Limosella granitica, Family Scrophulariaceae, also known as Granite Mudwort, is an aquatic perennial, occasionally with a conspicuous stolon. Its leaves are 3Ð8 cm long, with the blade often floating on the surface of the water. The leaf blade is obovate, 6Ð20 mm long, 2Ð4.5 mm wide, attenuated at the base and rounded at the apex. The flower stalks (pedicels) are generally 10Ð22 mm long. The calyx is 2Ð3 mm long and red-purple in colour; the corolla is white; the anthers are black with white pollen. The capsules (fruit) are downturned into the silt, 3.2Ð4.8 mm long and 2.5Ð3.5 mm wide, and dark brown in colour. Flowering occurs mainly from September to October. Seeds are narrow-oblong, 0.9Ð1.1 mm long and dark brown (Barker, 1984).
