''Dryandra'' ser. ''Niveae'' is an obsolete series within the former genus ''Dryandra'' (now ''Banksia'' ser. ''Dryandra''). It was first published by George Bentham in 1870, and was given a new circumscription by Alex George in 1996, but was ultimately discarded in 2007 when Austin Mast and Kevin Thiele sunk ''Dryandra'' into ''Banksia''. ==According to Bentham== Bentham's definition of ''D.'' ser. ''Niveae'' was "Flowering stems from a creeping trunk very short, with one or few ovoid flower-heads surrounded by long floral leaves. Leaves pinnate with numerous rigid segments white underneath except in D. nana." Four species were included; the placement and circumscription of the series may be summarised as follows: :''Dryandra'' (now ''Banksia'' ser. ''Dryandra'') ::''D.'' sect. ''Eudryandra'' :::''D.'' ser. ''Armatæ'' (7 species) :::''D.'' ser. ''Floribundæ'' (5 species, 2 varieties) :::''D.'' ser. ''Concinnæ'' (4 species) :::''D.'' ser. ''Formosæ'' (5 species) :::''D.'' ser. ''Niveae'' ::::''D. nivea'' (now ''B. nivea'') ::::''D. arctotidis'' (now ''B. arctotidis'') :::::''D. arctotidis'' var. ''tortifolia'' (now ''B. tortifolia'') ::::''D. nana'' (now ''B. nana'') ::::''D. Preissii'' (now ''B. acuminata'') :::''D.'' ser. ''Obvallatæ'' (12 species) :::''D.'' ser. ''Gymnocephalæ'' (3 species) ::''D.'' sect. ''Aphragma'' (7 species, 2 varieties) 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「Dryandra ser. Niveae」の詳細全文を読む スポンサード リンク
