  • Description & Ethnobotany
    • Plant Morphology :
      Growth Form: It is a trailing, twining, slightly hairy, non-woody plant.
      Foliage: Its alternate, stalked leaves are trifoliolate (bearing 3 leaflets). Its stalked leaflets have somewhat fleshy leaf blades that are broad or rounded, 5–14 by 4.5–10 cm, and with shortly-pointed or notched tips.
      Stems: The thick stem can grow to more than 2.5 cm in diameter.
      Flowers: Its flowering shoot is about 30 cm long and found at the leaf axils. Its purple flowers are sweetly-scented and notched at the tips.
      Fruits: Its fruits are dry, dehiscent pods (legumes), linear-oblong, 6–15 by 1.5–3 cm, and contain many dark brown seeds.
      Habitat :
      It grows along sandy seashores. It occurs locally in Pasir Laba Camp and Pulau Ubin (Chek Jawa).
      Associated Fauna :
      Its flowers are insect-pollinated.
      Cultivation :
      This drought and salt tolerant species is ideal for sunny locations with nutrient poor, but well-drained soils.  It has a fast growth rate, so it needs to be restrained by pruning. It can be propagated by seed.
      Etymology :
      Latin canavalia, after the Malabar vernacular name, kanavali, for these climbing herbs or sub-shrubs; Latin rosea, rose-like, possibly referring to the pink flowers.
      Ethnobotanical Uses :
      Edible Plant Parts (Edible Fruits; Edible Flowers; Edible Seeds)
      Food (Fruit & Vegetable: In northern Australia, the seeds and immature pods are used as food. Mature seeds are roasted or boiled before consumption. The flowers are edible.)
      [Others]: In many countries, this species is used to prevent soil erosion.
