Sagittaria montevidensis is a species of flowering plant in the water-plantain family, Alismataceae, that is native to North and South America.[1] Common names include Giant Arrowhead and California Arrowhead. It is an aquatic plant that is found in shallow waters. The leaves are sagitatte and glabrous. Its terete, spongy petioles may reach a length of more than 0.75 m (2.5 ft). Inflorescences are typically shorter than the leaves and decumbent. Flowers are in whorls or pairs at nodes. They have three petals, each of which is white with a yellow base, and three green sepals. The thick pedicels are as long as 5 cm (2.0 in). Flowering occurs from June to September.[2]
