Hottonia inflata (American Featherfoil)

Many thanks to Stephen, Pete and Casey for introducing me to this special plant this spring. Hottonia inflata, or American featherfoil, is ranked as imperiled (S2) in the state of Missouri and is a species of conservation concern in most states within its range. The destruction of wetlands habitats in the U.S. is the cause of the scarcity of this winter annual member of the primrose family (Primulaceae). The stems of this plant are spongy organs filled with air pockets and are the characteristic described in the specific name – inflata.

The gas-filled stems and leaves of Hottonia inflata allow this aquatic member of the primrose family to keep its flowers above the water’s surface.
