How a discover a plant called Fabaceae:

Hello everyone this my first time to post in this wonderful community I made research on a plant called “Delonix Regia which they family name is called “Fabaceae”
This a plant that is used as percussion instrument when it is dry mostly in Western Africa Nigeria when you shake it and hit it slowly on your hands it produces a very good sounds to hearing and it also use to replace fire wood in the farm cos it burns at faster rate I believe you are a bit familiar with it thanks.
