Arrowhead

Arrowhead Sagittaria is well-named as its leaves are shaped like arrow heads. North American species grow in shallow water, rooted in the mud of lakes and ponds or in slow-moving streams. The flowers have three large white petals and they are either male or female (unisexual), having either stamens or a pistil but not both. There are about thirty species in the world. [CH] {GW}
