Dianella is a genus of about forty species of flowering plants in the Monocotyledon family Asphodelaceae, commonly known as flax lilies.
Several species of this genus, or the whole genus, are sometimes referred to by the common name blue flax lily, particularly in Australia.
Description
Plants in the genus
Dianella are tufted
Perennial plant,
Rhizome herbs with fibrous or fleshy roots, more or less linear leaves with their bases overlapping, bisexual flowers with three sepals more or less similar to three blue, purple or white petals and a superior ovary, and the fruit a berry.
Taxonomy
The name
Dianella was first formally published by Jean-Baptiste Lamarck in 1786 in his
Encyclopédie Méthodique,
but this did not validly establish the name because Lamarck did not include a description of the new genus.
[Rodney J.F. Henderson. 1977. Typification of Dianella Lam. ex Juss. (Liliaceae). Taxon 26(1):131-137.] Antoine Laurent de Jussieu made it a correct name in 1789 when he published a description in the first edition of his
Genera Plantarum.
The name
Dianella is a reference to the Roman goddess Diana with the suffix
ella meaning "small".
The genus Dianella is closely related to Thelionema and Herpolirion.[Dion S. Devey, Ilia Leitch, Paula J. Rudall, J. Chris Pires, Yohan Pillon, and Mark W. Chase. "Systematics of Xanthorrhoeaceae sensu lato, with an emphasis on Bulbine". Aliso 22( Monocots: Comparative Biology and Evolution):345-351. ISSN 0065-6275.]
Distribution and habitat
Plants in the genus
Dianella occur in Africa, South-east Asia, the Pacific Islands including Hawaii, New Zealand and Australia. About half of the species are native to Australia.
