Steviodeae

Steviodeae is a botanical family of flowering plants within the order Aquifoliales. It primarily encompasses the genus Stevia, which is renowned for its sweet-tasting leaves. The family is characterized by perennial herbs and shrubs, often featuring opposite or whorled leaves, with small, white or pale flowers that are typically arranged in clusters.

The most notable member of the Steviodeae family is Stevia rebaudiana, commonly known as sweetleaf or sugarleaf. Native to South America, particularly Paraguay and Brazil, Stevia rebaudiana has gained worldwide recognition due to its natural sweetening properties. The plant produces steviol glycosides, which are compounds significantly sweeter than sugar and are used as low-calorie sweeteners in various food and beverage products.

The genus Stevia was first described in the 19th century, but widespread commercial cultivation began in the late 20th century, driven by increased interest in natural and health-conscious sweeteners. Apart from its culinary use, Stevia is also valued for its potential health benefits, including its negligible impact on blood sugar levels, making it popular among diabetics and those seeking alternative sweeteners.

Taxonomically, the family Steviodeae is relatively small, with molecular studies supporting its placement within the order Aquifoliales. Its members are primarily concentrated in the native regions of South America, although cultivation and research have led to its global dissemination.

Overall, Steviodeae, with its economically and nutritionally significant genus Stevia, represents an important group of plants with a notable role in natural sweetening and health-related industries.
