Pterogyne is a monotypic genus in the legume family, Fabaceae. The sole species is Pterogyne nitens. Spanish common names include guiraró, palo coca, or tipa colorado.[1] In Portuguese, it is commonly known as amendoim bravo, cocal or madeira nova. It is found in Brazil, Paraguay, Bolivia and Argentina.[1] It is threatened by habitat loss and harvesting for timber.[1]

Five guanidine alkaloid natural products were isolated from the leaves of Pterogyne nitens: nitensidine D, nitensidine E, pterogynine, pterogynidine, and galegine.[3]
