''Volkameria'' is a genus of flowering plants in the family; Lamiaceae. It is pantropical in distribution.〔(Kew World Checklist of Selected Plant Families )〕〔Yao-Wu Yuan, David J. Mabberley, Dorothy A. Steane, and Richard G. Olmstead. 2010. "Further disintegration and redefinition of ''Clerodendrum'' (Lamiaceae): Implications for the understanding of the evolution of an intriguing breeding strategy". ''Taxon'' 59(1):125-133.〕 Many of the species are found in coastal habitats. The species of ''Volkameria'' are mostly shrubs, sometimes subshrubs or lianas, rarely small trees. The stems have swollen nodes. The flowers are usually fragrant. The fruit matures black or brown, separating into four corky pyrenes. ''Volkameria aculeata'' and ''Volkameria glabra'' are grown as ornamentals in the tropics.〔George W. Staples and Derral R. Herbst "A Tropical Garden Flora" Bishop Museum Press: Honolulu (2005)〕 ''Volkameria heterophylla'' is also known in cultivation.〔Anthony J. Huxley, Mark Griffiths, and Margot Levy (editors). 1992.

In: Carolus Linnaeus. 1753. ''Species Plantarum'' volume 2. Laurentii Salvii. (see ''External Links'' below).〕 According to OED the genus was named after Johann Georg Volckamer (1616-1693), a German botanist, though other sources give credit to his son, Johann Georg Volckamer, the Younger (1662-1744),〔Carolus Linnaeus. 1737. ''Critica Botanica'' page 95〕〔Umberto Quattrocchi. 2000. ''CRC World Dictionary of Plant Names'' volume IV, page 2809. CRC Press: Boca Raton; New York; Washington,DC;, USA. London, UK. ISBN 978-0-8493-2673-8 (set). (see ''External links'' below).〕 or to Johann Christoph Volkamer (1644-1720), another German botanist. In 1895, John Isaac Briquet defined the genus ''Clerodendrum'' broadly, to include all of those species now placed in ''Rotheca'', ''Clerodendrum'', ''Volkameria'', and ''Ovieda''.〔John Isaac Briquet. 1895. "''Clerodendrum''" pages 174-176. In: "Verbenaceae" pages 132-182. In: ''Die Natürlichen Pflanzenfamilien'' volume IV, part 3a. Verlag von Wilhelm Engelmann: Leipzig, Germany.〕 This was considered questionable by many, but for the next 100 years, Briquet's circumscription was usually followed, mostly because of confusion and uncertainty regarding this group of at least 200 species.〔 In 2010, a molecular phylogenetic analysis of DNA sequences showed that most of the ''Clerodendrum'' species that had been in ''Volkameria'' were more closely related to ''Aegiphila'', ''Ovieda'', ''Tetraclea'', and ''Amasonia'' than to other species of ''Clerodendrum''.〔 (See the phylogenetic tree at Lamiaceae). Following these results, ''Volkameria'' was reinstated. Some species that had been erroneously placed in ''Volkameria'' were excluded. Some of the poorly known species in ''Clerodendrum'' might still need to be transferred to ''Volkameria''. 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「Volkameria」の詳細全文を読む スポンサード リンク
