Smilax rotundifolia, also known as roundleaf greenbrier [2] or common greenbrier, is a woody vine native to the southeastern and eastern United States and eastern Canada. [1] [3] [4] It is a common and conspicuous part of the natural forest ecosystems in much of its native range. The leaves are glossy green, petioled, alternate, and circular to heart-shaped. They are generally 5–13 cm long. Common greenbrier climbs other plants using green tendrils growing out of the petioles. [5]

Contents

The stems are rounded and green and are armed with sharp thorns. The flowers are greenish white, and are produced from April to August. The fruit is a bluish black berry that ripens in September. [5]

Cultivation and uses

The young shoots of common greenbrier are reported to be excellent when cooked like asparagus. [6] The young leaves and tendrils can be prepared like spinach or added directly to salads. [6] Being familiar with eating Smilax is a familiar trait in the South Carolina Lowcountry, where Smilax is often called 'chaineybriar.' The roots have a natural gelling agent in them that can be extracted and used as a thickening agent. [6]

Description

Like its common names suggest, Smilax rotundifolia is a green vine with thorns. It is a crawling vine that can tangle itself within other plants and climb with small tendrils. [7]

The plant can grow up to 20 feet long by climbing objects and vegetation. If there is nothing for it to climb upon it will grow along the ground. It has woody stems that are pale green in color and are glabrous, the youngest of which are often square-shaped. As the vine dies, the stem turns from green to a dark brown color. Along the stem there are often black-tipped thorns that are about 1/3-inch-long. Some stems of Common green brier do not have thorns.

The upper surfaces of the leaves are darker than the undersides. The rounded alternate leaves are about 2 to 5 inches long. [8] The leaves are glabrous and never glaucous. [9] There are 3 to 5 primary veins per leaf. Along the lower surfaces of the primary veins it is possible to find small prickles but they are not always present. The petioles are a quarter to half an inch long, light green in color and glabrous. Small sheaths with terminal tendrils are present at the base of each petiole. [9]

Common greenbrier has greenish white flowers that form in umbels of 3–20 flowers. The peduncles upon which the umbels of flowers are borne originate from the axils of the leaves. Male and female flowers are produced on different plant, as this genus is dioecious. Both male and female flowers are about the same size at a quarter inch long. The flowers bloom for about two weeks in late spring and early summer. After this blooming period the female flowers are replaced by a berry containing up to three seeds. [8]

Fire ecology

Smilax rotundifolia grows from rhizomes so it can resist fire by resprouting. Fires that open the canopies of dense forests encourage the growth of Smilax rotundifolia.

In New Hampshire it was found that Smilax rotundifolia responds to fire with rapid vigorous vegetative growth in the spring and fall. This was found in a prescribed burn in a white pine forest with low intensity flames (20 inches (50 cm) flame heights). After two years the amount of Smilax rotundifolia was back to the original density. Using different frequencies and intensities of fire no difference was found. [10]

Habitat and distribution

Smilax rotundifolia is found in the eastern half of the continental United States including Texas, South Dakota, and Oklahoma with the exception of Vermont. It ranges from Florida north into Northern Ontario. [11] Smilax rotundifolia is native to the USA.

Common greenbrier grows along roadsides, landscapes, clearings and woods. In clearings it often forms dense and impassable thickets. It can be found in almost all habitat types including wetlands.

Wildlife

The berries and leaves often persist into late winter. Smilax rotundifolia is a very important food plant in the winter while there are more limited food choices. Examples of wildlife that will eat the berries and leaves in the late winter and early spring are Northern Cardinals, white throated sparrows, white tailed deer, and rabbits. [10]

Conservation

For most of states S. rotundifolia is categorized as Least Concern due to its relative abundance. [12]

Uses

Food

Young shoots and uncurled leaves and tendrils can be eaten raw or cooked. [8]

Ethnobotany

In the genus Smilax there are many different uses of the plant for medical treatments around the world. The Cherokee Indians used Smilax rotundifolia to treat pain in the leg. Smilax rotundifolia vines and roots boiled together with tea was used to treat an upset stomach. When drinking this tea mixture a prayer was spoken. [13]

Taxonomy

The catbrier family, Smilacaceae, contains the genus Smilax. Smilax contains some 300 species including S. rotundifolia, the common green brier. Other species in the genus include Smilax glauca , the cat greenbrier, Smilax china , china root, and Smilax aspera, rough bindweed.

The genus Smilax was originally described by Linnaeus. Smilax rotundifolia was also described by Linnaeus. [14]

A vine is any plant with a growth habit of trailing or scandent stems, lianas or runners. The word vine can also refer to such stems or runners themselves, for instance, when used in wicker work.

<span class="mw-page-title-main">Smilacaceae</span> Family of flowering plants

Smilacaceae, the greenbriers, is a family of flowering plants. While they were often assigned to a more broadly defined family Liliaceae, most recent botanists have accepted the two as distinct families, diverging around 55 million years ago during the Early Paleogene. One characteristic that distinguishes Smilacaceae from most of the other members of the Liliaceae-like Liliales is that it has true vessels in its conducting tissue. Another is that the veins of the leaves, between major veins, are reticulate (net-shaped), rather than parallel as in most monocots.

<i>Smilax</i> Genus of flowering plants in the family Smilacaceae

Smilax is a genus of about 300–350 species, found in the tropics and subtropics worldwide. In China for example about 80 are found, while there are 20 in North America north of Mexico. They are climbing flowering plants, many of which are woody and/or thorny, in the monocotyledon family Smilacaceae, native throughout the tropical and subtropical regions of the world. Common names include catbriers, greenbriers, prickly-ivys and smilaxes. Sarsaparilla is a name used specifically for the Neotropical S. ornata as well as a catch-all term in particular for American species. Occasionally, the non-woody species such as the smooth herbaceous greenbrier are separated as genus Nemexia; they are commonly known by the rather ambiguous name carrion flowers.
