I'm assuming "pigley" is part of the common name not a cultivar name. If so, the plant is already in the database here:
Pigeon Pea (Cajanus cajan)
IF "pigley" is a cultivar of pigeon peas, you would need to add it like this:
Primary common name: Pigeon Pea
Accepted botanical name(Genus species): Cajanus cajan
Cultivar: Pigley
