''Dianella'' is a monocot genus of flowering plants.〔 H. Trevor Clifford, Rodney J.F. Henderson, and John G. Conran. 1998. "Hemerocallidaceae" pages 245-253. In: Klaus Kubitzki (editor). 1998. ''The Families and Genera of Vascular Plants'' volume III. Springer-Verlag: Berlin;Heidelberg, Germany. ISBN 978-3-540-64060-8 〕 They are commonly called flax lilies. In the APG II system of plant classification, ''Dianella'' was placed in the family Hemerocallidaceae. When that system was replaced by APG III in 2009, Hemerocallidaceae was combined with two other families to form a larger version of Xanthorrhoeaceae.〔Mark W. Chase, James L. Reveal, and Michael F. Fay. "A subfamilial classification for the expanded asparagalean families Amaryllidaceae, Asparagaceae and Xanthorrhoeaceae". ''Botanical Journal of the Linnean Society'' 161(2):132–136.〕 ''Dianella'' ranges from Japan to India, thence south to Australia and New Zealand; also occurring on many Pacific Islands. About half of the species are native to Australia.〔Starting out with Natives, John Wriggley & Murray Fagg〕 Several species are grown for their attractive foliage and shiny, blue to purple berries.〔 Anthony Huxley, Mark Griffiths, and Margot Levy (1992). ''The New Royal Horticultural Society Dictionary of Gardening''. The Macmillan Press,Limited: London. The Stockton Press: New York. ISBN 978-0-333-47494-5 (set). 〕 Estimates of the number of species range from 20〔 to more than 40.〔 The type species for the genus is ''Dianella ensata'',〔 ''Dianella'' In: Index Nominum Genericorum. In: Regnum Vegetabile (see ''External links'' below).〕 now a synonym of ''Dianella ensifolia''. ''Dianella'' is not well understood taxonomically and is in much need of revision. It 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. 〕 Not all taxonomists recognize the genus. In one paper on the classification of Xanthorrhoeaceae, ''Dianella'' and six other genera were subsumed in the genus ''Phormium''. ==Description== Characteristics: * Underground rhizome * Long, strappy leaves up to 1 meter long, ranging from deep to pale green, to blue-green * Blue flowers in spring, with 3 petals, 3 sepals, and prominent yellow stamens * Shiny blue to purple berries up to 1.5 centimeters in diameter, spherical or elongated with spongy pulp and shiny black seeds 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Dianella (plant)」の詳細全文を読む スポンサード リンク
