About Senna bauhinioides (A.Gray) H.S.Irwin & Barneby

It is native to Arizona, New Mexico, and Texas in the United States, as well as northern Mexico. This species has also been introduced to the US state of Maryland. It is an opportunistic species that is unpalatable to livestock, so its presence is considered an indicator of overgrazing.
