Stegnosperma

Stegnosperma is a genus of flowering plants, consisting of three species of woody plants, native to the Caribbean, Central America, and the Sonoran Desert. These are shrubs or lianas, with anomalous secondary thickening in mature stems, by successive cambia.

== Characteristics == Leaves are alternate, entire, 2–5 cm in length, tapering at both ends. Flowers are small (5–8 mm), five-merous, with white petal-like sepals, and a superior ovary. They are arranged in short racemes, usually no more than 10 cm long, shorter in S. watsonii. The fruit is a capsule 5–8 mm in diameter: it contains small (2–3 mm) black seeds with a conspicuous reddish aril.
