Stipa capensis

Stipa capensis is an annual herbaceous plant of the grass family (Poaceae). It is an important winter wild grass in desert and semi-desert regions, and it appears abundantly after rainfall. It is characterized by its long-stemmed spikes.



General Description



It grows as an upright herb consisting of small to medium-sized clumps, and usually reaches a height of about 20–50 cm. The stems grow from the base of the plant, become denser during the wet season, and then dry out after the life cycle is complete.



Papers



Its leaves are narrow and linear, green to bluish-green, and may be curled or slightly rough. The leaves emerge from the base of the plant and on the stems, and turn yellow or straw-colored when dry.



Inflorescences and flowers



It produces slender spike-like inflorescences, bearing spikelets with long, prominent stalks. The inflorescence is initially green, then turns straw-yellow or light brown upon maturity, and the long stalks give the plant a distinctive appearance.



Fruits and seeds



It produces small grains within the spikelets, attached to awns that aid in wind dispersal. The awns can also help the grain move through the soil or adhere to animal fur, thus contributing to plant spread.



Endurance and suitability



It adapts well to drought and heat, and has a relatively short life cycle that allows it to take advantage of seasonal rains. It grows in sandy, gravelly, and light clay soils, as well as in plains and open areas.



Uses



It has pastoral and environmental importance, and is considered a grazing herb that benefits livestock and wildlife during its green growth period. It also contributes to soil covering and erosion reduction, and its dry remains become part of the soil's organic matter.



natural spread



Stipa capensis is widespread in North Africa, the Mediterranean basin, the Middle East and the Arabian Peninsula, and is associated with desert, semi-desert, plains and sandy and gravelly areas.



Preservation status



Stipa capensis is not known to be globally threatened and has a relatively wide distribution. Its density varies from season to season depending on rainfall, grazing pressure, and habitat condition.
