Ottleya wrightii
Species of legume
Ottleya wrightii, synonym Lotus wrightii, is a species of legume native to the southwestern United States (Arizona, Colorado, New Mexico and Utah).[1][2] It is also said to occur in Nevada.[3] It is known as Wright's deervetch.
It has yellow flowers on many stems, arising from a single root crown. It was named after Charles Wright.[3]
The Zuni people apply a poultice of the chewed root to swellings that they believe are caused by being witched by a bullsnake.[4]
