The three outer tepals are Шаблон:Cvt and the inner tepals Шаблон:Cvt long, each with five veins. The stamens have filament swellings Шаблон:Cvt long and yellow anthers.

Taxonomy and naming

Dianella longifolia was first described in 1810 by Robert Brown in his Prodromus Florae Novae Hollandiae et Insulae Van Diemen. The specific epithet (longifolia) is derived from Latin, meaning "long leaved".

Six varieties of D. longifolia have been described and accepted by the Australian Plant Census:

• Dianella longifolia var. fragrans R.J.F.Henderson that is only known from two collections from near Cardwell;
• Dianella longifolia var. grandis R.J.F.Henderson that is widespread in south-eastern Australia, from near Gympie to north of Adelaide;
• Dianella longifolia R.Br. var. longifolia, found throughout northern and eastern Australia, including the Kimberley region of Western Australia;
• Dianella longifolia var. stenophylla Domin in eastern Australia from near Gladstone to near Batemans Bay;
• Dianella longifolia var. stupata R.J.F.Henderson found mostly west of the Great Dividing Range in eastern Australia;
• Dianella longifolia var. surculosa R.J.F.Henderson that occurs in south-eastern Queensland and north-eastern New South Wales.

Distribution and habitat

Blueberry lily is widespread and common in non-arid parts of Australia, including the Kimberley region, eastern and southern Australia and northern Tasmania.
