciculata at Archbold Biological Station:[7]
Apidae: Apis mellifera, Bombus impatiens
Halictidae: Augochlora pura, Augochloropsis metallica, A. sumptuosa, Lasioglossum coreopsis, L. placidensis
Megachilidae: Coelioxys sayi, Megachile mendica, M. texana
Vespidae: Stenodynerus histrionalis rufustus
Use by animals
C. fasciculata has raised glands on its petioles that excrete a nectar that attracts predatory ants, with the presumed adaptive benefit of encouraging ants to prey on herbivores.[8] The glands have also been observed to attract bees and wasps, presumably with the same benefit to the plant.[9] As a whole, it is approximately 5-10% of the diet for large mammals, and 10-25% of the diet for terrestrial birds where it is found.[10] It is a major food item for the northern bobwhite quail and other quails due to its persistence through the winter and early spring. Partridge pea is also eaten by ring-necked pheasant, greater and lesser prairie-chicken, grassland birds, mallard, field mice, and deer; it can be poisonous for livestock and is considered potentially dangerous for cattle. Upland game birds and small non-game birds, small mammals, and waterfowl utilize the litter and plant stocks of the species for cover. As well, the common sulfur butterfly (Colias philodice) lays eggs on the leaves so that the larvae use them as their first food source. Historically, the Cherokee Native American tribe used the species as a medicinal drug to keep ball players from tiring as well as for spells of fainting; the Seminole tribe used C. fasciculata medicinally as a drug for nausea, and used the plant as a bed for ripening persimmons.[3]
Conservation and management
For management, stands that are already established are recommended to be disked lightly in springtime to show mineral soil that the seeds can germinate on. This species can decrease in frequency if there is not regular maintenance, so light disking is necessary to remove old sod, small brush, and other weeds. Fire is also a great management tool to help proliferate this species; for best results, prescribed fire should be conducted in the winter. Mowing can also help control weeds through mowing over the top of C. fasciculata individuals.[3]
Cultivation and restoration
To control erosion, C. fasciculata can be planted along road banks or stream banks for restoration as well as improving soil fertility. This is due to it being able to rapidly establish, fix nitrogen, to reseed, and decrease in frequency as other species start dominating the site. It is commonly included in seed mix with other grasses and forbs that are planted along roadsides to prevent establishment of weeds. Cultivars of C. fasciculata include 'Comanche' from the Knox City Plant Materials Center in Texas and 'Riley' from the Manhattan Plant Materials Center in Kansas.[3]
