Wait-a-minute tree

Wait-a-minute tree, wait-a-bit tree, or wait-a-bit plant are common names for a variety of prickly plants that catch onto passers-by. These names come from the fact that the stems or other parts of the plant have numerous hooked thorns that tend to hook onto passers-by; the hooked person must stop ("wait a minute") to remove the thorns carefully to avoid injury or shredded clothing.

These names can refer to:

• Senegalia brevispica
• Senegalia greggii
• Some species of Asparagus
• Caesalpinia decapetala
• Mimosa aculeaticarpa
