Stellate hairy: Refers to hairs that are star-shaped, a common characteristic in the Malvaceae family.
3-5-costate: Indicates the presence of 3 to 5 main veins originating from the base of the leaf.
Cuneate at the base: The leaf base is wedge-shaped.
Caducous stipules: Small leaf-like structures at the base of the petiole that fall off early.
Antiphyllous: Flowers that grow on the opposite side of the stem from a leaf.
Torus: The part of the flower stalk where the petals, sepals, and other parts are attached.
Drupe: A fleshy fruit with a stony pit containing the seed, like a cherry or a peach.
Understanding this terminology is crucial for accurate botanical identification and for studying the plant's unique characteristics.
Availability and Habitat
Grewia tenax is widely distributed in arid and semi-arid regions of Africa and Asia, particularly in tropical and subtropical climates. It is a resilient plant that thrives in dry, rocky, and often nutrient-poor soils. It can be found in a variety of habitats, including savannas, grasslands, and rocky slopes. Due to its drought-tolerant nature, it is a significant component of the vegetation in desert and scrubland ecosystems. While it is not commercially cultivated on a large scale for its fruit like its relative Grewia asiatica (Phalsa), it is commonly harvested from the wild in many communities. Its availability is seasonal, with fruits typically appearing after the flowering period.
External Look
Grewia tenax is a visually distinct shrub, growing up to 3 meters tall.
Stem: The bark is a characteristic ash-grey color, and young twigs are covered in stellate hairs.
Leaves: The leaves are relatively small, ranging from 0.6 to 4.5 cm long, and have an ovate-elliptic or obovate to almost orbicular shape. They are sharply serrated along the edges and are covered in fine, star-shaped hairs.
Flowers: The flowers are a striking feature, appearing solitary or in pairs. They are typically white, sometimes with a yellowish-white tinge, and are about 2 to 2.5 cm across. The sepals are linear-oblong and stellate hairy on the outside.
Fruit: The fruit is a small, lobed drupe, typically with 2 to 4 lobes, each about 5-7 mm in diameter. It is initially orange-yellow and develops a reddish tinge as it ripens. The surface of the fruit is glabrous (smooth) or has a few scattered hairs.
This unique combination of features makes Grewia tenax easily recognizable in its natural habitat.
