    • Taxonomy: (L.) Sm.
    • Presence: Two field sites targeted for eradication, first record from Horseshoe Lake, Hawkes Bay in 1975
    • Habitat: Still and slow flowing water bodies
    • pH range: 6.8 - 7.0
    • Hardness (ppm): 50 - 80

The submerged leaf is very thin and lettuce-like. Flower is golden yellow with 6 petals and up to 6 cm across with a strong alcoholic aroma. The flower is held above the water surface by a stout stalk.
