Ryania

Ryania is a genus of flowering plants in the family Salicaceae; it was previously listed in the now defunct family Flacourtiaceae.

The genus is significant partly because the ryanoid insecticides are derived from, and have the same mode of action as the alkaloid ryanodine, which was originally extracted from Ryania speciosa.

The Catalogue of Life includes these species:
 * Ryania angustifolia
 * Ryania canescens
 * Ryania dentata
 * Ryania mansoana
 * Ryania pyrifera
 * Ryania riedeliana
 * Ryania sauricida
 * Ryania speciosa
