Rhynchosia precatoria DC. Piule  - Fabaceae

The seeds of piule, Rhynchosia precatoria, are similar in size and color to the rosary pea, Abrus precatorius, and like Abrus are used as prayer beads.  However, the hilum, (the point of attachment of the seed to the fruit) is in the red area of Rhynchosia and in the black area in Abrus.

Most of the 300 species of Rhynchosia growing in the tropics and subtropics of the New and Old Worlds are trailing or climbing vines.  Several species are called piule which is also the name for all the hallucinogenic morning glory seeds.6
