Amphicarpaea - A Diverse Genus of Flowering Plants

Amphicarpaea is a genus of flowering plants in the family Apocynaceae, commonly known as carpetweeds or dog's mercury. The name "amphicarpaea" comes from the Greek words "amphi" meaning "both" and "carpaea" meaning "fruit", referring to the fact that the fruits of these plants are both dry and dehiscent (meaning they split open at maturity).

Amphicarpaea is a diverse genus with over 100 species found in tropical and subtropical regions around the world, particularly in Africa, Asia, and Australia. The plants are typically herbaceous or subshrubby, with simple leaves and showy flowers that range in color from white to pink, yellow, orange, and red. The fruits of Amphicarpaea species are usually capsules or follicles that contain numerous small seeds.

Amphicarpaea species have been used in traditional medicine for a variety of purposes, including as antidotes for poisoning, anti-inflammatory agents, and antibacterial agents. Some species are also used as ornamental plants in gardens and landscapes. However, some species of Amphicarpaea can be toxic and should be handled with caution.
