Nymphaea odorata, also known as the Fragrant Water Lily and Beaver Root, is an aquatic plant belonging to the genus Nymphaea. It can commonly be found in shallow lakes, ponds, and permanent slow moving waters throughout North America where it ranges from Central America to northern Canada.

Description[edit]

This plant is rooted from a branched rhizomes which gives rise to long petioles which terminate in smooth floating leaves. Since the leaves are subject to tearing by water and waves, they are round with a waxy upper coating that is water-repellent.[1] The flowers also float. They are radially symmetric with prominent yellow stamens and many white petals. The flowers open each day and close again each night and are very fragrant. Once the flowers are pollinated, the developing fruit is pulled back under water for maturation.[2]

Plant systematists often use it as a typical member of Nymphaeaceae, which (other than Amborella) is the most basal of the flowering plants.[3]

It is cultivated in aquatic gardens as an ornamental plant. It is invasive and weedy on the west coast of North America.

Chemistry[edit]

The lignans nymphaeoside A and icariside E, and the flavonols kaempferol 3-O-alpha-l-rhamnopyranoside (afzelin), quercetin 3-O-alpha-l-rhamnopyranoside (quercitrin), myricetin 3-O-alpha-l-rhamnopyranoside (myricitrin), quercetin 3-O-(6'-O-acetyl)-beta-d-galactopyranoside, myricetin 3-O-beta-d-galactopyranoside and myricetin 3-O-(6'-O-acetyl)-beta-d-galactopyranoside can be found in N. odorata.[4]
