Twelve images of Castanospermum australe, Moreton Bay Chestnut, Blackbean, Fabaceae or Leguminosae, pea family, native to Australia. Raw fruit is toxic, but early European settlers suggested that the roasted seeds were edible with a flavor likened to chestnuts. Source of castanospermine and related indolizidine alkaloids, with potential value in diabetes research.
