The plant genus Anigozanthos consists of 11 different species which are endemic to Western Australia. Commonly known as kangaroo paw, both species and hybrids are used for domestic and export cut flower production and are also important as ornamental native plants that attract bees, nectar-eating birds and butterflies into the garden.
Several foliar diseases of kangaroo paws are serious enough to make the plants unsellable, but the major foliar disease is ink disease or ink spot. Ink disease may be caused by Alternaria alternata which is a fungal pathogen that has been identified on kangaroo paws plants with ink disease symptoms . The symptoms of ink disease are large black blotches on the leaves.
