Brodiaeoideae are a monocot subfamily of flowering plants in the family Asparagaceae, order Asparagales. They have been treated as a separate family, Themidaceae. They are native to Central America and western North America, from British Columbia to Guatemala.〔Ole Seberg. 2007. "Themidaceae" page 404. In: Vernon H. Heywood, Richard K. Brummitt, Ole Seberg, and Alastair Culham. ''Flowering Plant Families of the World''. Firefly Books: Ontario, Canada.〕 The name of the subfamily is based on the type genus ''Brodiaea''. In molecular phylogenetic analyses, Brodiaeoideae is strongly supported as monophyletic. It is probably sister to Scilloideae.〔J. Chris Pires, Ivan J. Maureira, Thomas J. Givnish, Kenneth J.

''Aliso'' 22(''Monocots: Comparative Biology and Evolution''):287-304. ISSN 0065-6275.〕 Recent treatments have divided Brodiaeoideae (or Themidaceae) into 12 genera.〔Knud Rahn. 1998. "Themidaceae" pages 436-441. In: Klaus Kubitzki (general editor) with Klaus Kubitzki, Herbert F.J. Huber, Paula J. Rudall, Peter F. Stevens, and Thomas Stützel (volume editors). ''The Families and Genera of Vascular Plants'' volume III. Springer-Verlag: Berlin;Heidelberg, Germany. ISBN 978-3-540-64060-8〕 The monophyly of several of the genera remains in doubt.〔J. Chris Pires, Michael F. Fay, Warren S. Davis, Larry Hufford, Johan Rova, Mark W. Chase, and Kenneth J. Sytsma. 2001. "Molecular and morphological phylogenetic analyses of Themidaceae (Asparagales)". ''Kew Bulletin'' 56(3):601-626.〕 As currently circumscribed, the largest genera are ''Triteleia'', with 15 species, and ''Brodiaea'', with 14.〔Flora of North America Editorial Committee. 2002.

Springer Science+Business Media. ISBN 978-1-4020-9608-2.〕 Perennial herbs arising from a starchy corm; a new corm arising each year from the old one. Leaves linear, often fleshy, forming a closed sheath at their base. Veins parallel. Inflorescence an umbel, or rarely a single flower, at the apex of a solitary scape. Flowers bisexual, actinomorphic. Tepals all similar, in 2 whorls of 3. Fertile stamens 6, or 3 and alternating with 3 staminodes. Stamens and staminodes inserted on tepals. Anthers basifixed and introrse. Ovary superior and trilocular. Fruit a loculicidal capsule. Seed covered with phytomelan. 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「Brodiaeoideae」の詳細全文を読む スポンサード リンク
