The name is often misspelled Diplarrhena, an error that began with George Bentham's Flora Australiensis in 1873
There are two species:
Diplarrena moraea Labill. is from Tasmania, Victoria and New South Wales
It has leaves up to a centimeter wide
The flowers are 5 to 6 centimeters wide, with blunt-tipped outer tepals 1.5 to 2.5 centimeters wide
The inner tepals are often tinged or veined with purple, and are yellowish at the tips.
Diplarrena latifolia Benth. from Tasmania
A larger plant with leaves 1 to 2.2 centimeters wide
The flowers are 6 to 8 centimeters wide with strongly purple-veined, yellow-tipped inner tepals
The species may be a regional variant of D. moraea
The cultivar 'Amethyst Fairy' is a large-flowered selection with darker markings on the inner tepals.
