Water plantain ( Alisma plantago-aquatica) thriving in the Lambrok Tributary
Its small, pale, three-petalled flowers grow on slender branching stems that radiate out from a tall central stalk. The flowers open in the afternoon and early evening, attracting small flying insects. The leaves are lanceolate (spear-shaped) with parallel veins.
Water plantain grows in the muddy margins of slow moving streams. Its clusters of leaves are important habitat for flying insects that spend part of their life cycle in the stream.
Conservation status: common and widespread.
