Ryania speciosa[1][2] is a species of plants in the family Salicaceae.[3][4]

The species 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 this South American plant, which is also used as a piscicide.[5]
