  • Description & Ethnobotany
    • Plant Morphology :
      Growth Form: Aquatic herbs arising from rhizomes reaching to about 1.5 m tall (maximum height of 2 m) that live in marshes or along river edges.
      Roots: Rhizomes are coarse and produce tuber. 
      Foliage: Emersed leaves are lance –shaped, basal, long-petiolate (44 – 58 cm). Leaf blades ranged from linear to ovate or elliptic, about 0.7– 16 cm wide with a thick mid rib. Leaf morphology and length vary with amount of phosphorous level in the soil, hence acting as potential indicator of nutrients limitation. 
      Flowers: Emersed inflorescence is raceme and has 6 to 13 whorls with white flowers in whorls of 3. Each flower is 3.3 cm wide. There are 3 sepals which are recurved to spreading in staminate flowers; not enclosing flower or fruit head. Bracts are lanceolate to ovate-lanceolate, acute to acuminate at the apex and ranged from 0.5 to 1 inch. 
      Fruits: Brown obovoid to oval achenes about 1.5 to 2.7 mm long, 1.22 mm wide; are flat, beaked, and winged. Achenes have a grooved surface which increases its surface area in contact with water, thus increasing their floatability. 
      Etymology :
      Sagittaria refers to the leaf-blade of the plant, which is shaped like the point of an arrow. 
      lancifolia come from the Latin word "lancifolius" meaning to have leaves shaped like a lance-head. 
      Ethnobotanical Uses :
      Edible Plant Parts (Edible Roots)
      Food (Fruit & Vegetable: The root can be eaten raw or cooked and tasted like sweet chestnut when roasted. The tuber can be dried and ground into a powder and used to make bread.)
      Medicinal (The roots are used as a digestive and treatment of wounds and sores.)
