It can be described as having from seven to 40 genera, depending on the source and the method of circumscription used. The family Ternstroemiaceae has been included within Theaceae;〔Royal Botanic Gardens, Kew. ''Vascular Plant Families and Genera'': (Theaceae )〕〔Watson, L., & Dallwitz, M. J. (1992 onwards). ''The families of flowering plants''. (Theaceae )〕 however, the APG III system of 2009 places it instead in Pentaphylacaceae.〔 〕 == Family characteristics == Plants in this family are characterized by simple leaves that are alternate spiral to distichial, serrated, and usually glossy. Most of the genera have evergreen foliage, but ''Stewartia'' and ''Franklinia'' are deciduous. The toothed margins are generally associated with a characteristic Theoid leaf tooth, which is crowned by a glandular, deciduous tip.〔Stevens, P.F. 2003. Clusiaceae. In: Kubitzki, K. (Eds.), The Families and Genera of Vascular Plants. Springer, Hamburg, Germany〕 The flowers in this family are usually pink or white and large and showy, often with a strong scent.〔Luna I, Ochoterena H (2004) ‘Phylogenetic relationships of the genera of Theaceae based on morphology.’ Cladistics Vol. 20 223-270〕 The calyx consists of five or more sepals, which are often persistent in the fruiting stage, and the corolla is five-merous, rarely numerous. Plants in Theaceae are multistaminate, usually with 20-100+ stamen either free or adnate to the base of the corolla, and are also distinctive because of the presence of pseudopollen. The pseudopollen is produced from connective cells, and has either rib-like or circular thickenings. The ovary is often hairy and narrows gradually into the style, which may be branched or cleft. The carpels are typically opposite from the petals, or the sepals in the case of ''Camellia''. The fruits are loculicidal capsules, indehiscent baccate fruits or sometimes pomes. The seeds are few and sometimes winged, or in some generas covered by fleshy tissue or unwinged and nude.〔〔 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「Theaceae」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
