C.rossii can be confused with rounded noon-flower Disphyma crassifolium subsp. clavellatum, which has also been erroneously called "karkalla" and "beach bananas" in the Australian native food trade.[3]

Description edit

Karkalla leaves are succulent, 3.5–10 cm (1.4–3.9 in) long and 1 cm (0.4 in) wide, and curved or rarely straight. The flowers are light purple in colour, and 6 cm (2.4 in) wide. The globular purplish red fruit is about 2.5 cm (1 in) long and 1.5 cm (0.6 in) wide.[4]

Distribution edit

The species occurs in the states of Western Australia, South Australia, Tasmania and Victoria.[5] It can be found year-round in large patches covering sand dunes close to the ocean, due to its hardy nature and salt resistance.[6]

Uses edit

Aboriginal people eat the fruit traditionally, fresh and dried. The salty leaves were also reported to have been eaten with meat. The salty edible leaves should not be confused with rounded noon-flower, which also has edible leaves and is marketed as "karkalla".

Extracts of the plant have significant in vitro antioxidant, antiplatelet, and anti-inflammatory activity.[7]
