Terminology
The botanical and common names for Sesbania bispinosa reflect its morphology and uses: Bispinosa: This part of the scientific name refers to the plant's characteristic of being prickly or spiny, as its stem and leaf rachis are often sparsely aculeate (prickly). Fabaceae: The plant belongs to this family, also known as the legume, pea, or bean family. All members of this family are characterized by their simple dry fruit (a pod or legume) and their ability to form root nodules that host nitrogen-fixing bacteria (Rhizobium). Dhaincha: The widely used Hindi and regional name for the plant, particularly in India and Nepal, where it is extensively cultivated as a green manure crop to enrich the soil. Dunchi Fiber: This refers to the strong, durable fiber extracted from the stem of the plant. This fiber is historically used to make ropes and fishing nets, often reputed to be superior to jute in durability and strength when used in water. Astringent: A key medicinal property mentioned for its leaves and flowers, meaning they cause the contraction of tissues and are useful in reducing inflammation or stopping superficial bleeding. Febrifuge: A traditional medicinal term, indicating that a preparation from the plant (like the plant decoction) is used to reduce fever.

Habitat and Distribution: Sesbania bispinosa is native to Asia and North Africa, but it is now widely distributed and naturalized throughout the humid and semi-arid tropics and subtropics globally. Ecology: It is particularly well-adapted to wet areas and heavy, waterlogged soils, and can also tolerate challenging conditions like alkaline or saline soils with low fertility. This resilience makes it a valuable crop for soil reclamation and marginal lands. It is also often found growing as a weed, particularly in rice paddies in cultivation areas. Cultivation Status: It is widely cultivated, especially in South and Southeast Asia (India, Nepal, Vietnam), mainly as a green manure and fodder crop, and is also harvested from the wild for local consumption and medicinal use. Seasonality: Being an annual or biennial plant, its growth cycle is typically completed within a year or two, with peak availability often coinciding with the monsoon and post-monsoon seasons where water is abundant.
External Look
Habit: Sesbania bispinosa is an erect annual or biennial shrub that grows quickly, reaching a height of 1 to 3 meters. Stem: The stem is generally glabrous (smooth) or only sparsely pubescent when young. A defining feature is its sparsely aculeate (prickly or spiny) nature. Under waterlogged conditions, the stem can develop a spongy mass of parenchyma. Leaves: The leaves are paripinnate (feather-like with an even number of leaflets), with a long rachis (central stalk) of 20–35 cm, which is also prickly. The numerous leaflets (50–110) are small, oblong, 10–20 mm long and 3–4 mm wide, with a rounded tip (obtuse) and a small point (mucronate). Flowers: The flowers are borne in a raceme (a cluster on a stalk) of 3–12 flowers, up to 13 cm long. The corolla (petals) is typically pale yellow and often flecked or mottled with violet or purple markings. The standard petal (vexillum) is about 12–13 mm long. Fruit (Pod): The fruit is a long, thin, glabrous (smooth) pod, approximately 15–25 cm long and 2–3 mm wide. Each pod contains a large number of seeds, typically 35–40 seeds. Seeds: The seeds are small and dark brown.
