This family includes four genera, each with its own unique characteristics and distribution. Let’s delve into the world of Saururaceae, exploring their common names, native regions, general characteristics of the genera, major species, and other noteworthy information.
Common Names and Native Regions:
The Saururaceae family is commonly referred to as the Lizard’s Tail family due to the resemblance of some species’ inflorescence to the shape of a lizard’s tail. They are mainly native to eastern Asia and eastern North America. Some common names for the plants within this family include Lizard’s Tail, Lizard’s Tail Plant, and Water Dragon.
General Characteristics of the Genera:
The Saururaceae family comprises four genera:
Anemopsis: This genus includes a single species, Anemopsis californica, also known as Yerba Mansa. It is a perennial herb native to southwestern North America. Yerba Mansa has unique, cone-like flower spikes and aromatic leaves.
Gymnotheca: The genus Gymnotheca consists of herbaceous plants native to Central and South America. These plants have simple, alternate leaves and small, inconspicuous flowers.
Houttuynia (Chameleon Plant): The genus Houttuynia includes one well-known species, Houttuynia cordata, also known as the Chameleon Plant or Fish Mint. Houttuynia is more herbaceous and often considered a ground cover. It has heart-shaped leaves with prominent veins, and the leaves come in various colors, including green, red, and variegated patterns.
Saururus (Lizard’s Tail): The genus Saururus includes herbaceous plants that grow in moist to wet habitats, such as marshes, swamps, and along riverbanks. They are often found in riparian zones, where their roots can be partially submerged in water. The plants typically have simple, ovate leaves with a cordate or arrowhead shape at the base. One of the distinctive features of Saururus is its unique inflorescence, which can resemble a lizard’s tail, with elongated and slender white or greenish-white flowering spikes.
