What are the morphological characteristics of this plant?
Crotalaria sessiliflora has an erect, herbaceous growth habit characterized by branched stems, trifoliate leaves with oblong to elliptical leaflets, and sessile yellow flowers that lack a distinct pedicel. The leaves are typically arranged alternately along the stem and feature entire margins with a smooth texture. Its floral structure consists of a bright yellow corolla that is slightly irregular in shape, typical of the Fabaceae family. The inflorescence emerges directly from the leaf axils, giving the plant its sessile characteristic. Following pollination, the plant produces distinctive, inflated legume pods that contain several small seeds.
What is the geographical distribution of this plant?
This plant is native to the tropical and subtropical regions of the Americas, spanning from the southern United States through Central America and into South America. It is most frequently documented in parts of Mexico and the Caribbean islands. Its range extends significantly southward into countries such as Brazil and Argentina. The species thrives in various warm climates where it can colonize disturbed habitats and open grasslands. This widespread distribution is supported by its ability to adapt to diverse lowland environments across the Western Hemisphere.
How is this plant cultivated?
This plant is cultivated primarily as a green manure or cover crop in tropical and subtropical agricultural systems to improve soil nitrogen levels.
Growers typically sow the seeds directly into prepared soil during the onset of the rainy season to ensure adequate moisture for germination.
