Family
GenusDesmostachya
Speciesbipinnata (L.) Stapf
This species was originally described by and later transferred to the genus Desmostachya by Otto Stapf in 1900. It has several synonyms, including Eragrostis bipinnata L. and Uniola bipinnata L. The genus name Desmostachya derives from the Greek words desmos (bundle or bond) and stachys (spike or ear of grain), referring to the inflorescence's thread-like, bundled appearance. The specific epithet bipinnata comes from Latin, meaning "doubly pinnate," which describes the branching structure of the . Common names for Desmostachya bipinnata include halfa grass, big cordgrass, salt reed-grass, kusha, darbha, and durva.

Morphological characteristics

Desmostachya bipinnata, commonly known as kusha grass, is a rhizomatous grass in the family that forms dense tussocks through its geophytic growth habit, reaching heights of up to 1-2 meters. The plant exhibits robust vegetative propagation via elongated, scaly rhizomes, which produce basal innovations that are intravaginal and flabellate, contributing to its clumped, tussock-forming structure. The culms are erect and smooth, typically measuring 50-150 cm in length and 3-4 mm in , arising from the rhizomes and supporting the plant's upright . Leaves are predominantly basal, linear, and narrow, with blades 10-50 cm long and 2-6 mm wide; they are stiff, coriaceous, and coarse-textured, featuring scabrous margins, a membranous 0.5-1 mm long, and smooth, glabrous sheaths as wide as the blade at the collar. The is a dense, spicate up to 60 cm long, comprising numerous closely spaced, unilateral racemes 1-4 in length that spread from a central 15-40 cm long; each is 3-5 mm long and contains 5-10 florets. The fruit is a small, ovoid, trigonous without a sulcus, with an comprising 0.3-0.4 of its length and a punctiform hilum. The root system consists of extensive, fibrous roots extending up to 2 m in depth, with 50-55% concentrated in the top 10 cm of the soil, providing strong anchorage in various soil types.

Habitat and distribution

Natural range

Kusha grass (Desmostachya bipinnata) is native to arid and semi-arid zones across a vast expanse from northern and eastern Africa through the Arabian Peninsula and Middle East to South Asia and Southeast Asia, where it thrives in seasonally dry tropical biomes. In , its natural distribution includes countries such as , , , , , , , , , , , , and , often along desert fringes and riverbanks. The species extends through the , encompassing and , and into the with occurrences in , , , , , and . Further eastward, it is widespread in , including Pakistan, India (particularly in regions like , , and the West Himalaya), and , as well as Southeast in , , , , , and in . The grass has been introduced or naturalized in select areas outside its native range, notably in parts of such as the Cocos (Keeling) Islands, and in the Lesser Sunda Islands of . While reports of naturalization in Mediterranean exist, verified distributions remain limited to North African Mediterranean countries like , , , and rather than continental .

Ecological adaptations

Kusha grass (Desmostachya bipinnata), a perennial grass, exhibits notable through its extensive root system, which enables access to in arid environments. Secondary roots can penetrate up to 2 meters into the , allowing the to extract water from deeper layers during prolonged dry periods. This deep-rooted structure, combined with photosynthesis, enhances water-use efficiency by minimizing and optimizing carbon fixation under high temperatures and low water availability. The species also demonstrates salt tolerance, thriving as a in saline conditions through physiological mechanisms that allow survival in soils with up to 400 NaCl. This adaptation supports growth in coastal and inland areas with elevated salinity. Desmostachya bipinnata prefers well-drained soils such as sandy, loamy, or loamy-sand types, tolerating alkaline soils with pH ranging from approximately 7.5 to 9.3. It commonly establishes in fallow fields, roadsides, and riverbanks where soil disturbance and variable moisture occur. In its native ecosystems, Kusha grass plays a key role in , with its dense rhizomatous network binding soil particles to prevent in sandy and semi-arid landscapes.

Preparation and application

Kusha grass, known scientifically as Desmostachya bipinnata, is harvested from natural habitats such as river beds and plains during auspicious lunar phases to ensure its ritual purity. Traditionally, it is collected on the first day of the waning moon (Krishna Paksha Padyami), a time believed to enhance its spiritual potency, and often in the early morning when dew is present to preserve its purifying properties. The grass must be sourced from clean, unpolluted areas to maintain sanctity, with long blades up to 50 cm and a broad base of about 1 cm selected for optimal use. After harvesting, the grass undergoes processing to prepare it for ritual applications. Blades are sorted based on the number of leaves or stalks: single blades for death-related ceremonies, two for daily auspicious rituals, three for inauspicious non-death rites like offerings, and four for worship. They are then dried naturally and stored in bundles to prevent damage, with even-length blades typically used for weaving mats (asanas) and odd-length ones reserved for direct offerings. Rings, known as pavitras, are formed by twisting or plaiting two to seven blades together and knotting them into loops, often worn on the right during Vedic sacrifices to channel positive energies. In some preparations, the grass is boiled in water to create a purifying (kuśavāri). In ritual application, blades are oriented with their pointing eastward, toward the auspicious direction, to align with cosmic energies and facilitate purification. During ceremonies, the grass is infused with Vedic mantras to amplify its protective qualities, often arranged in borders around altars or fire pits to ward off negative influences. Quality is paramount: blades must be unbroken at the , symbolizing wholeness and , and entirely free from insects or blemishes to uphold efficacy. These techniques ensure the grass serves as a conduit for divine connection, such as in seating for priests or as a base for offerings in yajnas.
